Rockford engineers designed the Punch 55.2, 75.2, 125.2 and 225.2
amplifiers to withstand the rugged automotive environment while delivering
superiorsoundqualityina flexible, reliable, andefficientpackage. TRANS•ANA
is a low voltage circuit in the preamp stage of all Punch .2 amplifiers that
lets the music sound crystal clear and very real, even when played at high
volume levels. This is matched with TOPAZ, a unique grounding circuit used
to eliminate noise problems associated with car audio systems and their
installation. Flexibility is accomplished with the use of a built-in XCard.
Reliability is all but guaranteed with the use of a protection circuit called
NOMAD, while MOSFET and DSM (Discrete Surface Mount) technology
improve amplifier efficiency. The result of these components give the Punch
amplifier awesome sound quality in a “Bullet Proof” package. An explana-
tion of these technologies, most of which are exclusively designed and
patented by Rockford, are described in the Technical Design Features.

ESIGN FEATURES
◆ TRANS•ANA
(TRANSconductance Active Nodal Amplifier)
The TRANS•ANA (TRANSconductance Active Nodal Amplifier) is a circuit
that allows the audio signal to pass through the amplifier at low voltage. The
signal is directly level-shifted to the fixed high voltage rails via a pair of driver
transistors. Signal linearity is assured by an active node formed by the drive
transistors at ultrasonic frequencies. This allows amplifier performance
similar to trans•nova which is highly stable and linear while utilizing the
advantages of a non-floating power supply.
THE RESULT: An extended frequency bandwidth accurately supplied to the
output stages of the amplifier.
◆ MEHSA (Maximum Efficiency Heat Sink Application)
The MEHSA (Maximum Efficiency Heat-Sink Application) is a proprietary
process that yields up to 5 times better heat transfer than traditional FET
mounting techniques using the exact same components. A multi-layer
insulated metal substrate operating with minimal thermal resistance spreads
heat both downward & outward to quickly dissipate heat from each device
across the heat sink. This process combined with our DSM technology and
MOSFET devices allow us to squeeze more watts per cubic inch from every
output device as well as provide consistent thermal stability.
THE RESULT: Optimized power output, enhanced thermal stability, and
maximum component reliability.
◆ TOPAZ (Tracking Operation Pre-Amplifier Zone)
The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solves ground
loopnoiseproblemscommontoautomotiveamplifierdesign. Thisinnovative
newdevelopmentallowsvastlyimprovedisolationoftheinputsignalgrounds
from the power supply ground of the amplifier. This is accomplished by
allowing the source unit to control the potential “environment” of the entire
input structure or “zone” of the amplifier. This process improves the noise
rejection of the amplifier by 30-40dB – an astounding 30-100 times better
than amplifiers without TOPAZ.
THE RESULT: Elimination of troublesome ground loop noise between source
and amplifier.

◆ DSM (Discrete Surface Mount) Technology
The DSM (Discrete Surface Mount) manufacturing process combines the
advantages of both discrete components and integrated circuitry. Rockford
FosgateistheonlyAmericanamplifiermanufacturertohaveinvestedmillions
into this process. DSM components differ from conventional discrete compo-
nents in different ways. They are more compact, more rugged, and they
efficiently dissipate generated heat. Using them wherever appropriate allows
the advantages associated with discrete circuitry to be retained while also
providing room for both highly advanced processing features and generous
PC board copper paths where needed. Their short lead-out structures allow
maximum audio performance and highest signal-to-noise ratios to be
obtained in amplifiers of desirable package size without resorting to “ampli-
fier-on-a-chip” shortcuts. These advantages are shown below in Figure 1.
THE RESULT: Fewer connections, improved reliability, shorter signal paths,
superior signal-to-noise ratio and awesome sonic performance.

◆ XCard (Internal Crossover)
The Punch amplifiers utilize internal active crossovers. These crossovers have
many performance advantages such as using discrete components for exact
frequency adjustments which are far superior to potentiometers. Additionally,
the XCard can be configured for high-pass, low-pass and full range
operation. With slight modifications, many crossover frequencies and slope
configurations can be achieved.
THE RESULT: Increased system design flexibility with a precise electronic
crossover without the limitations of conventional potentiometer designs.

◆ MOSFET Devices
Rockford Fosgate is one of the few manufacturers in the sound community
to utilize MOSFET devices in both the power supply and the output stages.
MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer
several important inherent advantages over the 30 year old technology of bi-
polar design. These advantages include: thermal stability, switching speed,
ultra low output impedance and wider bandwidth linearity. In addition,
MOSFETs operate very similarly to vacuum tubes in that they are more linear
than bi-polar transistors. However, MOSFETs can deliver the midrange clarity
without the limitations of transient response and high frequency phase
shifting normally associated with tube operation.
THE RESULT: Operational characteristics similar to vacuum tubes without
the performance limitations of tube design.
◆ NOMAD (NOn-Multiplying Advanced Decision)
The Punch amplifiers use an analog computer process to maximize safe
output power under all operating conditions. The innovative NOMAD (NOn-
Multiplying Advanced Decision) system is the most sophisticated version of
this technique ever used, bringing previously unavailable levels of accuracy,
stability, temperature immunity and reliability to this critical process. NOMAD
makes advanced decisions based on device voltages to precisely control the
awesome levels of current available in the output MOSFETs to safe values –
but only when absolutely needed.
THE RESULT: Extremely fast protection system that always protects the
amplifier and never degrades the sound.
◆ Punch EQ
The Punch EQ helps correct for acoustical deficiencies in the listening
environment. Two unique potentiometers that control bass and treble
compensate for the response errors present in most car environments. Unlike
conventional tone controls, Punch EQ corrects the specific problems of poor
low bass response and high frequency rolloff.
THE RESULT: Full range sound without excessive boost in areas where it is
not needed.

The following is a list of tools you will need for installing the Punch amplifier:
Allen wrenches 9/64" & 3/32" (included)
Wire strippers
Electric hand drill w/assorted bits
17' (518.16cm) Red Power Wire
12' (365.76cm) Remote Turn-On Wire
1.5' (45.72cm) Black Grounding Wire

This section focuses on some of the vehicle considerations for installing your
new Punch amplifier. Checking your battery and present sound system, as
well as pre-planning your system layout and best wiring routes will save
installation time. When deciding how to lay out your new system, be sure that
each component will be easily accessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules:
1. Be sure to carefully read and understand the instructions before attempt-
ing to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.
3. For easier assembly, we suggest you run all wires prior to mounting your
amplifier in place.
4. Route all of the RCA cables close together and away from any high
current wires.
5. Use high quality connectors for a reliable installation and to minimize
signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel
lines, brake or hydraulic lines, vacuum lines or electrical wiring when
working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires inside the
vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber or plastic
grommets to protect any wires routed through metal, especially the
firewall.
9. ALWAYS protect the battery and electrical system from damage with
proper fusing. Install a fuseholder and appropriate fuse on the +12V
power wire within 18” (45.7 cm) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paint from the
metal to ensure a good, clean ground connection. Grounding connec-
tions should be as short as possible and always be connected to metal
that is welded to the main body, or chassis, of the vehicle.

O UNTING LO CATIO N
The mounting location and position of your amplifier will have a great effect
on its ability to dissipate the heat generated during normal operation. The
design of our cast aluminum heatsink serves to easily dissipate the heat
generated over a wide range of operating conditions. However, to maximize
the performance of your amplifier, care should be taken to ensure adequate
ventilation.
Trunk Mounting
Mounting the amplifier vertically on a surface with the fin grooves running
up and down will provide the best cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will work but provides less
cooling capability than vertical mounting.
Mounting the amplifier upside down to the rear deck of the trunk will not
provide proper cooling and will severely affect the performance of the
amplifier and is strongly not recommended.
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as
you provide a sufficient amount of air for the amplifier to cool itself. If you
are going to mount the amplifier under the seat of the vehicle, you must have
at least 1" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the
amplifier's heatsink in the passenger compartment will not provide proper
cooling and will severely affect the performance of the amplifier and is
strongly not recommended.
Engine Compartment Mounting
Rockford Fosgate amplifiers should never be mounted in the engine
compartment. Not only will this void your warranty but could create an
embarrassing situation caused by the ridicule from your friends.

BATTERY AN D
C
H ARG IN G
Amplifiers will put an increased load on the vehicle's battery and charging
system. We recommend checking your alternator and battery condition to
ensure that the electrical system has enough capacity to handle the
increased load of your stereo system. Stock electrical systems which are in
good condition should be able to handle the extra load of any Rockford
amplifier without problems, although battery and alternator life can be
reduced slightly. To maximize the performance of your Rockford Fosgate
amplifier, we suggest the use of a heavy duty battery and an energy storage
capacitor.

I RI N G T H E SYST EM
CAUTION: Avoid running power wires near the low level input cables,
antenna, power leads, sensitive equipment or harnesses. The power
wires carry substantial current and could induce noise into the audio
system.
• For safety, disconnect the negative lead from the battery prior to beginning
the installation.
1. Configure the internal XCard crossovers prior to installation. Refer to
“Using the XCard” (page 14) for further information.
2. Plan the wire routing. Take care when running signal level RCA cables
to keep them close together but isolated from the amplifier's power cables
and any high power auto accessories, especially electric motors. This is
done to prevent coupling the noise from radiated electrical fields into the
audio signal. When feeding the wires through the firewall or any metal
barrier, protect them with plastic or rubber grommets to prevent short
circuits. Leave the wires long at this point to adjust for a precise fit at a
later time.
3. Prepare the Power cable for attach-

Punch 55.2, 75.2, 125.2
Trim the power cable to within 18" of the battery and install the protective
rubber boot, which is packed with the fuseholder, over the end of the wire.
Strip 3/8" of insulation from the wire and insert into the end of the
fuseholder, then crimp it in place. Slide the rubber boot into place to cover
the connection. Use the section of cable that was trimmed earlier and
connect it to the other end of the fuseholder.
Punch 225.2
Mount the fuseholder within 18" of the battery using two (2) #8 screws.
Disassemble the fuseholder. You should have 2 black plastic end caps,
2 gold-plated fuse clips, a plastic spacer and the fuseholder body. Trim
the amplifier power cable to reach the fuseholder and strip the wire 3/8".
Slide one of the end caps over the wire (narrow end first) and insert the
wire into one of the fuse clips. Tighten the set screw. Screw the black end
cap to the fuseholder body to secure the cable. Use the section of cable
that was trimmed earlier and connect it to the other end of the fuseholder.
Install the plastic spacer in the fuseholder and attach the cable to the
fuseholder body.
NOTE: The B+ cable MUST be fused 18" or less from the vehicle's
battery. Install the fuseholder under the hood and prepare the cable
ends as stated above. Connections should be water tight.
4. Strip 3/8" from the battery end of the power cable and crimp a large ring
terminal to the cable. Use the ring terminal to connect to the battery
positive terminal. Do not install the fuse at this time.
5. Prepare a length of cable to be used for the ground connection. Strip
5/8" of insulation from the end of the cable as described previously
and connect to the appropriate terminal of the amplifier. Prepare the
chassis ground by scraping any paint from the metal surface and
thoroughly clean the area of all dirt and grease. Strip the other end of the
wire and attach a ring connector. Fasten the cable to the chassis using a
non-anodized screw and a star washer.
6. Prepare the REM turn-on wire for connection to the amplifier by stripping
1/4" of insulation from the wire end and crimping an insulated spade
connector in place. Slide the connector over the REM terminal on the

amplifier. Connect the other end of the REM wire to a switched 12 volt
positive source. The switched signal is usually taken from the source
unit's auto antenna or the accessory lead. If the source unit does not have
these outputs available, the recommended solution is to wire a mechani-
cal switch in line with a 12 volt source to activate the amplifier.
7. Securely mount the amplifier (with supplied screws) to the vehicle or
amp rack. Be careful not to mount the amplifier on cardboard or plastic
panels. Doing so may enable the screws to pull out from the panel due
to road vibration or sudden vehicle stops.
8. Connect the source signal to the amplifier by plugging the RCA cables
into the input jacks at the amplifier.
9. Connect the speakers. Strip the speaker wires 5/8". Insert the bared wire
into the speaker terminal and tighten the set screw to secure into place.
Be sure to maintain proper speaker polarity. DO NOT chassis ground
any of the speaker leads as unstable operation may result.
10. Perform a final check of the completed system wiring to ensure that all
connections are accurate. Check all power and ground connections for
frayed wires and loose connections which could cause problems.
11. After the final inspection is complete, install the power fuse and enjoy
listening. During the initial listening period, you may need to “fine tune”
any phasing and level settings within your particular vehicle. To aid in
this procedure, play a track with high musical content and cruise around
your neighborhood. After fully evaluating the transient response of your
system and making any final adjustments, all your neighbors within a
1 mile radius will assume that you have just successfully completed
another upgrade to your audio system for which they will probably spill
thumbtacks on your driveway.

USING PASSIVE CROSSOVERS
i
o
n
A passive crossover is a circuit that uses capacitors and/or coils and is placed
on speaker leads between the amplifier and speaker. The crossover delegates
a specific range of frequencies to the speaker for optimum driver performance.
A crossover network can perform one of three functions: High-Pass (capaci-
tors), Low-Pass (inductors or coils) and Bandpass (combination of capacitor
and coil).
The most commonly used passive crossover networks are 6dB/octave
systems. These are easy to construct and require one component per filter.
Placing this filter in series with the circuit will reduce power to the speaker by
6dB/octave above or below the crossover point depending on whether it is a
high-pass or low-pass filter. More complex systems such as 12dB/octave or
18dB/octave can cause impedance problems if not professionally designed.
Passive crossovers are directly dependent upon the speaker's impedance and
component value for accuracy. When passive crossover components are
used in multiple speaker systems, the crossover's effect on the overall
impedance should be taken into consideration along with the speaker's
impedance when determining amplifier loads. CAUTION: The Punch ampli-
fiers are not recommended for impedance loads below 2Ωstereo and 4Ω
bridged (mono) loads.

About the Dynamic Power Measurements
The Audio Graph PowerCube is a test instrument used to measure the output of
an amplifier in accordance with IHF-202 industry standards. The IHF-202
standard is a dynamic power measurement and was developed as a means of
measuring power in a manner that best represents the Real World operation of an
amplifier. Many manufacturers, including Rockford Fosgate, at times will measure
amplifier power into a fixed resistor (4 ohm, 2 ohm). While this method is useful
in some types of evaluation and testing, it is not representative of an amplifier that
is connected to a speaker and playing music.
Music
Music is dynamic; the sound waves are complex and constantly changing. In
order to simulate this, the IHF-202 standard calls for the input signal to the
amplifier to be a 1kHz bursted tone. This signal is input (on for 20 milliseconds)
and reduced 20dB for 480 milliseconds. The signal is gradually increased in level
until the amplifier's output exceeds 1% Total Harmonic Distortion (THD). At 1%
distortion becomes audible, therefore, any power produced above that level is
considered unusable. Many manufacturers represent their amplifiers' output
power in excess of 10% distortion. They use many names for this measurement,
such as Total Maximum Power or Maximum Output Power. This is not indicative
of the actual usable output power.
Listening to Loudspeakers - Not Resistors
A loudspeaker is not a resistor. A resistor's value (resistance measured in ohms)
isfixed. Aloudspeaker'simpedanceisdynamic. Itisconstantlychanginginvalue,
dependent upon the frequency of the input signal. Therefore, measuring power
with the amplifier loaded into a 4 ohm resistor is not the same as measuring power
with the amplifier connected to a 4 ohm speaker. Most people do not listen to
music through a resistor.
A 4 ohm speaker may experience a drop in impedance 4-6 times lower than its
nominal (printed) impedance. A speaker will also create phase shifts in the signal
that is passed through it. These phase shifts happen because a speaker is an
inductor(voicecoil) anda capacitor(complianceofthesurround/spider), aswell
as a resistor (voice coil wire).
To simulate a speaker the Audio Graph PowerCube measures output power into
20 different loads. It tests at 8 ohms, 4 ohms, 2 ohms and 1 ohm. Each of these
impedances is also tested at –60°, –30°, 0°, +30° and +60° phase angles.
These different impedances and phase angles represent the shifts in impedance
and phase that can occur in a typical loudspeaker.

Information Cubed
The data acquired in the testing procedure is then graphed in the form of a
3-dimensional cube, hence the name PowerCube.
The Phase Angle is expressed on the horizontal axis, the Output Voltage is
presented on the vertical axis and the Impedance is displayed on the Z axis.
Output Power, in watts, is listed on the left hand side for each impedance at
each phase angle.

• Example of a Punch 200.2 PowerCube
What is an Amplifier?
An amplifier by definition is a voltage generating device, recreating the signal
which is input to it identically but with increased volume. It will be connected
to a reactive load (the speaker). The impedance of this load and phase of the
signal passing through the load will vary, dependent upon the frequency of
the input signal (music).
Therefore, a perfect amplifier will be able to maintain the same output voltage
regardlessofloadcharacteristicsandwillnotalterthesignalitisreproducing.
A perfect amplifier when measured by the Audio Graph PowerCube would
present data that forms a perfect cube. Unfortunately, amplifiers are not
perfect. The laws of physics generally prevent it. A great amplifier is about the
best one can hope to attain.
As you can see by the PowerCube and as you will experience by listening,
your Punch amplifier is a GREAT AMPLIFIER!

LEA DETENIDAMENTE LAS SIGUIENTES INSTRUCCIONES DE INSTALACION DEL
PRODUCTO. EVITARA POSIBLES DAÑOS A VD., AL VEHICULO O AL PRODUCTO.
INTRODUCCION
Los ingenieros de Rockford han diseñado los amplificadores Punch.2 para
ofrecer en el dificil entorno de un automóvil una calidad de sonido superior en
un producto flexible, fiable y eficiente. Trans•ana es un circuito de baja tensión
en la etapa de preamplificación de los amplificadores Punch.2 que permite que
la musica suene limpia y cristalina y muy real, incluso a altos niveles de
audicion. Esto se complementa con el TOPAZ, un circuito exclusivo de masa
utilizado para eliminar los ruidos asociados con las instalaciones de car-audio.
La flexibilidad esta garantizada con el uso de la XCard incorporada. La
fiabilidad se refuerza con el uso de un circuito de proteccion llamado NOMAD,
mientras que los MOSFET y la tecnologia DSM (montaje discreto en superficie)
aumentan la eficiencia del amplificador. La combinacion de todos estos
componentes dan al amplificador Punch una impresionante calidad de sonido
en un chasis discreto. Mas adelante encontrará mas explicaciones de todas
estas tecnologías, la mayoria de ellas usados en exclusiva y patentadas por
Rockford.

INTRODUCTION
Les ingénieurs de Rockford Fosgate ont conçu l'amplificateur Punch.2 pour
supporter l'environnement rude de l'automobile en délivrant une qualité de son
supérieure dans un ensemble efficace, fiable et flexible. Trans• ana est un circuit
de bas voltage dans l'étage de préamplification de tous les ampificateurs
Punch.2 qui reproduit un son musical clair comme du cristal et très réel, même
à très haut volume. Ceci est accompagné du TOPAZ, un circuit unique employé
pouréliminerlesproblèmesdebruitsparasitesassociésauxsystémesaudiomobile
et leur installation. La flexibilité est assurée par l'emploi d'une XCard incorporée.
La fiabilité est garantie grâce au circuit de protection NOMAD, la technologie
MOSFET et DSM (Composants Montés en Surface) améliorent l'efficacité de
l'amplificateur.
L'ensemble de ces atouts donne à l'amplificateur Punch une qualité de son
inégalable sous une carrosserie “pare-balles.”

BITTE LESEN SIE DIESE GEBRAUCHSANLEITUNG ZUERST SORGFÄLTIG DURCH.
DAS KANN SIE VOR DEM FALSCHEN EINSATZ, AUSFALLEN ODER SOGAR
BESCHÄDIGUNG DES PRODUKTES ODER IHRES FAHRZEUGES SCHÜTZEN.
EINLEITUNG
Rockford Ingenieure haben die Punch.2 Verstärker entwickelt. Mit höchstem
Technologie-Standart, hervorragender Klangqualität, einfacher Handhabung
und bester Servicefreundlichkeit Trans•ana ist eine Nieder-Volt Schaltung im
Vorverstärkerteil aller Pünch.2 Verstärker die für kristallklaren Klang auch bei
sehr hohen Lautstärken sorgt. TOPAZ, eine einzigartige Erdungsschaltung
verhindert und unterdrückt Einstreuungen und Störungen die nur allzu oft Car
Audio Systeme beeinträchtigen. Flexibilität durch die Vielfalt der Aktivweiche mit
ihren XCards, lange Lebensdauer durch die Schutzschaltung NOMAD und der
Einsatz von MOSFET Transistoren und DSM (Discrete Surface Mount), machen
diese Verstärker so effizient. Das Ergebnis all dieser Komponenten machen
Punch-Verstärker so einzigartig und in ihrer Klangqualität nahezu unschlagbar.
Eine genauere Beschreibung dieser Technologien, die gröbtenteils einzigartig
und von Rockford patentiert sind, finden Sie unter Technical Design Features.
EINBAUORT
Im Fahrzeugkofferraum
Der vertikale Einbau der Endstufen, das bedeutet, dab die Kühlrippen von oben
nach unten verlaufen, gibt dem Verstärker die beste Kühlung.
Auf der Beifahrerseite
SolltederVerstärkeraufderBeifahrerseitemontiertwerden, soistessehrwichtig,
für eine ausreichende Kühlung zu sorgen. Sollte der Verstärker z.B. unter dem
Beifahrersitz montiert werden, sollte dem Kühlkörper mindestens ein Luftspalt
von 3 cm bleiben, um so für eine ausreichende Kühlung zu sorgen.
Einbau
Zur Sicherheit klemmen Sie den Negativ-Pol der Batterie während des gesamten
Einbaues ab.
B+ Anschluβ
Die Plus-Leitung MUβ ca. 40 cm nach dem Plus-Pol der Batterie abgesichert
sein. Preparieren Si die Kabellängen und montieren Sie den Sicherungshalter im
Motorraum. ALLE Verbindungen müssen wasserdicht sein.

GND Anschluβ
Preparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). Preparieren Sie
die Anschlubstelle des Erdungskabels, indem Sie das Metall gründlich
reinigen und vom Lack befreien. Befestigen Sie nun die Erdung an dieser
Stelle mit einer Schraube.
REM Anschluβ
Verbinden Sie das Ein-und Ausschaltungskontroll-Kabel mit Ihrem Radio
(12 Volt positiv). Normalerweise verwenden Sie hierfür die Ant.-Remote
Ihres Radios oder ein eigens dafür vorgesehenes Kabel (Amp-Remote).
Sollte Ihr Radio diesen Anschlub nicht besitzen, so verwenden Sie eine 12
Volt Spannung, die Sie durch einen Schalter ein- und ausschalten können.

INTRODUZIONE
Gli ingenieri Rockford hanno progettato la serie di amplificatori Punch.2 per
resistereall'osticoambienteautomobilisticomentresuonanoconuna musicalitá
superiore, offrendo un insieme versatile, affidabile ed efficiente. Trans•ana é un
circuito a bassa tensione dello stadio preamplificatore del Punch.2 che permette
al suono di essere cristallino e reale anche in presenza di volumi molto
elevati…tutto questo é accoppiato TOPAZ, un exclusivo circuito di massa
impiegato per eliminare i problemi di rumore comunemente presenti negli
impianti car audio. Il massimo della versatilitá é raggiunto con l'impiego delle
XCard. L'affidabilitá é completamente garantita dall'impiego di un circuito di
protezione chiamato NOMAD, mentre l'uso di MOSFET e della tecnologia DSM
(Discrete Surface Mount) permette di raggiungere efficienze elevatissime. Il
risultato finale di tutte queste tecnnologie moderne é che gli amplificatori Punch
suonano meravigliosamente e sono indistruttibili, a “prova di proiettile.” Una
spiegazione di queste tecnologie innovative, molte coperte da brevetti Rockford,
sono descritte in un'altra sezione di questo manuale.
DOVE POSIZIONARLO
Nel Bagagliaio
Montando l'amplificatore su una superficie in verticale con le alette direzionate
dall'alto verso il basso si garantirá un miglior raffreddamento dell'amplificatore.
Nell'abitacolo
Montare l'amplificatore nell'abitacolo si avrá un funzionamento regolare se si
garantisce un flusso d'aria sufficiente. Per l'installazione sotto un sedile, é
necessario avere uno spazio di almeno 3 cm attorno a tutto l'amplificatore.
Installazione
Per sicurezza, scollegare il polo negativo della batteria dell'auto prima di
iniziare l'installazione.
Terminale B+ (cavo positivo)
Il cavo positivo deve essere protetto da un fusibile a non piú di 45 cm dalla
batteria. Terminare il cavo e installare il fusibile nel vano motore. Tutte le
connessioni devono essere a prova d'acqua.

Terminale GND (cavo negativo)
Deciderela lunghezza delcavoeterminarlo. Prepararela massa grattando
la vernice dal telaio dell'auto ed eliminando tracce di olio o sporco. Fissare
il cavo di massa al telaio con una vite.
Terminale REM (Consenso di accensione)
Collegare il cavo REM ad un positivo presente solo ad autoradio accesa
(normalmente il cavo pilota dell'antenna elettrica o il cavo accessori
dell'autoradio). Se la sorgente non dovesse essere equipaggiata con
queste uscite, la soluzione raccomandabile é di inserire un interruttore su
un cavo positivo e connettersi all'amplificatore.
