Introduction
Rockford engineers designed the Power series amplifiers to withstand the
rugged automotive environment while delivering superior sound quality in
a flexible, reliable, and efficient package. TRANS• ana is a low voltage cir-
cuit in the preamp stage 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 variable crossover. The use of a protection circuit called
NOMAD, along with MOSFET and DSM (Discrete Surface Mount) technol-
ogies improve amplifier efficiency. The result of these components give the
Power amplifier awesome sound quality in a “Bullet Proof” package.
Explanations of these technologies, most of which are exclusively designed
and patented by Rockford, are described in the Technical Design Features.
Power Amplifier Accessory Pack
The accessory pack shipped with the Power amplifiers includes the mount-
ing hardware necessary to secure the amp to the vehicle.

Design Features
1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Power amplifier
dissipates heat generated by the amplifier's circuitry. The inherent advantage of
casting provides a 30% improvement of cooling over conventional extrusion
heatsink designs.
2. Speaker/Power Terminals – The heavy duty, gold-plated terminal block con-
nectors (+ and –) will accept 4 gauge cable and are immune to corrosion that
can cause signal degradation.
3. REM Terminal – This spade terminal is used to remotely turn on and turn off the
amplifier when +12V DC is applied.
4. Signal Input Switch (Power 400, Power 800 4-channel & 600 5–channel
amplifiers) – This switch allows the amplifier to be driven with either 2 or 4
pairs of inputs.
5. RCA Input Jacks – The industry standard RCA jacks provide an easy connection
for signal level input. They are gold-plated to resist the signal degradation
caused by corrosion.
6. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-
chaining an additional amplifier without running an extra set of RCA cables
from the front of the vehicle to the rear amplifier location.
7. Gain Control – The input gain control is preset to match the output of most
source units. It can be adjusted to match output levels from a variety of source
units.
8. Remote Punch Bass – The Punch Bass helps correct for acoustical deficiencies
in the listening environment by helping reproduce full range sound without
adding excessive boost. The Punch Bass control is a narrow band adjustment
centered at 45Hz variable from 0dB to +18dB. Connection is made with a
cable using RJ-45 and can be installed under the dash for remote control access.
9. Internal Crossover – The internal crossover is a 24dB/octave Butterworth filter
selectable for High-Pass (HP), Full Range (FULL), or Low-Pass (LP) operation
variable from 50Hz to 210Hz.
10. LED Power Indicator – The LED illuminates when the unit is turned on.
11. Phase Warp (Power 1000 2-channel amplifier) – The phase warp is a variable
control used to adjust the phase of the output signal relative to the phase of the
input signal. The phase warp is most noticable when the system is playing a
sine wave (test tone). When used with the proper test equipment, this feature
can increase the relative SPL in a system.

Installation Considerations
This is a list of tools you will need for installing the Power amplifier:
• Voltmeter
• Wire strippers
• Electric hand drill w/assorted bits
• 17' (5 m) Red Power Wire
• 12' (4 m) Remote Turn-On Wire
• 1.5' (45 cm) Black Grounding Wire
• Battery post wrench
• Wire cutters
• Assorted connectors
• Wire crimpers
This section focuses on some of the vehicle considerations for installing
your new Power amplifier. Checking your battery and present sound sys-
tem, 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
attempting to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior to begin-
ning 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 plas-
tic 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 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.

Mounting Location
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 gen-
erated 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 com-
partment. Not only will this void your warranty but could create an embar-
rassing situation caused by the ridicule from your friends.

Battery and Charging
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.
Wiring the System
CAUTION: Avoid running power wires near the low level input cables, antenna,
power leads, sensitive equipment or harnesses. The power wires carry sub-
stantial current and could induce noise into the audio system.
1. 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 pre-
vent short circuits. Leave the wires long at this point to adjust for a pre-
cise fit at a later time.
2. Prepare the Power cable for attachment
INSULATION
STRIP WIRE
to the amplifier by stripping 5/8" of insu-
lation from the end of the wire. The use
of 8 gauge power cable can interfere
with the installation of the end caps.
Proper wire dress can prevent this from
occurring. To prevent the wire from fray-
ing, strip the insulation at a 45° angle.
Insert the bared wire into the B+ terminal
<
>
5/8"
AMP
with the long side of the insulation on the top. Bend the cable down at
a 90° angle. Tighten the set screw to secure the cable in place.
3. 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.

4. 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 above and
connect to the appropriate terminal of the amplifier. Prepare the chas-
sis ground by scraping any paint from the metal surface and thorough-
ly 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.
5. Prepare the REM turn-on wire for connection to the amplifier by strip-
ping 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 mechanical switch in line with a 12 volt source to activate the ampli-
fier.
6. Securely mount the amplifier (with supplied screws) to the vehicle or
amp rack. Be careful not to mount the amplifier on cardboard or plas-
tic panels. Doing so may enable the screws to pull out from the panel
due to road vibrations or sudden vehicle stops.
7. Determine the number of inputs needed to drive the amplifier and
move the input switch to the desired setting (Power 400 & Power 800
4-channel amplifiers only.).
8. Connect the source signal to the amplifier by plugging the RCA cables
into the input jack(s) at the amplifier.
9. Connect the speakers. Strip the speaker wires 5/8" and insert into the
appropriate terminal on the amplifier. 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 from
road vibrations.

Using Passive Crossovers
+-
A passive crossover is a circuit that uses capacitors and/or coils
and is placed on speaker leads between the amplifier and speak-
er. 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 (capacitors), Low-Pass (inductors or coils) and
Bandpass (combination of capacitor and coil).
The most commonly used passive crossover networks are 6dB/octave sys-
tems. These are easy to construct and require one component per filter.
Placing this filter in series with the circuit will reduce power to the speak-
er 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 profes-
sionally 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 Power
amplifiers are not recommended for impedance loads below 2Ω stereo
and 4Ω bridged (mono) loads.

Phase Warp
2-channel
The Phase Warp is a variable control used to adjust the phase of the out-
put signal relative to the phase of the input signal. This "phase alignment"
is most noticable when used with an array of woofers whose vertical or
horizontal planes are staggered (not eminating from the same point.)
Adjusting the Phase Warp can electrically realign the signal fed to each
woofer as if all woofers were aligned on a common ZDP. In SPL systems,
a desired ZDP (Zero Delay Plane) is the point source where all speaker's
voice coils are aligned on the same imaginary plane, thus allowing the
signals to arrive at the microphone at the same time.
The phase warp is most noticable when the system is playing a sine wave
(test tone), not music. When used with the proper test equipment, this
feature can increase the relative SPL in a system.
If the Phase Warp is not used (like with a competitive SPL vehicle,) each
amplifier's Phase Warp should be set to (0˚) or (-).
All waveforms are ”phase aligned” at
the targeted microphone position

If you are having problems after installation follow the
Troubleshooting procedures below.
Procedure 1: Check Amplifier for proper connections.
Verify that POWER light is on. If POWER light is on skip to Step 2, if not
continue.
1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal of the vehi-
cle’s chassis. Repair/replace if necessary.
3. Verify there is 10.5 - 15.5 Volts of current present at the positive battery
and remote turn-on cable. Verify quality connections for both cables at
amplifier, stereo, and battery/fuseholder. Repair/replace if necessary.
Procedure 2: Check Amplifier for audio output.
1. Connect a single 4 or 8 ohm test speaker directly to each output chan-
nel amplifier. Verify speakers in car are good and wiring between
amplifier and speakers, including connectors are good. Repair/replace
if necessary.
2. Verify good RCA/high-level input connections at stereo and amplifier.
Check entire length of cables for kinks, splices, etc. Test RCA/high-level
inputs for AC current with stereo on. Repair/replace if necessary.
3. Disconnect RCA/high-level input from amplifier. Connect RCA/high-
level input from test stereo directly to amplifier input.
Procedure 3: Check Amplifier if you experience Turn-on Pop.
1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REM lead of amplifier to source
unit with a delay turn-on module.
OR
1. Use a different 12 Volt source for REM lead of amplifier (i.e. battery
direct).
2. If the noise is eliminated, use a relay to isolate the amplifier from noisy
turn-on output.

Dynamic Power Measurements
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% dis-
tortion. 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) is
fixed. A loudspeaker's impedance is dynamic. It is constantly changing in value,
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 nom-
inal (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 (voice
coil) and a capacitor (compliance of the surround/spider), as well 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 imped-
ances 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 Amplifier PowerCube
What is an Amplifier?
An amplifier by definition is a voltage generating device, recreating the sig-
nal which is input to it identically but with increased volume. It will be con-
nected 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 volt-
age regardless of load characteristics and will not alter the signal it is repro-
ducing. 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!

ATTENTION: Veuillez lire les instructions suivantes pour l'installation de cet
amplificateur. Ne pas les suivre pourrait causer des blessures ou endommager
le véhicule.
Introduction
Les ingénieurs de Rockford Fosgate ont conçu l'amplificateur Power pour
supporter l'environnement rude de l'automobile en délivrant une qualité de
son supérieure dans un ensemble efficace, fiable et flexible.
Trans• ana/Trans• nova est un circuit de bas voltage dans l'étage de préam-
plification de tous les amplificateurs Punch 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 pour éliminer les prob-
lèmes de bruits parasites associés aux systémes audiomobile et leur instal-
lation.
La fiabilité est garantie grâce au circuit de protection NOMAD, la tech-
nologie MOSFET et DSM (Composants Montés en Surface) améliorent l'ef-
ficacité de l'amplificateur.
L'ensemble de ces atouts donne à l'amplificateur Power une qualité de son
inégalable sous une carrosserie “pare-balles.”
Montage
Montage dans le coffre
Monter l'amplificateur verticalement avec les rainures de haut en bas ce qui
lui permet de refroidir plus facilement.
Montage dans l'habitacle
Monter l'amplificateur dans l'habitacle ne pose aucun problème, du
moment qu'il y ait assez d'air pour le refroidir. Si vous montez l'ampli en
dessous du siège, prévoyez 2.5 cm d'air autour du radiateur.
Installation
Pour votre sécurité, déconnectez la borne négative de la batterie du
véhicule avant de commencer l'installation.
Terminal B+
Il est impératif qu'il y ait un fusible sur le câble pour la connexion à la
masse. Préparez le châssis en grattant la peinture de la surface métallique et
nettoyez la saleté et l'huile. Attachez le câble au châssis avec une vis.

Einleitung
Rockford Ingenieure haben die Power Verstärker entwickelt. Mit höchstem
Technologie-Standart,
hervorragender
Klangqualität,
einfacher
Handhabung und bester Servicefreundlichkeit Trans• ana/Trans• nova ist
eine Nieder-Volt Schaltung im Vorverstärkerteil aller Pünch 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 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 Power-Verstärker so einzi-
gartig und in ihrer Klangqualität nahezu unschlagbar.

oben nach unten verlaufen, gibt dem Verstärker die beste Kühlung.
Auf der Beifahrerseite
Sollte der Verstärker auf der Beifahrerseite montiert werden, so ist es sehr
wichtig, für eine ausreichende Kühlung zu sorgen. Sollte der Verstärker z.B.
unter dem Beifahrersitz montiert werden, sollte dem Kühlkörper mindestens
ein Luftspalt von 2.5 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+ Anschlub
Die Plus-Leitung MUb ca. 45 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 Anschlub
Preparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). Preparieren Sie
die Anschlubstelle des Erdungskabels, indem Sie das Metall gründlich reini-
gen und vom Lack befreien. Befestigen Sie nun die Erdung an dieser Stelle
mit einer Schraube.
REM Anschlub
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.

ATTENZIONE: SI PREGA DI LEGGERE LE SEGUENTI ISTRUZIONI PER L'INSTAL-
LAZIONE DI QUESTO PRODOTTO. IL NON SEGUIRLE POTREBBE RISULTARE SERI-
AMENTE DANNOSO PER LA PERSONA O PER IL VEICOLO.
Introduzione
Gli ingenieri Rockford hanno progettato la serie di amplificatori Power per
resistere all'ostico ambiente automobilistico mentre suonano con una musi-
calitá superiore, offrendo un insieme versatile, affidabile ed efficiente.
Trans• ana/Trans• nova é un circuito a bassa tensione dello stadio preampli-
ficatore del Punch 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. L'affidabilitá é completa-
mente 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 Power
suonano meravigliosamente e sono indistruttibili, a “prova di proiettile.”
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 2.5 cm attorno a tutto l'amplifica-
tore.
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.

ITALIANO
Terminale GND (cavo negativo)
Decidere la lunghezza del cavo e terminarlo. Preparare la 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 del-
l'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.
