1. Cast Aluminum Heatsink The cast aluminum heatsink of the Punch amplifier dissipates heat generated by the amplifi-  
er's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion  
heatsink designs.  
2. 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.  
3. Variable Crossover The amplifiers have a built-in 12dB/octave Butterworth filter with a crossover point variable from  
50Hz to 250Hz. The crossover can be set to Low-Pass (LP) or it can be bypassed by setting it to Full Range (FULL).  
4. RCA Input Jacks The industry standard RCA jacks provide an easy connection for signal level input. They are gold-plat-  
ed to resist the signal degradation caused by corrosion.  
5. LED Power Indicator The LED illuminates when the unit is turned on.  
6. REM Terminal This spade terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.  
7. Power Terminals The power and ground connectors on the Punch amplifier are gold-plated and will accommodate up  
to 8 AWG wire maximizing the input current capability of the amplifier.  
8. Punch Bass The Punch Bass control helps correct for acoustical deficiencies in the listening environment by helping  
produce full range sound without adding excessive boost.. The Punch Bass control is a narrow band adjustment 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. 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.  
10. Speaker Terminals The heavy duty, gold-plated terminal block connectors (+ and ) will accept wire sizes from 8 AWG  
to 18 AWG. These gold-plated connectors are immune to corrosion that can cause signal deterioration.

INSTALLATION  
This section focuses on some of the vehicle considerations for installing your new Amplifier. Pre-planning your system layout  
and best wiring routes will save installation time. When deciding on the layout of your new system, be sure that each compo-  
nent will be easily accessible for making adjustments.  
CAUTION: If you feel unsure about installing this system yourself, have it installed by a qualified technician.  
!
!
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire  
and/or possible injury.  
Before beginning any installation, follow these simple rules:  
1. Be sure to carefully read and understand the instructions before attempting to install the Unit.  
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 Source Unit 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 the appropriate fuse holder and  
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 connections 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 LOCATIONS  
The mounting position of your amplified subwoofer will have a great effect on the sound performance produced.  
Engine Compartment  
Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void your warranty.  
Trunk Mounting  
Mounting the amplifier vertically 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.

INSTALLATION  
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 sys-  
tem. Stock electrical systems which are in good condition should be able to handle the extra load of any Rockford Fosgate  
amplifier without problems, although battery and alternator life can be reduced slightly. To maximize the performance of your  
amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor.  
WIRING THE SYSTEM  
CAUTION: If you do not feel comfortable with wiring your new unit, please see your local Authorized  
!
Rockford Fosgate Dealer for installation.  
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire  
!
and/or possible injury.  
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.  
1. Plan the wire routing. Keep RCA cables 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.  
2. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 1/2" of insulation from the end of the  
wire. Insert the bared wire into the B+ terminal and tighten the set screw to secure the cable in place.  
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.  
3. Trim the RED wire (power cable) within 18" of the battery and strip1/2"of insulation from the end of the wire. Cut the wire  
loop that is attached to the fuseholder in half and splice the fuse into the power line using appropriate inline connectors.  
Use the section of cable that was trimmed earlier and connect it to the other end of the fuseholder.  
4. Strip 1/2" 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 the BLACK wire (Ground cable) for attachment to the amplifier by stripping 1/2" of insulation from the end of the  
wire. Insert the bared wire into the GND terminal and tighten the set screw to secure the cable in place. 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 1/2" of insulation from the wire end. Insert the  
bared wire into the REM terminal and tighten the set screw to secure the cable into place. Connect the other end of the  
REM wire to a switched 12 volt positive source. The switched voltage is usually taken from the source unit's accessory  
lead. If the source unit does not have this output available, the recommended solution is to wire a mechanical switch in  
line with a 12 volt source to activate the amplifier.  
7. Securely mount the amplifier 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/high level inputs into the input jacks at the amplifi-  
er.  
9. Connect the speakers. Strip the speaker wires 1/2" and insert 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.  
NOTE: Follow the diagrams for proper signal polarity.

USING PASSIVE CROSSOVERS  
L
C
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 fre-  
quencies 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 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 com-  
plex systems such as 12dB/octave or 18dB/octave can  
cause impedance problems if not professionally designed.

Passive crossovers are directly dependent upon the speak-  
er'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.

OPERATION  
ADJUSTING GAIN  
To adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume up until distortion is audible  
and then turn it down a bit until the distortion is inaudible. This will be about two thirds all the way up on most source units.  
Next, turn the amplifier gain setting until once again distortion is audible and then back it down until the distortion is inaudi-  
ble. Rockford Fosgate source units do not distort, so the volume can be used at maximum setting.  
NOTE: For a more in depth setting procedure, contact Rockford Technical Support.  
ADJUSTING CROSSOVER FREQUENCY  
Placing the switch in the Full position sets the amplifier to the full range frequency mode, preventing any crossover  
adjustment.  
Placing the switch in the LP position allows the crossover frequency to be adjusted between 50-250Hz.  
Turn the crossover adjustment knob all the way down. With the system playing, turn the crossover adjustment knob up slowly  
until the desired crossover point is achieved.

TROUBLESHOOTING  
NOTE: 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 vehicles 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 connec-  
tions for both cables at amplifier, stereo, and battery/fuseholder. Repair/replace if necessary.  
Procedure 2: Check Amplifier for audio output.  
1. 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.  
2. 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.  
Procedure 4: Check Amplifier if you experience excess Engine Noise.  
1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.  
OR  
2. Bypass any and all electrical components between the stereo and the amplifier(s). Connect stereo directly to input of  
amplifier. If noise goes away the unit being bypassed is the cause of the noise.  
OR  
3. Remove existing ground wires for all electrical components. Reground wires to different locations. Verify that grounding  
location is clean, shiny metal free of paint, rust etc.  
OR  
4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.  
OR  
5. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle electrical system includ-  
ing distributor, spark plugs, spark plug wires, voltage regulator etc.
