DESIGN FEATURES  
1. Cast Aluminum Heatsink The cast aluminum heatsink of the Punch 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. Variable Crossover The amplifiers have a built-in 12dB/octave Butterworth filter with a  
crossover point variable from 50Hz to 210Hz. The crossover can be set to Low-Pass (LP) or it  
can be bypassed by setting it to All-Pass (AP).  
3. 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.  
4. 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.  
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. High Level Inputs The high level inputs use a detachable connector terminated with 20 AWG  
leads. These inputs should be used if the source unit has only speaker line (high level) outputs  
and not RCA outputs.  
9. 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 switchable from 0dB to +6dB to +12dB.  
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 component 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 system. 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 amplifier.  
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.

INSTALLATION  
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.  
CAUTION: These amplifiers are not recommended for impedance loads below 2.

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 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 (capacitors), Low-Pass (inductors  
or coils) and Bandpass (combination of  
capacitor and coil).

Speaker Impedance  
Freq.  
Hertz  
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.

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 inaudible. 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  
50-210Hz.  
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 connections 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 including distributor, spark plugs, spark plug wires, voltage regulator etc.
