4 INTRODUCTION This manual provides information on the features, instal- lation, and operation of the Punch 4040 DSM and 4080 DSM Amplifiers. We suggest you save this manual for future reference. We strongly recommend you have your Authorized Rock- ford Fosgate Dealer install your new Punch 4-channel amplifier.
5 Real Time Power Protection (R.T.P.P.) allows for the greatest power output under all load conditions. When output reaches an unsafe level it will be reduced, unlike current limiting which often causes premature protection or failure to protect at all.
6 B+/GND Power Connector LED Power Indicator REM Connector Four (4) custom, round, hex screws included in the acces- sory pack hold the unit in place. These screws are covered when the end caps are installed.
Input/Output Terminal Side 7 Front Treble Adjustment Control Front Bass Adjustment Control Front Input Gain Control Rear Treble Adjustment Control Rear Input Gain Control Rear Bass Adjustment Control This switch allows you to use the front input to drive both Front and Rear channels.
8 The amplifier ’ s signal input, female, RCA jacks should be connected to the source unit ’ s signal outputs with high- quality RCA cables. The connectors have been plated in gold to eliminate the possibility of corrosion that can cause signal deterioration.

MOUNTING AND LOCA TION The mounting location and position of the Punch 4- Channel will have a great effect on its ability to dissipate the heat generated in normal operation. The Punch 4- Channel has a heatsink designed for heat dissipation and internal shutoff circuitry to avoid overheating.
2. For the Punch 4040, place the protective boot onto the wire. Insert the wire into one end of the fuse holder so that the insulation is just inside the crimp area as shown in the diagram. Crimp the wire in place with the notched portion of a crimping tool.
12 Wiring the Ring and Spade Connectors 1. Strip back approximately 3/8" (1cm) of insulation. 2. Insert the bare wire into the connector and crimp in place as shown in the following diagram: 3/8" (1cm) { { Crimp Here Wire w/insulation Bare Wire Connectors Crimp Here This connector is used for the Red Power wire and Black Ground wire.
13 > < 5/8" INSULA TION STRIP WIRE > > AMP > The GND terminal grounds the amplifier and is con- nected to the chassis of the vehicle with 12 gauge, or heavier, stranded wire. When grounding, scrape paint off metal to ensure a good, clean ground connection.
14 Punch 4-Channel amplifiers are rated for safe operation into loads of 2 Ω , or greater in stereo mode or 4 Ω in bridged/mono configurations. The primary loads on any amplifier come from directly connected speakers without using capacitors. The measured resistance for each side should not be less than 2 Ω stereo or 4 Ω bridged/mono.
The most commonly used filter networks are 6 dB per octave systems. These are easy to construct and require a minimum number of parts. A filter network can perform one of three functions. These are highpass (capacitors), lowpass (inductors, chokes or coils) and bandpass (com- bination of a capacitor and a coil).

The Punch 4-Channel amplifiers feature selectable elec- tronic crossovers. Selection is made by positioning of a removable module card. These modules control the output channels and can be configured in a High Pass, Low Pass or Full Range (factory default) position.

Problem Amplifier will not play – Remote turn-on light is off. Solution 1. Check the DC voltage at the amplifier's B+ terminal with a voltmeter. The voltage should measure be- tween 11.5V - 15.5V. If voltage is not found, check the battery, fuse, fuse housing and wire connections.
26 Problem Amplifier gets too hot. Solution 1. Be sure the amplifier is properly mounted. You should be able to place your hand a few inches above the amplifier housing and feel the heat rising when the unit is on. Hot air rises, consequently, mount the amplifier with the heatsink fins aligned vertically.
Problem Engine Noise (Whine) Solution 1. Disconnect the speakers from the amplifier. Connect a test speaker to the amplifier output terminals. If the noise goes away, check your speaker leads, speakers and crossovers. 2. If the noise persists, use a "shorting plug" to mute the input signal at the amplifier.
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.
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.
30 What is an Amplifier? An amplifier by definition is a voltage generating device, recreating the signal which is input to in an identical but amplified form.
