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. If you do choose to install the amplifier yourself, please be sure to read the entire manual before begin- ning. Features The Rockford Fosgate 4-Channel automotive stereo power and amplif

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. To get a better understanding of the Punch let’s take a closer look. CONTROLS AND FEATURES This section describes the various controls and features of the Punch 4040 DSM and 4080 DSM amplifiers.

4. 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. 5. For safety, disconnect the battery ground cable prior to beginning the installation process. 6. Never run wires underneath the vehicle. The cleanest, safest wiring connections are made by running the wire under the carpet or behind the side panels. Never leave wires exposed. 7. Avoid running wires over or through sharp

MOUNTING AND LOCATION 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. It is reasonably tolerant of mounting variations. However, care should be taken to ensure adequate ventilation. Trunk The temperature inside a trunk can reach as high as 175° Mounting F (80° C) during the

Speakers Punch 4-Channel amplifiers are rated for safe operation into loads of 2Ω , or greater in stereo mode or 4Ω 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 2Ω stereo or 4Ω bridged/mono. Bridged/Mono The Punch 4-Channel amplifiers are capable of bridged/ Configuration mono configurations. This configuration enables you to: • Run amplifier as a se

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 result, limiting the types of frequency to the speaker, is directly dependent upon the speaker’s impedance and component values. The most common filters used in speaker crossovers, a
