Dear Customer, Congratulations on your purchase of the world's finest brand of car audio amplifiers. At Rockford Fosgate we are fanatics about musical reproduction at its best, and we are pleased you chose our product.
T ABLE OF C ONTENTS Introduction ................................................................................................ 1 Punch Amplifier Accessory Pack ................................................................... 1 Technical Design Features .
I NTRODUCTION Rockford engineers designed the Punch 55. 2 , 75. 2 , 125. 2 and 225. 2 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 circuit in the preamp stage of all Punch .
T ECHNICAL D ESIGN F EA TURES – 2 – ◆ T RANS•ANA ( TRANSconductance Active Nodal Amplifier) The TRANS•ANA ( TRANS conductance A ctive N odal A mplifier) is a circuit that allows the audio signal to pass through the amplifier at low voltage.
◆ DSM (Discrete Surface Mount) Technology The DSM (Discrete Surface Mount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process.
◆ MOSFET Devices Rockford Fosgate is one of the few manufacturers in the sound community to utilize MOSFET devices in both the power supply and the output stages . MOSFET ( M etal O xide S emiconductor F ield E ffect T ransistor) devices offer several important inherent advantages over the 30 year old technology of bi- polar design.
D ESIGN F EA TURES 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.
7. Input Sensitivity Controls – The input level controls are preset to match the output of most source units. They can be adjusted to match output levels from a variety of source units. 8. Punch Equalization Controls – The Punch EQ helps correct for acoustical deficiencies in the listening environment.
I NST ALLA TION C ONSIDERA TIONS The following is a list of tools you will need for installing the Punch amplifier: Allen wrenches 9/64" & 3/32" (included) Voltmeter Wire strippers Battery post wrench Electric hand drill w/assorted bits Wire cutters 17' (518.
M OUNTING L OCA TION 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 generated over a wide range of operating conditions.
B A TTERY AND C HARGING – 9 – 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.

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.
U SING P ASSIVE C ROSSOVERS 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.
