Dear Customer, Congratulations on your purchase of the world's finest brand of car audio amplifiers. At Rockford Fosgate we are committed to musical reproduction at its best, and we are pleased you chose our product.
T ABLE OF C ONTENTS Introduction ...................................................................................... 1 Punch 4-Channel Amplifier Accessory Pack ...................................... 1 Rockford Fosgate Accessories ..................
I NTRODUCTION The Punch 160x 4 and 240x 4 are 4-channel amplifiers which can deliver 160 watts and 240 watts RMS respectively. Both ampli- fiers utilize a 2/4-channel input switch to eliminate the need for signal splitters.
R OCKFORD F OSGA TE A CCESSORIES The following accessories were designed to enhance the perfor- mance of the Punch 160x 4 and 240x 4 amplifiers. Energy Storage Capacitor The Punch capacitors are used to provide extra current needed by amplifiers to reproduce musical transients.
T ECHNICAL D ESIGN F EA TURES – 3 – ◆ T RANS•ANA ( T RANSconductance Active Nodal Amplifier) The TRANS • ANA ( T RANSconductance Active Nodal Amplifier) 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 com- bines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manu- facturer to have invested millions into this process.
◆ RTP (Real Time Protection) NOMAD (NOn-Multiplying Advanced Decision) The Punch and Power amplifiers use an analog computer process to maximize safe output power under all operating conditions. Rock- ford Fosgate pioneered and developed RTP (Real Time Protection), a crucial element in the performance edge of our amplifiers.
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.
6. RCA Input Jacks – The industry standard RCA jacks provide easy connections for signal level input. They are gold-plated to resist the signal degradation caused by corrosion. 7. Signal Input Switch – This switch allows selection of 2-channel or 4-channel source unit feed.
I NST ALLA TION C ONSIDERA TIONS This section focuses on some of the vehicle considerations for installing your new Punch amplifier. Checking your battery and present sound system, as well as pre-planning your system layout and best wiring routes will save installation time.
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 condi- tions.
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.
3. Punch 160x 4 Trim the power cable to within 18" of the battery and install the protective rubber boot packed with the fuseholder over the end of the wire. Strip 3/8" of insulation from the wire and insert it into the end of the fuseholder, then crimp it in place.
6. Prepare the REM turn-on wire for connection to the amplifier by stripping 5/8" of insulation from the wire end and crimping an insulated spade connector in place. Slide the connector over the REM terminal on the amplifier. Connect the other end of the REM wire to a switched 12 volt positive source.
U SING THE XC ARD The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. Each crossover card has two faces: one face operates Full Range , the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low-pass) operation.
