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 400x 4 (pronounced “ x4 ” not “ by 4 ” ) is a 4-channel amplifier which can deliver 400 watts RMS. This amplifier utilizes 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 400x 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 – ◆ TOP AZ (T racking Operation Pre-Amplifier Zone) The TOPAZ ( T racking O peration P re- A mplifier Z one) circuitry solves ground loop noise problems common to automotive amplifier design.
◆ 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.
◆ Pass-Thru Output The Pass-Thru output provides a convenient source for daisy- chaining an additional amplifier without the need for extra RCA cables or “ Y ” adapters. The Pass-Thru signal is derived from summing the Front and Rear Left inputs to create a Left output, and summing the Front and Rear Right inputs to create a Right output.
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. Signal Input Switch – This switch allows selection of 2-channel or 4-channel input. 8. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier location.
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. Mount the fuseholder within 18" of the battery using two (2) #8 screws. Disassemble the fuseholder. You should have 2 black plastic end caps, 2 gold-plated fuse clips, a plastic spacer and the fuseholder body. Trim the amplifier power cable to reach the fuseholder and strip the wire 3/8".
8. Connect the speakers. Strip the speaker wires 5/8" and insert into the appropriate terminal on the amplifier. Insert the bared wire into the speaker terminal and tighten the set screw to secure into place. Be sure to maintain proper speaker polarity.
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.
