Rockford Fosgate P400X4 Punch 400-Watt 4-Channel Amplifier

Product description

System Versatility & Unmatched Performance

P400X4

The Punch P400X4 is a 4-channel amplifier producing 100 Watts into all four channels at 2-Ohm. The P400X4 is perfect for a 4-way full-range system or a 3-way system having a front stage with subwoofers on the rear channels.

The stealth top mounted control panel not only provides a sleek finished look to the amp, but it also protects the vital controls.

Our custom heat sink design uses high aluminum mass where it is needed most to maximize heat transfer from the output MOSFETS to the surrounding air, keeping the circuitry cool even under high power and output demand.

Punch 400-Watt Full-Range 4-Channel Amplifier Rated Power: 50 Watts x 4 @ 4-Ohm OR 100 Watts x 4 @ 2-Ohm OR 200 Watts x 2 @ 4-Ohm Bridged 12dB/octave Butterworth crossover Power Wire Gauge: 8 AWG to 4 AWG Speaker Wire Gauge: 8 AWG to 18 AWG Recommended Fuse (not included): 60 A Dimensions (H x W x D): 2.38″ x 7.76″ x 11.03″

C.L.E.A.N. Set-Up

C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is our patented circuit with in/out clip LEDs to help match a source to amp and optimize output

Punch EQ

Delivers more bass where you want it most by allowing up to 18dB of boost adjustment at 45Hz

Multi-Signal Inputs
