Don't let your sound system dance around the ring; fire up a 4-channel Punch series amplifier from Rockford Fosgate and enjoy a knockout performance every time! These amps will sting your speakers with plenty of clean power, while serving up the sound-shaping controls and high-quality components you need to create a heavyweight audio system.

Slam your speakers with a one-two combination of power and control with the Punch P4004 amplifier! With its innovative circuit design, MOSFET output stages, and proprietary technology, the P4004 will bring out extraordinary detail in your music, with ultra-clean power you just can't get from a lesser amp. You get 50 watts RMS by four channels to power two sets of full-range or component speakers — or you can bridge the P4004 for 200 watts RMS x 2 for a pair of subs.

The audio fanatics at Rockford Fosgate know that it takes more than just muscle to create a prize-winning car audio system. That's why the P4004 is equipped with variable high- and low-pass crossovers — which minimize distortion by sending your speakers only the frequencies that they can handle — and a Punch bass boost (0-18 dB at 45 Hz) with a wired remote for hands-on control. You choose the right settings for your car, your speakers, and your ears.
