Rockford Fosgate keeps making a good thing better with Punch amps and you'll find one for every type of car audio system, from mild to wild. Rockford Fosgate continues its commitment to outstanding design with the 4-channel Punch P450.4 amplifier. Specially-designed transistors perform better than the off-the-shelf models most manufacturers use. Additional heatsink material keeps these critical power components running cooler, reducing distortion and increasing amp efficiency. The P450.4 delivers plenty of power to drive both your front and rear speakers, or you can run it in 2-channel mode to send 550 watts total to a pair of subwoofers. The variable frequency filters adapt the amplifier to fit the job at hand, while the wired Punch Bass EQ kicks up the lows when it's time to get the car shaking.
