Rockford Fosgate P400X4 Punch 400 Watt 4-Channel Amplifier

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. Simply drop a pair of component speakers on the front channels and subs on the rear and BOOM – you got “The PUNCH.” With its flexible design, the P400X4 is an excellent amplifier choice for virtually any vehicle.

Big power for your speakers or subwoofers

Rockford Fosgate’s Punch P400X4 amplifier can put out 50 watts RMS to each of your front and rear speakers, plenty of power for clean music even at high levels. You can use the amp’s high-pass filter to remove low bass from your speakers so they’ll play more efficiently. You can also switch this amp into 2-channel mode to drive a couple of subwoofers with up to 200 watts RMS each. The amp’s low-pass filter comes in handy for getting the right sound from your sub/enclosure combo. The Punch EQ2 includes bass and treble boosts, in case you want to add some boom and sizzle back into the mix.

Easy to set for optimum performance

Once again, Rockford Fosgate steps away from the crowd with their C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) — a setup system that ensures your music will sound as clean and powerful as possible. It works like this: play the setup tone downloaded from Rockford Fosgate (download file of choice), adjust the receiver volume until a red clip light on the amp goes out, then turn the amp gain up until a blue light comes on. It’s that simple — your amplifier is now set to match your receiver’s output. When your receiver reaches maximum clean volume, you’ll get maximum clean power from your Punch amp. At quiet listening levels, you’ll hear less background noise and more of your music.

Keeps an eye on things while playing

If that blue light turns solid red while you’re playing music, the amp’s telling you that your source is distorting and you should turn it down, or risk damage to your gear. The amp’s built-in computer keeps tabs on the output current, ensuring that plunging speaker impedances (they change during play) or even a short circuit won’t hurt anything.

Maintaining coolness raises efficiency and lowers distortion

Rockford Fosgate’s Dynamic Thermal Management system uses forced air to dissipate heat evenly across the amp and out through the high-mass heatsink, efficiently drawing heat away from vital internal parts. Their proprietary MEHSA cooling process maximizes the heat transfer from the MOSFET devices to the heatsink, allowing the heat to escape more readily, so the transistors stay cooler and work better.
