Rockford Fosgate P300X1: Punch Mono Amplifier

P300X2 control panel shown as example

Once again, Rockford Fosgate steps away from the crowd through 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: first download the setup tones from Rockford Fosgate, then play the tone, 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 will be perfectly set to match your receiver's output.  When your receiver reaches maximum clean volume, you'll get maximum clean power from your power 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 optional PLC2 remote level control also doubles as a clip indicator, so you can see from the front seat if your music's clipping. 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.
