Rockford Fosgate Punch P500X1bd

Big power for your sub or sub system

Rockford Fosgate's Punch P500X1bd subwoofer amp can produce up to 500 watts RMS, giving you plenty of clean power for your rhythm track. And the P500X1bd can drive a 1-ohm load, so you can power multiple subs without any trouble. A low-pass filter keeps the high notes away from your sub, while a subsonic filter helps you rein in runaway boom. The Punch bass boost lets you add some of that boom back into the mix when it's needed.

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: 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.
