Our take on the Rockford Fosgate Power T500X1br

by Buck Pomerantz
Rockford Fosgate

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Super-compact, bursting with power

Rockford Fosgate's Power Series T500X1br mono amplifier can drive up to 500 watts RMS into a 1-ohm load, allowing you to power multiple subs to get more bass. A dual-fan forced air cooling system keeps this sturdy little amp from overheating, so it can play hard for a long time.

Boosted Rail amp technology

Boosted Rail (BR) amp technology uses capacitors and high-speed circuitry to boost the amp's power supply voltage, when needed, so it can handle massive musical peaks without missing a beat. Rockford Fosgate uses this technology to create a remarkable amp that fits almost anywhere and delivers powerful sound.

Easy to set for optimum performance

Rockford Fosgate's C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) setup system ensures your music will sound as clean and powerful as possible. It works like this: play the setup tone on the included test CD, 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.

Clip lights

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.
