About the Rockford Fosgate T400X4AD: Compact 4-Channel Car Amplifier

Super-compact, bursting through power:

Rockford Fosgate's power series T400X4AD 4-Channel Amplifier can send up to 100 W RMS to four separate speakers, or you could use this tiny powerpack to run a couple of subs 200 W each.  A dual fan forced air cooling system keeps this sturdy little amp from overheating, so it can play hard for a long time.

Class-AD: accurate and powerful:

Rockford Fosgate uses their proprietary Class-AD Amplifier technology, combining the high fidelity of a Class-A system through the high efficiency of their special Class-D technology, to bring you this ultra-efficient, high-output amplifier. In other words, this compact amp produces more power with less current draw from your vehicle's charging system than most other amps on the road today.

Rockford Fosgate's high tech solutions yield more power:

Power series Amplifiers actively monitor speaker performance using Rockford Fosgate's constant power technology.  A speaker's impedance naturally fluctuates as it performs, fighting against your amp's output.  So, just like your cruise control increases the engine's RPM to maintain your car's speed uphill, constant power maintains this amp's output by increasing its internal voltage and current flow when the speaker's impedance rises.  This results in up to a 25% increase in the amp's total power output.

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: 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.

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.
