Rockford Fosgate Power T400X2ad 2-Channel Amplifier
Rockford Fosgate's Power Series T400X2ad 2-channel amplifier can send each of your speakers up to 200 watts RMS, or you can use this tiny powerpack to run a sub with up to 400 watts. A dual-fan forced air cooling system keeps this sturdy little amp from overheating, so it can play hard for a long, 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 with 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.
Setting it up 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.
