Alpine MRP-T222 car audio amplifiers deliver exceptionally high performance and provide detailed control. Available in mono, two-channel and four-channel configurations, these amps are as powerful as they are versatile.

In multi-speaker systems, it is important to make sure each speaker is sent only those frequencies it is designed to reproduce. This built-in crossover removes overlapping frequencies, ensuring greater efficiency, less strain – and a louder, cleaner sound.

The power supply uses MOSFET circuitry to convert battery voltage to the voltages needed for high amplification. The result is higher power and much wider dynamic range.
