Alpine MRP-T222

It’s no accident that the V-Power line are the top-selling amplifiers in the US. They deliver robust power and offer outstanding flexibility for adding speakers and subs.

If you like your bass deep, tight and powerful, choose either of the mono amps and add some Type-S subs. These Class-D digital powerhouses are awesomely efficient. For greater flexibility, the 4/3/2-channel amps let you configure your system just the way you want it.

• The best performance within your budget.
• Built-in crossover, bass EQ and subsonic filter.
• High power output with outstanding flexibility for adding speakers and subwoofers.
• Customise system sound with Adjustable Bass EQ,Crossover and Subsonic Filter.
• Connect directly to factory-installed head units that don’t have preamp outputs.
• Enjoy cleaner bass due to the subsonic filter.
• Neat,compact design.

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 four-channel amp has independent RCA inputs for each channel. Internally, these are summed for the right and left signals to provide non-fading outputs for applications such as a separate subwoofer amp.

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.

These terminals allow direct connection to factoryinstalled head units that don’t have preamp outputs, letting you add subwoofers to any system.

This processing circuit provides optimum low frequency response, letting you adjust the bass for maximum clarity.

The rugged, road-worthy V-Power 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.
