Loud enough to rock your entire basement block, the Alpine MRP-M450 Mono Amplifier amplifies sound levels up to 400 Watts RMS over a single channel. Bridge two similar amplifiers, and experience 600 Watts RMS of louder, clearer music. The amplifier maintains optimum temperature during its operation with the help of the Thermal Management Processor along with the MOSFET-based Power Supply. The incorporated Bass Engine Sound Tuning has a unique Subsonic Filter module that processes fixed 15 Hz frequency bass sounds. Its Bass EQ Frequency boosts the low frequency output of the amplifier from 0 dB (flat) to +12dB. In addition, it allows you to adjust the Bass EQ (centered a 50 Hz) to suit your personal taste. The Selectable and Adjustable Crossover splits sound frequencies up to 200 Hz at 24dB to create crystal clear sound.

The Auto Over-Current Protection system regulates the voltage between the alternator and the speakers, and prolongs these components’ life. The unique Gold Plated RCA Input Connectors eliminate any cable-borne interference. The Gain Control automatically regulates fluctuations in sound playback levels. The elegant Gold Plated Power Screw Terminals and Speaker Terminals offer reduce unwanted signal noise transmissions through the cables and connectors. It measures 9-11/16" x 2-23/64" x 9-31/64" and weighs 6.1 lbs.
