About the Alpine MRP-F320

High-quality Alpine power in an affordable amplifier! Alpine uses the same premium quality and engineering that it puts into its V12 amplifiers to make the V-Power amps.

High-quality Alpine power in an affordable amplifier! Alpine uses the same premium quality and engineering that it puts into its V12 amplifiers to make the V-Power amps. With a rugged look and high-tech features, the V-Power series has an amplifier for nearly any need — the MRP-F320 is a five channel power-pack that can amplify not only your speakers, but a subwoofer too.

Turn on the tuned Bass EQ for an 8 dB boost at 50 Hz to enhance the bass output. The speaker-level inputs let you add one of these amps to any car stereo.

Features

5 Channel: This amp is designed to power a four channel speaker system plus a subwoofer. There are front and rear inputs which are summed to create the subwoofer channel.

Crossover: The internal crossovers for channels 1 & 2 and channels 3 & 4 are 18dB/octave fixed at 80Hz. They can be set for high-pass or full range operation. There are separate crossovers for channels 1 & 2 and channels 3 & 4. The subwoofer crossover is variable from 50 to 200 Hz and is always engaged.

Speaker Level input: There is a four channel speaker level input harness compatible with nearly any model head unit, factory or aftermarket.

Multi Mode: A subwoofer and two stereo speakers can be powered simultaneously by each set of amplifier channels using Alpine's Multi Mode. An outboard crossover (or two) is required for this and is not included.

MOSFET Power Supply: The DC-DC converter uses MOSFETs for more efficient operation.

Bass Boost: The bass boost circuit is applied to the subwoofer channel. The boost is 8dB at 50 Hz.
