Outstanding audio performance — you expect it when the amp is an Alpine. Alpine's V-Power amplifiers supply the high level of performance you want without shaking loose too much of your hard-earned cash.

The MRP-M850 mono amplifier will power your subwoofer with 500 watts of power. Add a second sub and the MRP-M850 pumps out 800 watts — enough power for some seriously "good vibrations." The variable low-pass filter adjusts the frequency output to match your system, while the Bass EQ lets you dial in some extra boost on the lows. A subsonic filter eliminates inaudible, ultra-low bass notes for cleaner output.

The amp's machined-metal heatsink keeps the internal parts cool and distortion low even when you're cranking the volume. Gold-plated screw terminals and RCA connections resist corrosion that can degrade signal performance.

Features

Power Supply: The MRP-M850 amplifier's power supply uses MOSFETs to convert DC battery voltage to the higher DC voltages needed for high power. It supplies positive and negative voltages around 0V, rather than around 6V as with conventional single-polarity power supplies. The result is higher power levels and a dynamic range wider by as much as 10dB.

Low Pass Filter: The amp is equipped with a 50-200Hz variable low-pass filter with a slope of 24dB/octave. This being a mono subwoofer amp, the crossover is always engaged.

Subsonic Filter: This amp utilizes a 15Hz subsonic filter to eliminate super low frequencies that can rob power and damage speakers. The subsonic filter operates at all times, and cannot be turned off.

Bass EQ: The Bass EQ circuit provides a variable boost (0-12dB) at 50 Hz.

Inputs: The amplifier offers both line-level and speaker-level inputs for 2 channels. The supplied speaker-level input harness allows you to connect this amplifier to a receiver without preamp outputs; aftermarket or factory.

Terminal Covers: The amp comes with two plastic covers that protect and insulate the RCA, power, and speaker connections. Four supplied machine screws attach the covers to the amplifier.
