Memphis Audio PRX800.5V2

The Memphis Audio PRX800.5V2 Power Reference is a five-channel car audio amplifier that powers four speaker channels and a separate subwoofer channel. At 2 ohms, Memphis lists 100 watts RMS by four plus 400 watts RMS for the subwoofer channel.

Variable crossovers, subsonic filtering, EQ boost and selectable turn-on support system setup. Top-mounted controls sit beneath the panel, with blue LED top and ground lighting. The aluminum chassis measures 10.1 by 5.7 by 2.16 inches, and Memphis recommends its 4GKIT wiring kit.

Match each speaker channel and the subwoofer load to the amplifier’s specified operating limits. Plan cable routing, fused power wiring, ventilation and access to the controls before installation.
