Product details
Compact Class-D marine power
GM-ME300X4C delivers 75 W RMS per channel at 4 ohms or 2 ohms, with 150 W x 2 available when bridged at 4 ohms. CTA-2006 listing matches 75 W RMS x 4. The Class-D chassis measures just 9-5/8 x 1-7/8 x 4-1/8 inches and weighs 3.1 lb, so it fits tight consoles and under-seat cavities.

IPX7 / IP6X and SAE J1171 protection
With the control-panel cover installed, Pioneer rates the amp IPX7 waterproof and IP6X dustproof (self-certified). SAE J1171 certification covers ignition protection for marine engine compartments. A microcomputer Protection Control System watches voltage, current, and temperature to keep output stable on long runs.

Filters, inputs, and accessories
Independent A/B channel settings cover speaker mode, gain, and crossover. Variable HPF and LPF filters sweep 50 Hz to 500 Hz at −12 dB/oct. RCA and speaker-level inputs are supported. The carton includes a power cable, two speaker-line RCA input cables, a hex wrench, four 4 × 25 mm mounting screws, and a setup tool.
