Marine Subwoofer Amplifier

The Pioneer GM-ME300X1C is a single-channel Class-D marine amplifier built for boats, ATVs, UTVs, and motorcycles. It delivers 75 watts RMS into a 4-ohm load with an IP67 weatherproof rating. SAE J1171 ignition protection and ABYC/NMMA certification make it safe for enclosed engine compartments. A rotatable badge keeps the logo upright in any mounting orientation.

Build Integration

The compact chassis fits tight spaces and uses a waterproof detachable connector for secure wiring. Top-mounted controls provide easy access to a variable low-pass filter with 21-step frequency selection and bass boost settings of 0, 6, or 12 dB. A microcomputer-controlled Protection Control System monitors internal temperature and automatically moderates input levels to prevent thermal shutdown during extended use.

Upgrade Context

This amplifier replaces lower-powered marine receivers or basic amplifiers that cannot drive a subwoofer clearly over wind, wave, and engine noise. The jump is worth it when you need dedicated mono power with certified ignition protection and a fully sealed IP67 enclosure. It is not suited for multi-channel speaker systems or installations requiring higher continuous RMS output than 75 watts.

Questions about this item

How much continuous power can the GM-ME300X1C deliver to a 4-ohm subwoofer before its protection circuit limits output?

The amplifier is rated for 75 watts RMS at 4 ohms; its Protection Control System monitors internal temperature and automatically reduces input level to prevent thermal shutdown during extended high-output use.

Does the IP67-rated chassis run silently and stay cool enough for all-day operation on a boat or ATV?

The Class-D design and compact IP67 enclosure have no fan; the built-in Protection Control System manages heat by moderating gain when temperatures rise, allowing continuous operation without audible cooling noise.

What power and signal connections must already be in place for this mono amplifier to function?

You need a 12 V DC supply with sufficient current capacity, a line-level RCA signal source, and a 4-ohm subwoofer; the unit includes a waterproof detachable power connector and RCA terminal covers for marine installation.
