Product details
Marine mono power with weather protection
GM-ME300X1C is built for boats and open vehicles: Class-D mono output at 300 W continuous into 4-ohm or 2-ohm loads, with an IPX7 / IP6X self-certified protection rating on the enclosure. The conformal approach and sealed connectors help the amp survive wet environments better than a standard car amplifier.

LPF tuning and compact marine chassis
A variable LPF from 20–240 Hz (−12 dB/oct) shapes the bass channel, and frequency response spans 10 Hz to 240 Hz. S/N is rated 100 dB (IHF-A). The chassis measures about 243 x 46.8 x 105 mm and weighs about 1.3 kg. A 30 A fuse protects the power section.

Install notes
Use marine-grade power, ground, and speaker wire with proper fusing at the battery. Mount away from direct spray when possible even with IP ratings. Match a marine bass speaker to the 300 W RMS continuous rating.

Important notes
- IP ratings are self-certified—still avoid prolonged submersion and direct high-pressure spray on connectors.
- Use marine-rated wire, fuse blocks, and bass speakers.
- Match the 300 W RMS continuous rating to your speaker's power handling.
- Provide a solid chassis ground and remote turn-on lead.
