Craving high-performance audio while cruising on open water? The MHD750/1 Marine Amplifier from JL Audio delivers unmatched power in a compact, weather-resistant design. With robust Class D technology, this amplifier keeps your system pumping clean and distortion-free sound—even in harsh marine environments.
Engineered specifically for marine use, this single-channel amp packs 750 watts of RMS power. That means it’s ideal for driving subwoofers or powering a dedicated audio zone on your boat with full control and precision.With unmatched performance and marine-specific engineering, the MHD750/1 ensures your sound system stays powerful and clear. It’s a premium amplifier made for boating enthusiasts who demand the best.
The MHD750/1 uses JL Audio’s patented NexD™ switching technology. This enables high-speed switching and efficient output with minimal heat. Unlike bulky traditional amps, this model remains small and efficient without sacrificing punch.
It delivers:
750 watts x 1 at 1.5–4 ohms
Consistent thermal management
Efficient use of onboard battery power
You get the clean power you need to push marine subwoofers or multiple speakers with zero distortion.
Saltwater, spray, and sun take a toll on electronics. But not this amp. The MHD750/1 features:
Corrosion-resistant aluminum chassis
Conformal-coated circuit boards
Stainless-steel hardware
This marine amplifier is made to survive and thrive in humid, wet, and UV-heavy conditions. JL Audio tests each unit rigorously to ensure reliable marine performance.
Don’t worry about matching systems or configurations. The MHD750/1 works across multiple impedance loads and integrates easily with other JL Audio gear. You can:
Combine with MHD600/4 for a full-range setup
Add a marine equalizer for fine tuning
Use high-level or low-level inputs
Built-in low-pass filters and signal processing give you control over your audio zones and sound shaping.
The amp’s compact footprint lets it mount under seats, in consoles, or near battery compartments. It features marine-grade connections for:
Power
Ground
Remote turn-on
Speaker and input wiring
The included mounting brackets and sealing gaskets make waterproofing and vibration-damping simple. No marine job is too tight for this versatile design.
This amplifier pairs beautifully with JL Audio’s full line of marine amplifiers collection and marine subwoofers. Whether you’re outfitting a center console or a luxury yacht, the MHD750/1 is a powerful, efficient solution.
And if you want even better protection for your sound system, consider adding marine window tinting.
Prolong your system’s lifespan and protect your gear from sun damage. Window tint blocks harmful UV rays, reduces cabin heat, and prevents audio equipment from overheating.

I did receive my package in only a few days which was great. I have opened it and it is the complete kit. Hopefully when I have it installed it works as expected. If so it will have been a great shopping experience with, Audio Jam.
