3-Channel Class D Marine System Amplifier, 75 W x 2 @ 4 + 300 W x 1 @ 2 - 14.4V


This compact amplifier is ideal for a simple audiophile-grade, subwoofer / satellite system. With the M500/3, you can drive a pair of quality component speaker systems with plenty of clean power, while also delivering a stout 300 W to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design.

The M500/3 includes a 12 dB / octave high-pass filter for its main channels, plus a variable slope low-pass filter for its subwoofer channel. Both filters offer continuously variable cutoff frequency selection from 50-500 Hz.

This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
