MHD600/4

4-Channel Class D Marine Full-Range Amplifier, 150 W x 4 @ 1.5-4 O

This compact, multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.

When using the MHD750/1 to drive a subwoofer system, the MHD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. It can also be deployed, on its own, as a very capable 3-channel system amplifier with 150W x 2 to the satellites and 300W x 1 to a subwoofer system.

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.
