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 150 W x 2 to the satellites and 300 W 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.
