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. The MHD600/4 – 24 V 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. This amplifier is designed for operation in vessels with 24 V, negative ground electrical systems. Use of this product in vessels with positive ground and/or voltages other than 24 V may result in damage to the product and will void the warranty.
