Marine Grade

MHD-Series 4-Channel Class-D Marine Grade Amplifier, 150-Watts x 4ch @ 1.5-4-Ohms This compact, multi-channel powerhouse employs JL's Single-Cycle Control switching design and R.I.P.S. technology to deliver 150W x 4ch or 300W x 2ch. 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.

MHD-Series 4-Channel Class-D 24-Volt Marine Grade Amplifier, 150-Watts x 4ch @ 1.5-4-Ohms This compact, multi-channel powerhouse employs JL's Single-Cycle Control switching design and R.I.P.S. technology to deliver 150W x 4ch or 300W x 2ch's. Tight power supply regulation keeps distortion down and maximizes sound quality. The MHD600/4-24V 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 2ch 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. This amplifier is designed for operation in vessels with 24 volt, 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.
