Description
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.
