Thanks to its ability to act as a "one-box solution", the MHD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.While extremely compact, this amplifier will comfortably drive a complete high-performance marine audio system: that is, up to four satellite speaker systems and a subwoofer system with 900 watts of power.Using our Single Cycle Control switching design and R.I.P.S. technology, the MHD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500W to its subwoofer channel. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound quality.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.
