Thanks to its ability to act as a "one-box solution", the MHD900/5-24 Volt is ideal for installations where space is at a premium and sound quality is the paramount goal.While extremely compact, this amazing amplifier will comfortably drive a complete high-performance marine audio system: that is, four satellite speaker systems and a subwoofer system. Using our single cycle control switching design and R.I.P.S technology, the MHD900/5-24 Volt delivers 100 Watt x 4 to its four main channels, plus a very meaty 500 Watt 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. This amplifier is designed for operation in vessels with 24 Volts, negative-ground electrical systems. Use of this product in vessels with positive ground and/or voltages other than 24 Volts may result in damage to the product and will void the warranty.
