JL Audio MHD900/5-24V : 5ch 24V Marine Amplifier, 100W x 4 + 500W Mono @ 1.5-4Ω
MHD-Series 5-Channel Class-D 24-Volt Marine Grade Amplifier, 100-Watts x 4ch + 500-Watt Mono @ 1.5-4Ω
Thanks to its ability to act as a “one-box solution”, the MHD900/5-24V 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… with a very serious 900 watts of power!
Using JL Audio’s Single Cycle Control switching design and R.I.P.S technology, the MHD900/5-24V delivers 100W x 4ch 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.
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 24V may result in damage to the product and will void the warranty.
