MHD900/5

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 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.

Great Amp, Small Footprint

This thing is a BEAST! It fit behind the seat of my Super Crew with ease and my system sounds amazing! I wish I had a little more juice for my subs (2 10" W1s) at times but I do not regret this purchase one bit. I love the look of my clean install with this amp and did I mention it sounds amazing?!?! Absolutely NO white noise, no hum, just raw power. Worth every penny.

Best Amp I have ever owned!!!!

I have owned everything from Polk Audio, Alpine, Kicker and most recently a Pioneer amp all in different vehicles with different setups. I replaced the Pioneer amp with this JL. Install was a breeze as it comes with connectors for the all the wires. Hardest part was figuring out where to mount the amp in the boat. Great design. Great quality. Would recommend it to everyone. Yes it’s expensive but well worth it.
