Power your sub on water or land

There’s almost nothing cooler than bringing the beats while you’re out tearing it up off-road or on the water. JL Audio’s MX300/1 compact mono amplifier can send up to 300 watts RMS to your sub so you’ll enjoy your music’s thunderous power over all the noise of you having fun.


The MX300/1 comes equipped to overcome the dangers of weather, dirt, and corrosion, thanks to a tough aluminum chassis and gasketed control and connection covers. And you won’t have to worry about getting caught in the rain — this amp carries a full IPX6 rating against water intrusion, so it’ll play on through a storm. (You can spray it, but you can’t dunk it.)

Compact technology

JL Audio’s NexD™ Class D amp technology delivers power efficiently and with low distortion. You’ll get remarkable sound quality from an amp that fits into the kind of tight spots often found in marine applications. It’s also ideal for your motorcycle, ATV, golf cart, tractor, or any other vehicle using a 12-volt charging system.

Controls for the MX300/1 are on the underside protected by a sealed cover.
