MTX JackHammer JH1200 Mono subwoofer amplifier — 800 watts RMS x 1 at 2 ohms

The JackHammer Series by MTX offers just what its name implies — aggressive styling with plenty of hard-hitting power, so your system will look great and sound even better. The chrome detailing and powder-coated steel chassis with vented bumper guards provide exceptional durability, while the MTX logo lets people know you're packing serious power.

The JH1200 mono subwoofer amplifier delivers 400 watts RMS at 4 ohms. This workhorse can handle a 1-ohm load with ease, so it'll send up to 1,200 watts RMS to your multi-sub setup. Patented MTX technologies process and amplify your signal without wasting energy and creating harmful levels of heat.

Active Fan Cooling system speeds up the internal fan as you turn your volume up, so more cool air reaches the inner workings as power demands increase. Variable filters help you match the signal output to your speakers, and a bass boost lets you control the "boom" in your sound.
