Our take on the MTX F150C04BK12-TN ThunderForm
Designed to fit
You love your Ford F-150 and you want to add some more bass to it. The problem is that you'd like to keep some room for your stuff, so you don't want a bulky box. MTX designed this ThunderForm enclosure to fit perfectly under the driver's side rear seat, so its stealthy profile conserves space while still delivering the bass you want. You'll have plenty of room for the things you need to haul, and the fiberglass construction also gives you some toughness just in case your stuff starts rolling around. You can keep your jack in the factory location, and you can still fold your rear seats up and down.
Designed to thump
MTX's custom enclosure installs under the rear seat on the driver's side, housing an efficient 4-ohm 12" Terminator subwoofer that handles up to 200 watts RMS. Combine it with an appropriate amp, and you'll get a solid low-end thump to your music, whether you're sticking with the factory audio or upgrading your system to aftermarket gear. This ThunderForm's sealed enclosure delivers tight, accurate bass response that complements a wide variety of music.
