About the MTX FPR12-04
Shallow sub, intense bass
Shallow sub, intense bass
MTX built the FPR12-04 subwoofer to give you big bass in a vehicle that that doesn't have room for traditional large subwoofers. This sub comes in at only 3-3/8" deep, so it mounts in low-profile enclosures that'll fit almost anywhere. This sub handles up to 400 watts RMS, and delivers the kind of powerful performance that you'd usually only experience with a traditional sub. A pair of these 4-ohm subs work great with your mono amp, or you can power a single sub with a 2-channel amp that's bridged to mono.
Durable design
You can push the FPR12-04 hard, and it's built to survive in the tough car environment. A lightweight aluminum dustcap protects the polypropylene cone, while the rugged rubber surround offers long-lasting durability. MTX's unique Spider Plateau Venting keeps your subwoofer running cool during intense jam sessions. This sub requires a sealed box.

Great sounding subs from small footprint, I am running two of the 12" 4ohm subs from a Rockford Power Monoblock amp in a small .84 liter box. Would recommend 400 watts for each sub. Sounds awesome in the back of the 2011 Tundra crewmax!
