The Rockford Fosgate R1S412
Get Rockford Fosgate bass in your car without a heavy investment. Prime Series subs use rigid polypropylene cones and butyl rubber surrounds to punch out powerful deep notes. Stamped solid-steel frames ensure long life, even under heavy fire, while the aluminum voice coil formers dissipate heat efficiently when you're pushing your system hard. And these subs look as mean as they sound.
 
The Prime R1S412 12" sub handles up to 150 watts RMS. Rockford Fosgate optimizes Prime subs for space-saving sealed enclosures, so you can expect highly accurate low end to complement your music.
