2 BOSS P156DVC 15 Inches 5000W Car Subwoofers Subs, Dual 15 Inches Sub Box Enclosure
Great subs, great box, and a bomb deal.  Box is huge for a big cadillac or suv.  I've only got one set two could be unbearable.  I had to take the box apart and then rebuild it in the trunk of my intrepid.  Fits now and even without the amp, boom.
