A pounding woofer, great all around, they can take INSANE ammounts of power for burps

none that i can think of other than u put them together yourselves and they dont make them anymore, and they hit so hard u get a headache

A very competitive subwoofer from a very reliable company, as you know Lightning Audio is owned by Rockford Fosgate, so it is instantly a hit in the car audio community. Ive been following a Car Audio SPL competitor hot and heavy with his X2 honeycomb quad coil subs, and my 10s keep up with them just fine, I own 4 X2 10's and i hit a solid 152.3 on the meter.
