Alpine SWR-10D4 Type-R 10" Subwoofer with Dual 4-ohm Voice Coils
the product cant handle the 1000w. i have an alpine mrx m100 amp and the gain was dialed to just under 3/4 and the sub blew, it stopped working and when i took the sub out of the box smoke started pouring out and there was chunks of metal in the box and the coil was all mangled into a knot on the inside. ive gone through two of these and wont buy another one or any other alpine sub.
