I bought two of these for my crew cab truck. very, very loud and moved TONS of air....for a few days! then voice coil burnout. im pushing them with a jl 1000x1 amp, less than half on the gain and within two weeks...DONE!!!! no sound or pathetic sound. i put my OLD,and i mean very OLD, mtx road thunder 12's in which are rated 250 rms and 500 peak and they sound nearly as the swr-t12 which are rated for 600rms and something like 1200-1500 peak. and the mtx's have been hitting that hard now for months and theyre almost 15 years old! If you under power them then maybe but i bought top dollar speakers that were supposed to handle being pushed....not the case. And thats why you dont but ALPINE subs.....period!
