First off let me say thanks SSA for the customer service support. the best customer service ive had online ever. Second this subwoofer Is a BEAST. I haven't hooked it up yet but my buddy has this same one and pushes easily 1200 rms without any problems. doesn't overheat and handles extremely well. just make sure you get a 1 or 0 gauge wire otherwise it will cut out. but other than that this thing slams better than the JL W7.
