I have a pair of these in my Jetta, they pound soo hard, I can;t turn the amp all the way up, unless I want to replace my rear window. My rear deck has already rattled loose and I've had to screw it down. Any questions anyone has about subs, ask me...I'll help you out....
my buddy had 4 MA 12s in his grand prix, he had no back seat cause it was a wall all behind the front seats, he went to nationals for SPL and total bass decibals. Now he runs 3 15s, those MAs are a really good sub for a great price, hop on them!
