After a broken subwoofer in shipping (they took care of with no problem and without any money out of my pocket) I finally have a pair of the Mpyre subs installed. They are awesome little beasts!!! Don't get me wrong they are not as loud as the 2 twelves I had in there (not too far off though) but they sound very CRISP and clean. I was tired of having tons of space being taken up in my car and these have solved that problem, I'm in love!
