To me yeah kicker is redickulous loud but not much SQ, again they aren't exactly SQ subs though neither are type Rs, I love my Type Rs they are loud as crap and pretty clear...but they are by no means an SQ sub. Mine sound good and all for what they are but if you're looking for sound quality look elsewhere the type Rs just aren't built for it, they do get loud and play the LOOOOWs though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I only put 60mil Fatmat in my car, made a big difference to me....but then again I put 100sq ft in there and caked the entire trunk/rear deck/doors in it. One piece of advice would be to really press that Fatmat in hard against the surface. Otherwise it will get loose,slip,slide on hot dayz.
