Yeah, when you have a real good SQ sub, your vehicle even seems to rattle less b/c of less distortion causing less resonanace. I didn't even get a chance to deaden my trunk yet, but everyone asks me if I did. I've had an ed 15kv.2 in there before, and my trunk would rattle like crazy. Now the kv.2 was good SQ, before it blew, but no where near TC sounds products. My brother has the new tc-2000 15", and I mean it gets really really loud, but at the same time, has very little distortion. After 4 years of dealing with ED and that crap, I finally saw the light lol, and I would never go back, even if they were giving them away
