Your roof dont wave/rattle? Windshiled, doors? Dash.......I mean that makes 0 sense to me. And if you are over 150 DBs.....then it dont flippin matter what rattles, ish is gonna rattle and unless you have a ton of mids and highs and plenty of power to give those, the bass more than likely is going to overcome most....even the rattles, that is till you step out yo ride.
My Protege5 that was walled off with 2 Kove Armagedon U2's and two Modded 1501D MTX subs doing over 2k each and was in mid 150's rattled quite a bit, doors waved litterally, lol! Car looked like it was gonna explode....had a ton of Hushmat deadener in that.
