I just find it hard to have any GOOD SQ when you are past the thresh-hold of pain.........kinda weird to me------my car does 137dBs(is not loud----I know) and I have over 3000watts on tap at any point------but @ 90dBs I can really tell the differances in true SQ songs and recordings------ok----I done----no more---I'm done on this subject.
BTW---I love all the upgrades you did-----and kept a factory alt????tisk tisk
