Re: Help needed improving stock gm sound, please...
You can put "bass blockers" inline with the speakers to keep the low bass out of them. I would start with 75Hz or 80Hz blockers (check Crutchfield) and see if that does it.
Upgrading the speakers would of course help. Adding an amp would be a good solution too, since you can set the lowest frequency the speakers wil play.
