UPDATE: Rear
So I got my rears in...They are MUCH better...but here's the deal. The rear door panels now over vibrate ALL of the audio improvements the front 4 added. They are awful! I wont lie...the rear addition actually makes it sound worse than before, in a way. I tried some at home monkey rigging to try and quiet the clapping of the rear door panels with no luck! I have yet to spend the added $50-75 on sound deadening, and really hope that helps. But if it doesn't...the factory POS rears will go back in for minimum fill...and I'll go back to praising the kicker upgrade!(front four at least)
BTW, I realize this is in no way kickers fault...its the truck rattling itself apart...
As before...factory left...kickers right.
