I've asked around at a couple of shops in the Orange County area, and I've been quoted $300+ installed to deaden my doors. I'd also need to take out my 8 gauge wiring currently installed, and replace it with either 2 or 0 gauge. This totals up to around $500 to do at a shop.

Can anyone offer to to it cheaper independently in the Irvine area? I can drive to your place if it would be easier.

Thanks!
