I applied some Kilmat to the drivers side door and replaced the OEM speaker there with an aftermarket Rockford Fosgate. I added some denim insulation between the plastic door trim and the inner door metal. I didn’t have time to do the remaining doors so I added Kilmat to the rear hatch, the spare tire well, and over the rear wheel wells. I added denim insulation to the rear hatch too for good measure (between the plastic trim and the inner metal).
I’ll get the passenger door and rear doors done in the same manner (Kilmat, denim insulation, new speakers) when I have some more time. I’m looking forward to tomorrow’s commute to see what kind of difference I made.
Oh shoot I also used denim insulation but with foil backing (from HD). The front door speakers are woofers.....you changed just the front door woofer?
