Based on the recommendation of RAAMmat's website, I also installed the
Ensolite IUO. Since this stuff was in one huge mat (not squares like the previous layer), it was a serious PITA to install. I should have cut it up in pieces instead of trying to install it as one, but that's a learning lesson I guess.
I did a little pounding on the metal before and after, and the difference is amazing! I'm going to also put some of this on the inside of the door panels, but I'm going to wait until I build the kick panels for the speakers to get into that.
In the 1st pic, the black lines are for my air gauges. I ran them through the ledge in the floor and then along the tranny hump and up the firewall...you see why a little later.
The black duct tape in the 2nd pic is holding down the rca cables for my amp which is mounted underneath the rear bench. I ran the rcas down the middle, the speaker wires down the driver side and the power wire down the passenger so they are all separated.
