I have stripped everything out of my truck and want to redo everything in the interior. I took out the carpet and I want to put the dynamat or fatmat but i wanted to ask can i put the carpet over that or do i have to put watever the factory had under the carpet over the insulation mat then put the carpet or will the insulation mat be enough without the factory sound deadener over the stuff i put. Also some moron cut out the metal surrounding the radio to fit an after market radio and carved out 5 1/4 holes in the doors to put some speakers. i want it to look original. Where can i go to get that fabricated in houston, tx. Or what would i have to look for here to go get it done.
