ok so the sound deadener is in upto the front seats, the re audio 8s are in the doors and clear the door panels and the window. the seats are lifted 3.75 inches, the biggest task is fiding room for two sundown and a third before the build is complete. heres what i came up with. the silvy crew cab back seats have a hook on the back of the seat that hooks the back cab wall so access is zero behind there. thats is untill i raised the seats. by raising the seats it allowed me clear the hooks when the seat bottom is up. i didnt want to screw through the back of my cb or flue anything to it either so i took the seats apart and inside there is two steel bars the brace the seat back. i cut 3/4 mdf to fit inside and drilled and tapped the mdf to the steel supports. i streched the fabric over the mdf and had a soild mount for the amps. i had to do both sides. check it out.had to eliminate the middle seatbelt
