So I am soon to do a big install in my 15 Sierra double cab and I plan to mount my two amps, Lc7i, and the power and ground distribution to the back wall. I don't want to zip screws through the wall and I'm in need of a method to attach either a 1/2" piece of MDF or a piece of 1/2" PVC foam board. Which should I use and how to mount it to the rear wall?
Thank you
