First off I'm new here.......and hope that my question is in the right place. I have stuff left over from different cars I have had in the past and u was considering putting these pc all together in my current car. I have 1- 06s12l74,1- ss components, 1- ss mids, 1- zr120, 1-zr240, 1- zr360. My current ride is an avalache so I was going to build box in bed and take midgate out. I would like to use all this stuff because it's just setting around. Any and all suggestions or recommendations welcome.
