The cab of my truck is too small to fit my twin Alpine 12" Type S's. In fact its too small to fit one of them. I was thinking about cutting the back of my cab out and welding a steel work box to the cab and bed. Another idea is putting the workbox in the bed and cutting tubes from the bed to my cab for the subs to point into. Any input would be helpful.
Also could i use a steel sealed workbox as a box for my subs, assuming it had enough cubic feet. Or would i have to make an MDF box inside?
