Hey guys, well I am going from one amp to another, and unfortunately, I have run into a problem. I am gong from the Bash amplifier I bought at partx express with the dimensions of 12" W x 8" H x 3-1/2" D to the O audio Bash amplifier with 10.2 Width and 11.95 Height and 3.25 inch depth. Calculating that, I'll have a blank hole in my wall of two inches in width and eight inches in height. Any way I can alleviate that? What would happen if just nailed down another peice of wood on there?
