Retro Sound

I'm assuming you needed a backing plate due to yours being a 68-69 vintage with roll knobs ? Or was the dash already cut ?
How is the sound BTW ?

Yes I have the original thumbwheel AM/FM radio but didn't have a face plate for it. The sound is pretty decent considering 6x9's in back and retro 2 separate 4 inch built into 4x10 bracket in dash.
