class a

I'm getting ready to take our "vintage" class A on the road. I want a new head unit that fits a single DIN slot, but the screen can go above and possibly slightly below like double DIN size. I don't want to spend $1k on a head unit, but I want something nice, feature packed, that sounds decent...

I'm looking to buy a Soundstream Davinci 7 channel amp as well as a BLT-4. Working models would be preferred but I do have access to a tech that can bench test and repair the old-school class a amps. My dad used to be into car audio competitions before I was born and won multiple competitions...
