I Need to setup a PA system in a few 30 seater coasters, and possible a few smaller buses. We currently have the stock headunits in the vehicles, which dont have any RCA outputs. I was wondering if we could just hookup an amp to these head units (which take high input), and plug in a mic of some sort, and just use that setup to run the stock speakers of the vehicle? Please give me some advice on how you think this would work, and if it would be efficient, also which amp you would suggest we get.
