Trying to hook up multiple radios on a display board how wold i go about converting the power and be able to switch different radios and speakers?

 

If you need to ask........

 

that didnt answer my question

 

You need a large 12v power supply and a switching unit. If you don't want to lay out $3k+ for a switcher you can use Neutrik connectors and jumper cables but that looks extremely bush league...

I believe what johnw was trying to convey is, if you don't know that you need a power supply and a switcher, you really shouldn't be building a display board...

 

Right I understand all that but my problem is where to find those at

 

Your local car audio wholesale distributor will have access to all of that.

 

David Levy Co. used to sell a modular display sytem. I know they still have power supplies but don't know of they still carry a switcher.
