If you want to do radio right:
I have some excellent metal horns and matched speakers and a fantastic tube type receiver and amp for trade.
I'll trade for a dog turd shaped like George Washington, if I really like that dog turd.
I'm a very easy trade
Personally I wouldn't spend a penny on a stereo when the vehicle has a 75db background noise going on.
But I do have some fantastic equipment for sale.
I think there's a picture of the speakers somewhere in my signature thread.
