The radio issue could be a couple of different issues. Could be 1, 2 or all 3 amps are bad, they cost $220 each to replace at Willman's Electronics. The head unit could also be your issue, Willman's will repair yours for $200, as long as its not too far gone, if it is, you can buy a used head unit on Prime for around 100-300 bucks, however there is a risk of getting a bad head unit..
