I have a 2003 h2 that the batt died it when I was out of town in 2 ft of snow. Well I used jumper cables and after it started I found my radio wouldn't play. It's been a year now, radio works but no sound, no door noise, no on star noise. It's a after market CD player with the $100 box on the back so you can run the bose speakers and all.

So the radio and amp fuse are good, I pulled the plugs from the amp and C2 amp power is good at the plug. Now C1 the radio out I get nothing. C1 plug, B3- o.1 volts, b6 - 0.1 volts

So is it the amp or is it the radio, someone help I can't take no tunes any longer
