Hey I was wondering if you guys could help me out. While getting my tv/radio insatlled at a locla shop they blew out the internal amp in the tv/radio and my factory amp. They are repairing the internal amp on the radio, but my concern is now my factory amp. Does anyone know how much a new factory amp is, and where do I buy one from? Has anyone had to have their factory amp repaired/replaced, or is it even repairable? I just want to find out if the shop has to buy me a new one or repair my old one, either way im going to give them hell and I just wanna have as much info as I can. I have the SGII package by the way.
