Hi all, my buddy's RX8 needed a jump start and the person who helped him put the leads on the wrong way. Luckily there was performance problems, but the amp was blown out and who knows what else. He bought a replacement amp off ebay and we just hooked it up and still no audio. I'm going to check all of the fuses in a little bit, but if that's not the problem then what should I do next to troubleshoot the problem? Any advice would be greatly appreciated. thanks

 

Does your car power on and start now?

 

It's not related to your audio problem, but check the charging system when you get it running.
