I was trying to troubleshoot my amp one day and my car died and wouldn’t start (It was dumb of me to work on anything electrical without unhooking the battery first). I waited a few minutes and it started right up but without radio on display on. After further investigation it turned out that neither my radio or ac plugs were working in my car. Looked online and mostly found people talking about blown fuses so I pulled each one out and made sure that none of them were blown. Not sure what to do at this point. Any suggestions?
