If you use a dmm and check the voltage on your power wire and it's above 12v (although it'd likely still start if it were lower 11v eh) then it's good. Make sure your ground is good, making contact metal to metal, scrap away any paint in the way You can check the remote turn on with the dmm, make sure it's got power or your amp will never turn on. Another thing to test if your amp still works, and without using the pac is, run some wire from your rem input on amp to your power wire. This would make your amp stay on 24/7 so be sure to disconnect it after testing. If the amp turns on and plays then the problem is in your pac, if it doesn't turn on, you likely fucked up the amp when you decided to see who would win, 12v lots of current short circuit vs amp case and internals lol. funny way of putting... but sucky if that happened....
