My 01 ss has been having some issues after putting in a new battery (crappy walmart battery just stopped working one day and had to jump the car 3 times)
It seems like its usually when i hit a bump that the fuse for my radio blows, but when it does my gauges dont work, but will randomly turn on and off as i drive. I've checked all my wiring for my aftermarket head unit and it all seems fine. I cant figure out what could be doing it though. I've tried posting on here a few others times but no one responded. At this point im thinking i fried my BCM when i jumped it but im not completely sure. Any help would be appreciated!

 

Wire throught stock speakers? Factory amp?

 

You blow a fuse each time you go over a bump?? If that's the case, I can't see it being a BCM or PCM (and I've never heard of either of those blowing a fuse, not saying it's impossible, just I never heard of it).

My guess is you have a bad connection/damaged wire that when it moves as a result of going over a bump, it's shorting out and your fuse blows. That's my best guess.
