Whats up guys,

I randomly started to have a problem with my 05 Cavalier today. It has happened 4 times now....just randomly when I go over a really rough bump in the road all my dash gauge light reset and my radio turns off. I am assuming that it has something to do with the grounds but I am not sure. My brother and I just replaced the battery in it a couple weeks ago when I got it out from sitting for winter. I will check the battery grounds and I am going to call my local GM dealer tomorrow and see if there is any known problems but I figured I would just stop here and get some opinions on what it could be. The only mods I have done to the electrical system is disable the day time running lights. I did it the right way by cutting the wire from the harness and grounding it. I also have an aftermarket cd player with amp and subs as well. Let me know what you guys think!

Thanks!
