Hey guys. I have a 05 lifted ram 1500. I had a stock stereo in it and when ever I would turn up the volume the dome lights start going crazy, the light on the dash flashes saying my doors ajar and the door dinger goes off. I installed a new stereo and the guys at the shop had no idea what was wrong. It is still doing it. Sometimes it's just the dome lights and other times it's the dinger. any advice would be greatly appreciated.
Thanks

Did it do it before the lift?

 

I bought it already lifted, it started doing it about a month after I bought it. (Bought it in feb)

 

How old is the battery? Any aftermarket accessories? Check grounds, maybe they left one off. Or forgot it.
