I have a 1999 Camaro V6 that I had a new radio and speakers put in about 2.5 years ago. The mistake that I made was having Circuit City (at that time about 3 months away from filing bankruptcy) install everything. A couple months after installation (and with CC long gone as a company), I noticed that my radio would restart every once in awhile. At first I thought it must be a loose connection because it seemed to happen when I would drive over large bumps. Later on, it started happening more frequently, and just at random. After awhile I started to notice that my power windows would NOT work when the radio was off. The radio would (and still does) stay off for an indefinite amount of time. What I have to do is bang on the side of the console where the radio is WHILE holding my power window button. Once the power to the radio kicks back in, the windows immediately start working.
How can this be? Should I take my car to a professional audio shop and see what they can do?
I’ve checked for loose connections and found nothing. I’m not the most knowledgeable with car electronics, but can do the basic stuff (voltage checks, etc)
