I had my daytime and high beams go out, turn signals, windshielf wipers go out a while back when I left my car at the airport. Did a bunch of trouble shooting, even took the damn dealership 2 days to find the problem, a steering wheel column computer chip went bad, cost me $400 dolars for that stupid problem. I burned my dome light bulb once, and the tiny bulp in the ash tray went out. Then the day I put my car in storage my radio went out, have to double check but I think the clock went out too. What the hell, I do have an Kenwood cd player but it never gave me trouble even with 2 12s until I took those out and I went to install a 10 kenwood sub enclousure, it would get power but no signal, so I thought ok easy, make sure the rca cables are good, they were plugged in, so I tried another set of rca cables, still nothing, the sub would only kick if I plugged it straight to my ipod. Havent tried another cd player but it was working fine before.

 

My guess is something with your stereo is miswired, or it's overdrawing and you're popping fuses.

 

we have a light in our ash trays.. i guess mine was always out then.. haha

Probably wired something wrong, recheck it all one by one and see what comes up.

 

the thing is that those bulbs burn out. quite often. i think the reason that all of your problems are happening is from a simple bare wire or crossing the WRONG ONE. lol just pull out the radio and (i know this sucks) follow the wires as far as u can and see if u can find a stripped one or something, however, its always a good idea to check your fuses first good luck
also the cd player may have an individual input for subs be sure it is turned on in your settings
