So. I have a 98 Lumina ltz, 3.8l (If that matters.) So, everything was working fine. The CD Player's been in there for a couple years at least now, I hooked it up myself and everything is hooked up good, I've never had a problem before. A couple of days ago I bought some subs and amp and hooked them up. They worked great. Until yesterday I went out and they didn't work. Also, afterwards, upon turning my car off, the backlight on my CD player didn't turn off. Checked all my wires, they're good. Disconnected the Amp/Subs completely, That didn't work. So I'm kind of at a loss. I checked some of the fuses that had to deal with the accessory/electrical stuff and they all looked good. So now I'm kind of lost. I've just been disconnecting the harness to my cd player every time I get out. It's getting old.
