Something is wired very wrong. Your going to have to get detailed wiring schematics for your exact year/make/model and start learning a lot about your cars wiring !

I'd rip out anything aftermarket and bring it back to factory stock. If there are any problems in the stock wiring you might find them while taking the aftermarket stuff out. Aftermarket interior Lighting, Audio equipment, Fog Lights, Alarms, or any other aftermarket add-ons should get looked at first....... start with the last thing that was added.
