85 GTS Conv interior lights, speakers

Where can I get the little interior lights below the backseat windows? Mine are brittle and cracked up from the seats hitting them when they come down. Will get a subwoofer, but for now, any advice on 4 inch speakers for the rear that handle bass well? Are the front speakers 4 inch as well? Thx! :grinno:
