well heres my situation i orderd some speaker because i thought my speakers behind my seats and the speaker in the dash(the one closest to the windshild) were blown.only the dash one on the passenger side worked. well i replaced the driver side speaker behind the seat yes i wired everything right and i turned on the radio to see if it worked but it didnt. So i just hooked up the speaker the other new speaker under the dash and turned on the radio and it worked but as i was putting in my glove box back in the frint dash speaker and the passenger seat speakers stared working but not the dash speaker that orignaly works. but when i put in my glove box all the way in the same dash speaker was the only one working. Any help or sudgetions on what the problum might be or how to fix it?

 

loose or shorted wires and when you put in theglove box it makes them not work. get a vom and start tracing circuits or just rewire the rear speakers they are easy. the middle dash speaker not so much.
