My stock drivers side door speaker goes on n off. its mainly off whenever i use the audio shit. RIght now my set up is stock .. 89 escort gt. i checked for loose connection n its hooked up right. When the speaker comes on (which is like never) the bass n voice n shit works(it works like it should) but when it dont come on, nothing comes on , but the passanger and the rears all work. What do u think could be the problem? The connection is right, the balance on the cd player is always even. Could it be blown ? if its blown why does it come on sometimes? n when it comes on, if i shut the cd player off (or radiO) the speaker stops working when i go to turn it back on.
