i have a 94 toyota camry with stock speakers and stereo. Whenever i play a cassette or listen to the radio, it will only play out of the right side speakers. yet if i play a CD it will play out of all speakers on both sides! does anybody know whats wrong? Also, when i first got it, i took out an old cell phone holder that was wired into what im assuming was the stereo, but they might have just been power cables?
