I recently bought a 1997 sebring and the previous owners before me jacked up the audio system and it is horrible. They wired the stereo wrong and it stays on even when i turn off the car. I have to turn it off with the power button on the stereo. They have the right stereo wire running to the rear and they spliced into it to power both rear speakers. The wires for both front speakers are visible. My question is am I going to have to rerun the wires and to do so am i going to have to take up the seats and carpet to do so or what is the best way to do this?
