Q: Stereo speakers

asked by on

Only one speaker in my truck is working, the drivers side. The passenger side and rear speakers are not. What could be causing this and what can I do to fix this?

My car has 200428 miles.
My car has an automatic transmission.

Car stereos, including the one for your 1998 Chevrolet K1500, operate based on three main components. The stereo receiver or head unit, the amplifier or pre-amp and the speakers. The head unit sends an electrical signal to the pre-amp or amplifier, which magnifies the signal which is then sent on to the speakers. The speakers take an amplified signal and turn it into a mechanical energy that creates the movement in the speaker cones.

When any of these phases fails, you will likely not get quality sound (or in some cases any sound at all) from your speakers. This can be caused by a variety of issues and is difficult to pinpoint without testing speaker wires going from the stereo output to each speaker. You may also want to check your ground wires as well. I would suggest having a qualified technician, such as one from YourMechanic, to diagnose your electrical system and let you know how to best proceed.
