My 1988 Fiero 2m4 has no sound coming from the right 2 passenger speakers or the driver side rear speaker.

I noted the head unit knob that fades sound from left to right side has NO effect on speaker sound.

Basically I have 1 functioning speaker. 99% sure it is the head unit. Is this common?

I do not want anything fancy in my car. Can I install a cassette player I have? Should I go ahead and put new speakers in since mine are 25 years old?

Thanks in advance,

Justin

Yep it would be the head unit if it is factory. I would replace the speakers, as their sound is very sub par, but you dont have to. The fronts are easy to replace, the rears not so much.
You can pop off the front speaker grills and unscrew the speakers, unplug them and swap them to see if they work.

Before fully installing the cassette player, I would test those other speakers and confirm what the issue is. I had an 85 that only played out of one speaker ....it turned out that not only was the head unit bad....but one of the dash speakers was also shot

Wait , so even if you fade full right, the left speaker still works?

Speakers are easy to test. Just get a multi-meter and set it to the lowest Ohm setting. Touch the leads to the speaker terminals. The speaker should read the same or slightly less Ohms than it's impedance. For example, if it is an 8-ohm speaker, it should read 8 or slightly less Ohms. Also, you should hear some faint static from the speaker as you touch the meter leads to it. If it reads OK, but you don't hear anything, the voice coil could be "frozen".

Correct.
No matter what I do with the knobs, the sound only comes from the front left speaker.

Any suggestions for inexpensive speakers? (I already have a cassette player) I like my old school radio...after all, I am the one using the car! :P
