is it the wiring?

[DSR]

I have a 91 MR2 and I just installed to 6.5 kickers in the doors and the passenger side isnt working. I tested the driver side before I put the door cover back on, but not the passenger side (should have). Anything that could cause this except for loose connection?

Before I installed these, the radio would work fine but the cd player would only play on the left side of the car (stock system, radio/cassette and cd player are seperate). I thought it would just be the connection through the wiring going from the cd to the cassette/radio but same symptoms now for both so I am second guessing what is wrong.

Any suggestions? Thank you

how do you have a different cd player from your radio? This is dumb, but did you check your balance controls? haha if not, you stumped me too...

[DSR]

Yes ha I did check the balance and setting and all that.

The system is orginal... Its all together in the center panel but the cd player and the radio/casette aren't one item, just connected with a wire. Only one volume control and settings like that....

and they all work except for the left side speakers!

So I got the left speaker to work with the radio like it did with the old speakers but still nothing with the cd. Can the wire from the cd to the radio go bad only with the strands that work the left side? Is that possible?? I wish I could play a cd in my car...

Thank you

Yes, a wire in the wiring harness from cd player to head unit can go bad. And there are seperate wires for left and right side because the signals must be kept seperate for stereo playback. The cd player transmits in analog not digital. Pull out the cd player and if the harness is completely removable then buy a new one, if not take it in some place to be repaired. If radio plays on both sides of your car then it cannot be a loose connection from the head unit to the speaker because the amplifier is contained in the radio and all signals go through that before going to the speakers.

It is seperate from the radio yeah... and both casette and radio work fine.

That is what I was trying to avoid. Hoping I could replace just the wirig from the cd to radio butI guess not.

thanks

The left audio output section of the CD player is dead. It's probably cheaper just to buy a new indash, if you don't mind losing the cassette.

If he replaced head units and the left side is still not working it's most likely a wiring problem and not a bad head unit channel. I would get new speaker wire since it's cheap and just rewire that side back up. This should fix any possible shorts and give you some fresh wire.

Did he say he replaced the OEM radio? What he has IS the OEM radio, double DIN, AM/FM/Cassette in one DIN, and the accompanying CD player in another DIN. BTW, it's NOT a bad headunit amplifier section, it's the output from the CD player's IC that's bad. Please read more carefully next time before eliminating the possible causes.

You got it Luc

Good looking out
