Featured Alpine Stereo Issue. No Left Channel Sound.

[Al T]

New member here hoping for some “sound” advice….. I’m sorry, I had to.
A prior owner installed an Alpine CDE-136BT CD/Receiver and KTP-445 Head Unit Power Pack in my ‘69 Buick GS 400 convertible. The Driver’s side speakers do not have any output. I have checked the balance among other settings. Is there a way of checking signal through the speaker wiring? Any other suggestions as to why only the right channel produces sound? Is there maybe a common issue with these components?
Thanks in advance!

Generally when I have problem like that, I start swapping left for right to isolate the problem.

Like Jimi77 said, swapping wires would be a good start. Meaning, take the gray wires and swap them for the white wires. The white wires are for the driver's front speaker and the gray is for the passenger front speaker. If the passenger side ends up work but the driver's speaker still does not work, then you have other wiring and/or speaker issues.

Thanks for the replies. First step will be removing the half a roll of electricians tape.

If I ever trade mine off and leave the audio. They are gonna hate me. Everything is soldered and heat shrinked. And then wrapped in tessa tape.
