Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Who installed the after market radio? Is the radio new or used?
Open the trunk and unplug the speakers on the back deck and see if the other front speaker starts to work.
Did you try getting 1 speaker wired at a time to see if it would work?
I would wire up each speaker one at a time to verify operation.
Is the factory radio you are looking to replace a Bose radio?
When you do one at a time, it's easier to catch the mistake when you are doing it.
If it's a regular radio, that means there is no audio amp. So it should be a direct wire to each speaker. So if you wire up the after market radio one speaker at a time, starting lets say drivers front. And you don't get any sound out of it. I would hook it up to another channel on the radio to see if I get sound out of it. If I can't get sound out of it, then I would remove the door panel and inspect the speaker and check the wiring.
I would use the after market radio to test though.
Is the factory radio you picked up the original radio? or did you buy it?
Then that is why I would check each speaker and the wiring to each speaker
