I have a 2014 Coupe EX-L with Navi. The problem I am having is a popping sound coming from the left front door speaker. Even if I turn off the factory radio the popping sound will continue. I have swapped the factory amp but no success in eliminating what I call distortion. I have physically swapped speakers from right to left and the problem persists on the left front channel. I feel it has to be an electronic issue in the audio system. I can pull the main audio fuse and the issue stops, but of course I loose power to navi and radio. Has anyone experienced this and would have some advise? I am leaning towards the radio being defective. Any suggestions with an aftermarket radio that is fully compatible with factory options?

Out of curiosity, have you tried running new speaker wire from the radio/amp to the speaker? There might be a break in the factory wire.

I have not tried that. Lacking the knowledge of the factory amp wire harness pin out and its location. I am hoping a broken wire in the factory harness would't be but it is a possibility. Thank you! I will have to check that out.
