Everything is stock on the vehicle. Stock radio running stock speakers.
The music still plays while the popping sound is going on. Also the popping is at random, and doesn't always happen... but its still pretty annoying when it starts up.
I agree that it could be something with the ground or the wires touching... so this weekend I'll have to track down the wires to make sure everything is legit.
Do I need to do anything special to remove the rear speakers? Just for a heads up if its a pain to track down the wires. Thanks.
