new guy Posted October 5, 2011 Report Share Posted October 5, 2011 It happens to me when the amp is on before the h/u is on.

spldreams Posted October 5, 2011 Report Share Posted October 5, 2011 you said all the grounds are fine? did you check the ground behind the head unit? popping issues are caused by a bad ground like 90 percent of the time Link to comment Share on other sites More sharing options...
02z71 Posted October 7, 2011 Report Share Posted October 7, 2011 i had the same problem and after a few frustrating hours, i narrowed the problem down to my cd player. pioneer head units are known for this problem because of some sort of internal fuse that messes up quite a bit and when it does it affects the signal going to the rca outputs. i was ready to send the head unit back to the company since it was still under warranty but i decided to ground the rca outputs to a small screw on the back of the cd player. its not pretty but it solved my problem Link to comment Share on other sites More sharing options...
