ok i know a few people have put an aftermarket HU in their 4th gen with bose. I was wondering how to get rid of the popping sound when you change the station or song on the cd player. if anyone knows please pass it on to me. thank you

 

check your grounds.

 

Yea grounds change it, also make sure no loose comnections or exposed wires

 

ok and do you all think i should maybe add another ground closer to the HU?

 

wrong section for this question, we have an audio section for this
