My friend shift all sound up to the front and the popping sound is gone but my dad shift it back and forgot how to shift it back. LOL- My head unit is a Sony Tripod but all the speakers are OEM Nokia. I will change it soon and plan to install an amplifier, replace the OEM CD changer (Not working) and mp3 modulator.
I will try to shift the sound to the front. The popping sound is not very loud though. That’s why I’m still wondering the mystery of that loud “TAT TAT TAT “sound. Why it makes so loud noise like something is very lose..
