This has been driving me crazy. I took the door panel out three different times to see if anything was wrong with the speaker but no. I bought ANOTHER new speaker and replaced it anyway but the same deal so it is not the speaker. Can anybody help me why this is happening and how to fix it?

By the way, you can't really hear how terrible it gets at certain moments of the song by just watching this video. You gotta hear it in person. It is literally terrible. It makes me not wanna listen anything. By the way i do not turn it all the way up. only till 24-25 and the radio maxes out at 30 i think.

here is the video, i hope it gives an idea.

ONLY PASSENGER SIDE IS THIS WAY, OTHERS ARE FINE. i HAVE KENWOOD AFTERMARKET CD PLAYER.
