i hav mtx speekers in the front of my gt..i amped them up and i heard a random popping every once in a while from the front speekers..i had my friend listen to them and he said it was the bass in the song that would cause the popping sound..sure enough i took the bass out of the speekers using the filter on the amp and i havnt heard the popping sound since..
so if u dont hav an amp..try turning the bass down on ur deck's equilizer..if the popping goes away then its the bass in the songs that is causing it.
im not sure if ur deck has it..but u can also take the bass out of the music by using a high pass filter on ur deck (if it has one)
hope this helps
