After reading some of the threads, are you pushing the speakers past the point of normal excursion, and you are “HEARING “the speaker “POP”out of the driver? When a speaker is pushed past its limitation, it make an odd clicking kind of noise, hard to describe.I recently got into the bass about a month ago, I picked up an Ibanez GSR200b, a Fender Rumble 25, and some new strings and everything sounds good except for when I slap on the e string or the a string. When the string is open it sounds perfectly fine but otherwise there is a sound pop that comes from my amp. I've lowered the pickups, raised the bridge, and made 100% sure that my strings are not impacting my pickups but nothing is working.
