JBL Xtreme Speaker Fix (Must Watch Please)

i bought a new battery off ebay and followed videos on youtube of how to install in the jbl xtreme and all went well, except after that the left speaker started rattling , so i tried tightening the crimps on the wires , tried reglueing the wires where they connect cone to crimp terminal , nothing seemed to fix it and that was all that was recommended as solutions by people on youtube with the speaker. but this video will show a possible fix solution for people with my problem,
