i have mmats 12" juggernaut and i noticed it sounded like crap. i pulled the sub and found a wire coming off of the negative terminal leading into the sub itself was no longer connected to the terminal. if i place the wire into the clip, it sounds ok again. i tried to solder it and the solder simply balls up and rolls off. i am not sure what this loose wire part is called, but i am wondering if it can be fixed? soon as i get my dig cam back, i will take a pic and post, but for now, does anyone have a clue what i am talking about? thanks.
