Selling a set of used Kicker SSmb6, oversized 6 1/2" midbass woofers. One of the two works and the other recieves the signal and music, it just doesn't produce it. If you push down on the woofer cone a little then it works but if your not appling pressure then nothing will happen. i'm sure its probably an easy fix. Send me a PM if interested or post and ill respond ASAP.
