I have a Pioneer s-W110S that stopped working when a litlle conector started to wobble. i tried to fix it by soldering it to it but it didn't work yet. if i try to wiggle the connector it will sometimes give a bass tone but nothing more than a single tone. The input is audio cable and the output from the subwoofer to the aother speakers is also audio cable. So do you maybe know how i can fix it?
