psb subwoofer

[na]

does anyone have a schematic of a psb subwoofer. i'm helping a friend
with one, the audio amp ic was replaced but it still doesn't work yet.
i took a quick look at & noticed the speaker has 3 wires going to it.

any ideas why?

thanks

Motional feedback, most likely.

A bug in the hand is better than one as yet undetected.
