1091A sub internal speaker connection polarity
Youngling Posts: 2 Join Date: 7/5/15 Recent PostsUnfortunately I didn't pay attention to the speaker connection polarity when I disconnected it.
There are blue and black wires and it is not obvious to me which is the positive (blue or black).
The speaker itself has a red spot marked for the positive, but either the blue or black cable running from the PCB could be the negative.
I don't want to connect it out of phase so if anyone knows, please tell me:
Which is the positive signal cable, blue or black?
Thanks.
