I have my 1993 10" 8 Ohm PCH-108 Punch series subs that I'm going to put back into use ...

But, which side is positive / negative when looking at this? There's no decipherable markings I can tell. My guess is right side looking down.

Thanks!

battery test it. Take a AA battery (or similar) and attach a wire to each end. Then connect to the speaker and see which way the cone moves. If it moves out, the polarity is correct. If it moves in, its wrong so switch it.
