[QUOTE="JohnKuthe, post: 8527937, member: 670903"] YEP!! The "positive" and "negative" terminals are only for reference and the important thing is to have ALL your speakers wired the same. Audio electrical signals are really AC (Alternating Current) and what you're wiring for is for ALL the speaker cones to move in the same direction as all the others at every moment of the music, etc. All it takes is one reversed speaker connection to cause that speaker to produce a sound wave 180 degrees out of phase with all the others and in that case you get cancellation of the sound waves. My installer guy and I discovered the speaker PLUGS into my PDX-V9 Alpine 4x1 amp CAN be plugged into the amp in either direction which I found itd somewhat odd. but if you were using this amp you could easily reverse the polarity of your subwoofer at the amp. Label the wire once installed that it's reversed as a reminder to you and anyone else in the future that this reversing the polarity was done on purpose. John Kuthe... [/QUOTE]
