it's dual. wire the -'s together and the +'s together, then a + and - from each set of terminals to the terminals on the amp

2 positive and 2 negative? or 4 positive and 4 negative?

each voice coil has a positive and a negative. 1 positive and 1 negative equals 1 voice coil so the 2 positives and 2 negatives equal 2 voice coils

+- +- on the left side +- +- on the right side

according to there website it's a dual 4 ohm. they also got horrible music on their website

right, so why do +- +- on both sides?

a voice coil has to have a positive and negative. wire positive from amp, to positive on one side, then from that side to the other side. same with negative

Still doesnt explain why there are 4 pairs of push terminals...

I havent seen the sub before, so I have no idea //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Edit-

I am going to take a shot at it... I just saw a pic of the sub and it looks like they might be so that you can have two sets of cables going to each coil, because its Audiobahn is has some serious power handling; hence the needed wiring //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

But it could just be for ease of wiring, I know I have trouble sometimes trying to cram two wires into a single terminal. Every site its listed on it is DVC, so I can imagine it being QVC...
