So, I've decided to use my JL 12W7 subwoofer for my hometheater instead of having it in a "waking up the neighbours car". I tried using my Yorkville AP4040 amplifier, but that didn't work, since its only a 4ohm amp and the JL is a 3 ohm speaker... Anyhow, long story short, I ended up buying a Crown CE4000, my friend was running this amp for this speaker before so I know it should work. I got a cable from monoprice to convert my RCA pre out for the subwoofer to an XLR. I first noticed that there was arrows on the cable, and thinking about, the arrows are going the wrong way on the cable, so I'm thinking this cable is directional,.... nevertheless my friend told me to just try it, worst case its out of phase and I'd just have to invert it on the receiver. So tried it... and yeah, not working... So I took the cable apart, first thing I noticed was the ground wire and + wire a the opposite from the pin output from the Crown manual, this cable is reversed. From what I can tell... Looking at the cable with middle pin at the bottom, Pin 1 is on the right, and it has a black wire attached to it... I think this is the + wire. Pin 2 has a clear wire, thinking this is the - and Pin 3, on the left, is the ground shield. If my assumptions are correct, then the + wire and the ground wire are reversed... How can I tell for sure using an multimeter which wire should go on which connector? Thanks,
