Help Identifying JL Sub

Digital Multi Meter. You can find one at Canadian Tire that works like a charm.
You could pop the woofer out of the box. The model number is probably on the back of the magnet...

uh quick note about the DMM, though it will give you the impedance i think the reading you get will depend on the wiring of the sub ie 2 2 ohm coils wired in parallel will give you 1 ohm, so you might think its a 1 ohm voice coil. your best bet still is to take it out of the box, but TragicMagic has more posts than me so he ranks higher than i do so if he says something else just do what he says

It really doesn't matter whether its a dual voice coil or not. What you really want to know is what the final impedance is.
For curiosities sake, if its a 12W3v3 then it will be either a single 2 ohm or single 4 ohm, therefore having the same final impedance respectively. If it is an older model then it will be a dual voice coil, final impedance of 1 or 4 ohms is a dual 2. Impedance of 2 or 8 are dual 4 ohm.

It's a dual 6ohm voice coil sub run it paralleled at 3ohm and any decent quality 4ohm mono stable A/B amp will run it just fine.......the sub will handle 500w no problem.....good score.....
