WHOOO STOP RIGHT THERE! USING JUST ONE COIL IS NOT AN OPTION!!!
Now that I have your attention, wiring up only one coil will ruin the JL woofers, check the manuals it also voids your warranty (most manufacture say that). You will be over working the coil with power, it will be trying to move the whole woofer and the other coil/winding (the second coil is now dead weight) It was not designed for this. Not only is it bad but you will be chaging the woofer's specs.
Just looked up JL's site, take a lookie
http://www.jlaudio.com/tutorials/dvc/howWired.html You may just have to sereis parrallel (sp?) the woofers and leave it at 4ohm mono. Or you can run two woofers at 1.5 ohm, that amp may handle that.
