Your sub amp is stable down to 1ohm so either the 2ohm or 4ohm JL will work.

However I would go with the 2ohm as it has the highest peak and your amp says it can put out 800 rms at 2 ohh and the peak for the 2ohm JL is 1000 watts

Thanks. Will double check with 1 or 2 stereo shops.

I'm by no means an expert in this subject, but I can point you in the right direction if you're in for some good reading about car audio.

www.the12volt.com is a great site for this type of thing, and probably more active than our sub-forum here.

Good luck and can't wait to see it.
