I'm currently running two Almani S3F-12 12" 800W Vented Shallow Mount Car Audio Subwoofer at Onlinecarstereo.com and a volfenhag amp(not sure which model, gf has my car at work, it's huge with 2 meters and a fan or two) with a bad channel.

It's only running on one channel and they sound pretty good. I now have an JL JX 500/1D sitting here and i'm wondering if it's even possible to run this with two dvc 4 ohm subs. My audio guy is incognito, so I have no hands on help.
