Try hooking up another sub to the amp cause you may not be using the dmm correctly. It's a pretty sure fire way to figure out if it's the amp or not anyhow. Sub works fine? Not the amp. Sub works or doesn't just like the other one? Well then it's the amp.

Looks good to me... Bump that chit!

x2 When the sub quits working, push in lightly on the dust cap and see if it comes back on. . . you can also pull the sub out of the box and inspect the wires connecting the sub and see if the tinsel leads look normal. When my JL quit, i checked everything. All visible connections looked fine. I assume that my leads where broken below the spider. If this were true, and i measured the impedance of the voice coils, would that have shown me what was up by the measurements being wrong/off? And since it's a dual voice coil sub, wouldn't one lead of each voice coil have to break before it stops putting out any sound altogether?

the subs not even a month old so i don't think going out and buying a new sub would be the best way to fix the problem lol thanks though Ya, i didn't think you'd like my solution much but since my sub was over 3 years old, it worked for me. I guess why i shared my experience with you is to put to rest the, "It's the amps fault!" talk. You seem to be pretty sure it's not and i had flashbacks reading your post so... You're on the right track, good luck!

What should i get, where, and why?

I had a JL sub do the same thing to me. It worked on and off for three months or so, mostly on, until one day no matter what i did i couldn't get it to work. So i bought a new sub... Problem solved!

I have a 4 cubic foot box that i would like to install two 4" pvc ports in... How do i go about figuring it out?

Pie! Pumpkin to be exact

I drive a work van with a Sony CDX-Mp70 hu. There are no rear speakers installed in the van so i was wondering if i could bridge the rear channels with the front to get some more power up there... Any ideas?
