So at 4ohm you're looking at 800w rms or 2ohm 1600rms. Personally 1600 is a bit much, unless you're running two subwoofers if you're running 1, you'd need a damn powerful one like a 15" Type R �� <-- I had 2 of these in my Silverado and tuned my Ported box down to 20hz.
If you're looking at 4ohm which in this situation id say is the best option.
Personally I'm a huge fan of Alpine subwoofers. But really you'll want a subwoofer than can handle 800/1000w rms at a 4ohm load. So if you want a dual voice coil you'll need a 10D2(ohm)
SWR-10D2 - Alpine 10" Dual 2-Ohm Type-R Series Subwoofer

This will do fine. But look for subwoofers that can handle 800w rms or a little more at 4ohm
Without a ported box, which I'm not sure if you have, you might not get fantastic results but it will sound decent.
In short.
You have two options
4 ohm load 800w rms on subwoofer (you can get SVC4ohm, or DVC2ohm)
2 ohm load 1600w rms on subwoofer (you can get SVC2ohm, or DVC4ohm)
SVC - single voice coil
DVC - dual voice coil
Find a subwoofer that is in those categories and you'll be fine.
If anything here isn't correct someone please jump in, I'm a novice.
It will be damn hard to find a 10" that accepts 1500w rms that doesn't break the bank.
Try the one I linked. It will go perfectly with your amp.
