[Accord Man]

I'd stick with a pair.

The Comp Vr is a very verstatile sub, if you want that live effect, then you should go with a sealed enclosure. I dont listen to rock or anything, but I like ultra clean sound, so I went with a sealed enclosure.

for the power, like I said before, 400-500w rms each. With that much power, a class D amp is good choice, unless you'Re willing to upgrade your electrical system a little.
