So far I have all Pioneer stuff and I'd like to keep it that way. Just looking for a little bass now. So far I'm looking at Pioneer 12s and a Pioneer amp. Heres the amp I am going for:

And I figured I'd just bridge the amp to mono, or run one channel to each voice coil if I get a dual. Heres the subs:

Which sub would you go for? Dual or single voice coil? I was thinking of making my own box to spec. Probably just a standard box(size depends on what the sub asks for) and add one port to it. How does this sound so far? Thanks for any help.
