I just got a 3 12 box and its 4.5 cubic feet and is vented.The chambers are shared so the subs push thru the same chamber and then out three vents.I have 2 soundstorms 300watss eachrms and 1 alpine r-type 500 watts rms.I have the 2 soundstorms hooked up to a pioneer gm-5100t 2 channel amp which gives them about 300watts each.And a audiobahn mono 800watt to the alpine rtype.Everything sucks.It sounds worse than when I had just the alpine in a single bandpass box with just the audiobahn.Heres my question.Is this box the reason why it sounds bad.I mean its a huge box and it shares its vents with all 3 subs.I want to get another amp like the audiobahn and 2 more r-types but not if its going to sound awful.What should I do.Please help,Im up to 1,200 spent on a system that sounds like crap.

Sure you can hook 3 DVC woofers to two mono amps... No problem at all.
Address ONLY one voice coil of each woofer, and hook one VC of each of the three woofers to one amp in parallel.
NOW, forget the three voice coils you just hooked up, and do the SAME THING for the other three voice coils to the other amp. Easy peasy, japanesey.
Youll be running about 1.3 ohms per channel, so keep that in mind.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

And I did connect all 6 voice coils... three total, wired in parallel, one voice coil from each woofer to each of two amplifiers.
It can be done.
