Well, instead of going with any 2ohm speakers I bought 4's instead and I'm going to take expert advice and run the amp at 200W x 2 @ 4-Ohms Bridged Mono into two new MB Quart QSD 216's.
I'll let the head unit take care of some low volume rear fill (maybe).
Oh man I can't wait..... time to research the 10" subs. =]
