8s
#16
You can easily do a dual 10" or dual 12", even a single 15" setup in that much space. Sounds like this would be more less what you want(lower tuning). The "wow" effect of 8's will wear off when you realize all the low's you're lacking.
This is all personal opinion of course. If you're set on 8's, by all means blast away.
