Question to the OP, why'd you opt to put one sub? Is there a disadvantage to mounting two 10" subs in such a tight spot?

I'm considering doing this mod with two Pioneer 10" shallow subs you mentioned earlier. I was gonna power it with something like this:

Would you buy that, or is there another brand I should look for?

From what I read, if I wire the subs parallel, then at 4 ohms a piece @ 250 watts RMS, then a mono amp putting out 250 watts at 2 ohms should work... Am I on the right track?
