in response to ^^ there is no way you could fit that all flat across the back.
You could. The two subs on the ends and the amp in the middle. Problem is, where you going to put the speaker amp?
. The box would be too small to take advantage of the subs power, so it wouldn't sound as good.
I was still wondering if the box was ported. You guys didn't answer my question. (see above post) I wish you could make it deeper and face the subs upward. You couldn't use the spare tire, though.
