I am going to install a Pioneer Premier 740w, a 12" Polk MM, and a 2.4 farad capacitor. I'm trying to conserve space by using a truck box I already had.
I'm not sure whether rear, forward, or top firing would sound best.
If anyone has some pics of there installs, I would love to see them. Maby copy some of your ideas.
Right now my plan is to mount the box forward firing, leave the cap where it is. Then put the amp on a chunk of carpeted mdf with some non slide rubber on the bottom. This way if I need the trunk space, I can pick up the amp and set it behind the sub box.
Here's pics of what I have,
