The speakers can be faced either way. You get the same sound out of them. I can build a box for one 12 inch sub, thats no problem. Different audio companys like Alpine, Kicker, Boston acoustics, and Audiobahn make grills that would help protect the subs. Sorry, no more spare tire. This is a perfect box if you want a excellent sound without taking up all your trunk space. For smaller applications like one sub, I will not charge as much money. It's all about materials and time.
