will this box work and sound good?

i have been going back and forth about where i want my sub at and i kinda came up with a place that i think i might like. can i build a box for my sub on the rear deck behind the back seats? it would only 8 inches deep though, i odnt want it to come above the back seats. will this sound like crap?

they have no boxes that i am talking about. i am talking baout building one right behind the back seat about eight inches high.

You could just find a truck box that fits back there...... It should sound alright, it will have the back glass to bounce the sound off of. Just try it and find out. If you dont like it, just sell them and try again. Just remember they are going to be in direct sunlight, and EVERYONE will see them.
