2012 chevy Silverado under seat box

[exc500]

Just wanted to see what was my best option to go with. I want the best squeegee along with pretty decent spl. I know I have very little room to work with and I believe my debate is go with a single 10" in a ported pro box or maby the q bomb. But this is for a customer and I'm trying to get him to understand that more subs aren't all ways better especially when he wants it to fit under his rear seat.I know jl makes a nice set up but he really doesn't have the cash to do that box and a quality amp to push it. Im just looking for what would be the best set up for the money. I appreciate any input. Thanks
