I have a down firing box built for a f150 super crew with the following specs
1 1/4" clearance under the box
Air Space = .80 cubic foot Per Sub
Mounting Depth = 5 1/4" (10" sub)
Mounting Depth based on 6" diameter magnet
I am driving it with a 500/1 and would like to know what subs are recommended. I don't want to spend more than $300/sub.
