Ford Excursion sub placement

[stiverp]

I have an ex and trying to design a box that won't take all of my storage as I am a SWAT medic and have alot of gear. I'm using 2 10" and 1 12" Memphis. Does anyone have any ideas for a box design? Thanks, Stiver

either use 1 12", or 2 10", but not both. As for placement, just do a listening test. I'm willing to bet that you'd get the most out of the sub by firing backwards, but just try every which way and pick one.
