I currently have 2 10'' kicker comps and am looking for a box for under back seats. i have found this one but dont know if it will fit my kicker comps. http://www.supercrewsound.com/00F150ECdual.html any help or opinions would be great

 

Assuming you have just the basic comp sub and none of the other comp ones, it'll work but barely. It's barely deep enough so I'd opt for the increased mounting depth to give the sub room to vent. And space wise they are .7cf per sub and your subs each want 1cf so you may want to add some polyfill to the box also.
