Ok guys, here's the deal: I have a del Sol and i recently purchased a custom enclosure that holds 2 10" subs behind my seats. It has approximately 1.2 cu feet of airspace for each sub. I know of many good sub manufacturers (I.E. Rockford, Eclipse, Infinity, etc.). But what i actually want is a 10" sub that performs well with my airspace. Any info would be greatly appreciated.
