The Atlases are GOOD subs. Fits pretty much what you want if you have a good ported enclosure. They sound good too, but wont get as loud.
It really matters what kinda box you have... Mine was custom made by Mark Potts and it owns. He has some 2005 Kicker Comp 12" Vrs these things get realllly loud for the price. Not as great SQ as an Atlas by any means. My dad was taking a whirlpool(farthest room in my house in the upstairs.) and he said the subs were vibrating the water when the whirlpool turned off lol.
