Good luck. 2 10's in a proper box is gonna be tuff to fit under your rearseat. As stated by the 10+ people above me 8's can get low and loud and will hold together just as good as any 10, 12 out there assuming you know how to properly power them. 2 sa-8's with about 800 watts will get **** loud and low in the right box of course. Or you can get you some shallow mount 10's and be unhappy your choice.
