Re: ok yet ONE more what sub/amp question. (space issues)
first off I have heard plenty 10" subs that can go plenty low. More based on the install/inclouser/car they are in.
you might want to look into the soundsplinter RL-p, or prettry much any sub that can be put into a a 2-2.75^3 ft ported enclouser. then give it as much power as it can handle/you can afford. but in you case i would go 1 12" ported vs. 1 15" sealed. as for 145 at the dash, this is up to you finding what frequancys are loudest in your car and tuning the box accordingly. I would just aim for it to sound good clean and loud vs. just trying to hit a Db number.
