Jl sub and amp recommendation

I do happen to have a very slightly used Elemental Designs nine 2x(used for a bout 2 months and only 500 miles on the car lol) and new e5.10 sub
175.00 for both.
This sub will blow away the JL 10w3
just need to know specs of subs that will fit
I can ship these Monday
I decided AGAIN to change everything in my own car so pulled out the amp and never used the sub
the sub is 250.00 new on ED website and the amp was like 200.00 as well
