whats a good size box for 2 DD 9512's for daily driving

they will be running off a D3 and the subs are dual 1

 

i had a great daily box with 3.3 cubes, 3-3inch aero ports... same woofers/amp...

although it was really only used for about a week daily driving.. then i got sick of changing all the time, so i went without daily system, only SPL.


Livin loud

 

that is something along the lines of what i was thinking 3.5 cu' per sub tuned to 33-35
