Size/tuning would depend upon subs/power/music mostly played/vehicle.Right on! Hey i had a question.. regarding airspace, if you were to put 2 10's into a single chamber box compared to a similar 2 12's... what generally would be the trend for best performance? As in tuning and cu. feet
As for common vs shared, generally shared chamber will let you get away with less overall volume vs common. Meaning 2 subs that need 2.5^3 each will work ok in 4 - 4.5^3 shared chamber.
