1984 GMC single cab pickup
(4) Ascendent Audio Assassin 8's
(1)BX 1600 amp
2.5-3.6 ft^3 of airspace
I'm thinking doind 3.6ft^3 @ 35-40hz (daily street beat tuning) and if i need/want to I can add blocks inside to take up airspace if that is too much. Subs facing the seat with a 4" aero on top of the box going above the bench seat so allow for tuning changes. How does that sound? Any other suggestions or changes?
