    Box design for 2 SA8s



    Heres a little design i came up with for 2 SA8s the box is 1.27 cubes before displacements with a 3" areo 10.75" long tuned to about 35 hertz. I plan on putting this in my 99 tacoma extended cab behind the drivers seat. Comments and suggestions are appreciated!

    If its 1.27 before then your going to be ~1.07 after sub displacement. You need to be ~1.2 after all displacement.



    Current set up: Island bombed out 92 mazda 626. Stock rust bucket

    66 Pontiac GTO, modified stock radio, Crossfire CFA 302, Kicker KS6.2's in the front kicks, Crossfire CFA 452 for the 6x9's I need.

    That's 1.27 gross before speaker and port displacements I think It comes out to roughly 1.02 after displacements if all my math is correct. It gives it about .5 cubes per sub which is what's recommended.

    Thats probably only after sub displacement port will take up even more... You need 1.2 after at least

    Recommended .6-.7 per Jacob. I JUST finished my build and was dealing with spacing issues. I'm at ~1.18 after all. Subs are .1 each.

    Re: Box design for 2 SA8s

    After sub and port displacement you're looking at 1ft^3 with a 39hz tuning...say bye bye to any low-end you were hoping to have.

    Re: Box design for 2 SA8s

    Ok I went back to the drawing board and came up with a new design that gives me 1.43998ft^3 before any displacements. I figured the port displacement to be around .03ft^3. The port is still a 3" aero at 11.75" in length and it is flared on each end. Since the subs are .1ft^3 per sub this should come out a little closer to the 1.2ft^3 at 35Hz that I was shooting for. The tricky part in trying to calculate the port displacement was trying to compensate for the inner flare of the port but I suppose that a few thousands of an inch isn't really going to affect the tuning to any noticeable degree? Again any comments or suggestions are greatly appreciated, you guys have been EXTREMELY helpful thus far!
