    Icon32 Enough port space?

    So im fittin an 18" btl in my civic. max dimensions are 30x17x35, though i may measure how much mrore room id get if i used some space from the spare tire well. Heres what i plugged in but i really dont know how much port area i need to have and what i should tune it to so I need insight on how to change this up.


    I will face it towards the front and front fire the sub because the back seats are slanted and that gives room for the vent to breathe. I figure after someone recommends a fix on dimensions/port area ill have around 7 cubes before sub displacement. Thats 'fair' for an 18" btl, right?
    Feedback please

    The box in your picture doesn't have enough port area.

    For a 7 cube box you will want around 105 square inches of port.

    Using the max demensions your port will have to be 6" wide to get 105 square inches of port, and will have a volume of apx. 1.3ft^2 assuming it is a slot port.

    After deducting the port from your inital estimate of 7 cubes, your left with something closer to 5.5ft^2, which seems a bit small for an 18"BTL.

    Why in the hell is that box tuned to 18hz?

    1. Not even close to enough port area
    2. Tuning needs to be much higher (~32hz)
    3. Don't use the RE calc, it can be inaccurate...

    I would also suggest using an external port. That would save you a lot of box volume so you won't be suffocating that BTL.

    Also, have someone design you a box because it is quite obvious you have NO CLUE what you are doing.
