    why dont you make one box 3.56ft3 (1.78 x2) with the port in the middle 2 inchs wide by 17 inchs tall ( the internal length of the box ) x 7.7 tunned @ 35 hertz

    would the port still be 12"deep and i might be amping the subs seperatly in the end so i figured dual chambers might work better but i like the simplicity of a single chamber with 1 port

    Re: 2 15" davinci's in my golf

    ok this is what you do. Find the displacement of the sub. This is how much air space the sub takes up. Add that to 1.5, and you should see how big to build your box. If you dont want to do that, somewhere around 2 cubes before port and sub displacemt should be ok. To find out what a 4 inch port comes to in sq inches, you do Pi*Radius Squared which is about 12.5 sq inches. You can build the square port that is 12.5 sq inches to be the same as a 4 inch opening. Personally i would do a bigger port, something around 30 sq inches to make it sound better.

    And if you are using 1 amp, use a single chamber, and just make two ports. a single chamber makes it easier to ensure the subs have the exact same air space

    so youd go a 2 cube box with a 30 sq inch port

    do the same chamber and single slot port its tunned the same as the round port you wanted to use and you can use one amp

    ok do this 4 cube box. 1 port 15x3 opening, 26 inches long. That should sound good.
