    Box build for 2 10" IDQs

    Well I got 2 IDQ V3 10s sitting here along with some scrap wood. If I had some more wood, I would do a 4th order for them, but the sheet I have is 49x40, so Im just sticking with sealed.

    Box will be 1.8 cubes after sub displacement. Got 2 amps to try it on... Will try it on a Clarion DPX11500. Its wayyyy too much power for them. Amp is a beast. Will be very easy on the volume for a quick test, then Ill hook up my DLS Ultimate A5 to them. Havent hooked this amp up either, so should be cool seeing it in action. Does I think 600rms on the sub channel @ 2 ohms.

    Dont have anything hooked up in my doors, so I gotta get some highs playing. I have a set of Crunch GTR coaxials ($29.99 brand new FTW) that I put in the doors just to sell it. I tried bridging them on a Crunch 1800.4 and kinda got one a little toasty... But hey, I bought them to make noise, not sound great. One is a little screwey, but they still work. Got the wires hanging under the dash, so will just hook something up temp to them.

    Heres the box. Simple square. Will post pics when its done.

    Yeah, its a sealed box tuned specifically for the lows.

    Box is cut, and partialy assembled. Just taking a quick break before I go buy some more glue. Running out FTL.

    Re: Box build for 2 10" IDQs

    Yeah, Im trying to find some SQs. I know that I gotta use some DBs to find them, but in the end, I will have many SQs.

    you're doing it wrong

    for every SQ you add, it is multiplied by w7 dbs, which ultimately ends up being ~ twice as much as infinty. more or less when you factor in JL rise

    Re: Box build for 2 10" IDQs

    Whats the equation for that?

    I just want the most SQs I can afford.

    no prob, it's 1/2SQ^2 * w7 where SQ= how many SQs you want (obviously) and w7 = sideways 8

    good thing you didn't get w7s, would have been wayy more than you can afford, pal

    Re: Box build for 2 10" IDQs

    your math is wrong
    the equation for the derivative of the Sq curve is:

    db(a) + JL^2/W7^3
