  1. The way I have understood tunnels is the tunnel itself is the port. That is where you tune it. I'm not totally sure on that though and hopefully somebody with more knowledge on tunnels will chime in as I want to learn all there is about tunnels. Here is some info I got from somewhere else.

    For a ported tunnel

    This one is after I asked about the tunnel BILTD did in his Astro. The one that's posted here. One awesome setup.

    Hope that helps.

    Thanks man! Helped a hell of a lot! Might end up redesigning as a ported tunnel

  2. I'm looking to build a tunnel enclosure for 12 10" woofers, either DD 1510's or Sundown SA-10's haven't made up my mind yet. Each sub will have roughly 1 cube of air space. The question i have is, how do i make sure this hits the lows like i want... I've never worked with any sealed enclosures and didn't know if there was some way to "tune" it. Oh, and i will be running 3 SAZ-2000D's at 1 ohm(4 woofers per amp). I'm lookin' to have some major :hairtrick:

    heres a sketchup of the enclosure

  3. yea, it would be

    all paralleled is .67ohm to each amp...i guess a sundown could handle that after box rise so long as your electrical is good.

    series 3 and parallel, you get 6ohm, parallel 3 and series is 2.67ohm (if you wanted to strap or use amps that like 2ohm)

    or run 4 small amps at 1.33 or 1 big amp at 1.33

    get to it ;)

    Thanks dude, what would you recommend? as far as how many amps? i like the 1 big amp idea...

  4. Ok, so i liked the big square port idea and made this up...im not sure if the sub will be able to properly build pressure throughout the box with its placement in relation to the port...thoughts?

    i screwed up drawing the port a little bit, but you get the idea...i will probably use some dowel bracing on the bottom and sides of the port

    heres the tuning on it
