  1. I am still tinkering with numbers...but I have a question

    If I am going with design 1. (see first/original post) in regards to woofer placement, the ass end of my woofer (Alpine SWR-1541) will be facing the internal port wall. I am running into a slight issue with the mounting depth of the woofer and the internal port wall.

    My woofer is vented(?) on the ass end/magnet (pole venting?). How much room is required between the vented magnet of the woofer and the internal port wall, I have heard around 1 inch, but would like other input

    Edit: Here is the design question from my original post...

    I would like to pose the question again, which design is best, considering the length my slot port runs internally along the back wall. Ideally, I would like to go with design 3, as it would make life easier for me calculating this enclosure, save me a bit of cargo space, as well as I like this design most aesthetically. Will I experience significant losses in going with design 3 instead of design 1?

  2. unless I'm wrong, you forgot to change the port height AB18VFL. Thanks for your input, I'm trying to balance quite a bit and with this being my first ported build i want to make sure I'm taking steps in the right direction. I listen to pretty much everything. For sure a good chunk of dubstep and rap/hip hop, but i still would like some musical capability for other genres, though they get a slight bit less playing time in my Jeep

  3. I just want to clarify and learn all I can, as this is my first ported box build. You two have been speaking about port ratio, and port area per cubic foot. Is that not the number that comes out of the bar "Port area per foot" on Torres? I was under the impression that it was, and understand the need to have at least 15" per cubic foot, therefore I thought mine calculated out to 16.21 sq in. per cubic ft...Am I doing something wrong?

  4. Hey everybody.

    If you could please review my measurements and calculations in Torres' Calculator and let me know if I am on the right track. it would be much appreciated.

    ALSO...

    I have a question about woofer placement on my design. It is going to be a rear firing and rear facing slot ported box, with 3 common port walls. Where should the woofer be located on the face of the box. If you could take a look at the image below and let me know the best design taking into account my rather long port running along the back inside wall of the enclosure. Ideally, I'd like to use design #3, as I will have to play around with my measurements if I have to use either of the first two designs...

    Thanks!

  5. That is one of the first things that came to mind. I installed a Kicker 250.1 just a couple weeks ago in a friends truck and that switch was there. Was that switch a feature in the 2006 model (quite sure that is what is for sale, with the gain+frequency dials on the top plate) I can't seem to find it and am starting to assume it wasn't a feature in the 06 model

  6. Yeah it's online for $100 OBO, and when I texted him and ask he specifically said make me an offer. Would it be a good idea to unhook my bass amp and wire up the 350.4 to make sure it actually works if I go and see this guy? Thanks for helping this noob out
