  2. Unlimited, and Jesters Car Audio, I know the owner personally.
  3. the last competition was in February which I attended. I know for a fact they haven't changed.
  4. yes i have the classes from the previous competition, same people are running it so classes will be the same.
  5. Because the car is a daily driver, here in Aus only vehicles allowed with a wall are utility cars like Vans Utes etc.

    well the kia pride is a smaller car so im not surprised the peak freq is higher, but I'm guessing my peak freq is in the low-mid 50's like has been stated in the thread and I was recommended 44-46 by one person and limited to 43 max by another so I figured 44hz seems reasonable since close to 10hz below peak freq seems a good place to start tuning. I had a look around other forums as well as what I was told in the thread.

    well I've got a box design coming up soon, 14 cubes after displacement at 44hz for 4 AB XFL 15"s on 2kw http://www.caraudio.com/forums/enclosure-design-construction-help/601178-plans-spl-box-optimum-tuning-frequency-trying-pass-150db-2.html#post8557784 however atm it's got 2 AB 15"s in 6.5 at cubes 32hz with 1kw, hit a 141.6 at 49hz sealed on the dash.

    Yeah I use one for competition, a 99 model, it's my friends car/system and I do all the enclosure designs for it and set up all the equipment. Btw you got any idea what the peak frequency is inside one?
  9. Yeah amps were bought a long time ago, except only 1 apsm-1500 will be connected until the battery is upgraded, then the second one is going in.
  10. No idea when, should be getting the subs in the mail this week or next, then getting a hold of wood I guess over the next few months. I'm in my last year of uni so study takes up a lot of my time but I will be trying to find time in between to make progress. Yes this box will only be used for competition, it will only be in the car on the day of competitions so it will be set up the day before. This won't be used as a daily, that's why i was fine to go nuts on the tuning since music wouldn't be an issue, I have another box for daily use.
  11. Alright sweet, this is how it looks. Plans are to have 1" thick all around with 2" on the top, and probably some bracing in the centre spot there between all 4 subwoofers because that'd be the weak spot. After bracing tuning would probably end up around 43hz, so it looks like that's the final design unless there's anything else that needs attention.
  12. here's a basic model of where I plan to put everything, cutouts for subs and port in the rear. remember I'm in australia, cars here are RHD so it is in fact on the drivers side.
  13. hmm so i was fairly close to begin with on port area and almost on volume, so would you say 14 cubes after port displacement? and I think rather than reduce the height i'll reduce the length of the box so I have more room for the box to vent. I'm also planning on having the port driver side, since the termlab goes on passenger side. edit: I'm thinking based on all the recommendations so far I'm going to go with 14 cubes after displacements tuned to 44hz, kinda fits a few musical requirements I have as well. Going on the larger side because I'll be running low power, and I did want a higher tune so 44 seems to fit. another question I have is should I mount all four subwoofers as close as possible to the rear of the vehicle? or should I place 2 near the rear and 2 near the front? remember all subs will be facing up with the port back on driver side.
  14. Alright, would you also recommend a smaller box like others in this thread have said? And how much port area should I aim for?
  15. Wow thats good, as for your questions: I'm not making a wall, the box will be built a little higher than the window line but low enough for visibility out the rear, back seats will be removed. The alternator is stock and will be stock at 65 amps, big 3 done with 2G and wire to amp is 4G and from batt to amp is about 4 metres. The battery is currently stock, but there are plans to upgrade it to an optima yellow top... however i'm not sure when it's going to happen. Thanks! edit: I really liked your ABC box, can't believe you hit 143 with a 12 on 700w, but i'm not sure which is the build thread youre referring to.
