  1. well if you input the diameter of the port and the tuning you want along side of the dimensions of the box it will tell you if it will work or not. Example: if you put the dimensions in and put that you want a 4" port tuned to 35 Hz it will tell you if it is possible. If that configuration will not work it will say so in a dialogue box to the left of the cal

    ok. thank you for the help.

  2. First you need to figure out how big of an enclosure you are going to build. After you get the dimensions then you can figure out the port size and length that you need. You can use a subwoofer box/ tuning calculator like this to figure out what you need. http://www.bcae1.com/spboxnew2.htm

    i tried using the site you suggested but it didnt give any information as far as how big a port to use. i know how to find box volume and port length for tuning. my question was what diameter port i should use and what should i make it tuned at. id like to use 1 port for both 8's. i just dont want to get a 4 inch diameter port and have it be to big and make the subs sound like garbage.

  3. so im getting ready to do a small budget build in my accord. nothing too crazy just a pair of the new skar audio ix 8's d2 on a jbl cs300.1 amplifier with all execution audio zero gauge plus kinetik powercell and sony 4 channel with pioneer coaxils and sony receiver. i plan on making the box around 1.8 cubes after speaker displacement. i plan on putting in an aeroport. my question is what size port should i get for my pair of 8's? i read a thread on here about ports but i just dont understand everything fully. i was thinking a 4 inch port would be enough for both but im not sure. any help is appreciated. also wondering what i should tune it at as ive never used 8's before and didnt know if tuning them in the mid 30's would sound good or not. i checked the skar website but they dont list box or tuning specs.

  4. i would just get the d4 man. no sense in overdoing it on the amp. that way if later down the road you decide to upgrade to 2 8's you can always decide to run it at 1 ohm then. and its best to always build or have built a custom enclosure. will make your sub sound so much better if built properly. youll honestly probably never get the bass output you want out of a box that tiny. as far as running a dvc sub on only one vc u can do it but it will limit the amount of sound you get. plus you have to remember that if you only run one side you have to cut the speakers rms in half. so 300 would change to 150. but ive seen people run those sundown 8's on like 500 rms each with no problem. just make sure your signal is clean.

    Makes sense, I appreciate your reply. About the sub not having the output I'm after in that small of a box, I'm actually not after a whole lot. My car came with clarion mids and an 8" Rockford. I wanted more treble so I got some coax's and components (had factory tweeter so required no mounting or anything, just replaced) and it didn't give me the improvement I was after. I read about how the factory amp is mediocre so I replaced it with the Kappa-FIVE and it made an amazing difference. The sub had way more kick to it too which was a bonus, I was completely happy until it stopped sounding good, that's when I realized I blew out the surround around the sub so the box no longer had a seal. I'm in no way looking for something to break records with, I'm just after the best option I have that utilizes the factory box so I can retain my trunk space.

    That long story is basically it, I'm really just trying to get my bass back and in the process get as much SPL as I can while utilizing the factory box. This car isn't my primary vehicle, I use it for autocross and the occasional night out and building a box will just add more weight and I like that the factory box is already secure. Sorry about the long post, I just wanted to make sure you understood what I was after. I also appreciate the info on how the DVC subs work. It makes total sense once you point that stuff out, I'm going to order up the D4 version today. I am better off porting in .50 vs sealed @ .40 right? If I leave my box unmodified I'll have .4 after woofer displacement so that's an option. The factory box is plastic, it's definitely sturdy (has to be at least 1/4", maybe 3/8"), I hope that isn't a problem.

    hey man its all about what you want. i would say to go ahead and just try it sealed first before you try it with a port. a good sealed enclosure can get plenty loud and seeing how that one fits the sundown 8 on airspace id say give it a try. that way you dont cut and port it for nothing. the plastic box shouldnt be a problen as long as its thick enough but you may find that the sundown gives it a little to much of a beating wich may cause it to vibrate alot wich will lead to a loss in output and make it sound crappy in a hatchback or with the trunk open. that sundown should definately blow the rockford out the water no matter wich box you decide to go with. and no need to apologize for the long post. id rather have all the info to help than hardly any.
