Hey, I was wondering if someone could help me with making a simple box for my subs. They are Kenwood KFC-W3002 12 inch subs. I used to have them in my GTA TA in a custom box that came in the car, but now that I am buying a Bonnie I need to make a box for one. Online they say they are sopposed to be ported but I had them in a sealed enclosure and they did the deed, and as you can tell I never made a box before and heard sealed are a lot easier to make. Any help anyone can give me, demensions, plans whatever help you can I have all the tools I believe just need the know-how.

I dont really want a rolling vibrator or a noise maker, just want something to put out a lil more bass than stock. I will be adding a Blaupunt MP3 Player along with what I would assume is stock speakers since I believe old people had the car before the dealer. The amp Im running is an older style Kenwood, I think it can handle pushing one since my old amp got stolen out of my GTA at work. Thanks guys and this is a great site. Sorry for the novel just wanted to get all the info out

I think this is what your looking for, great site lots of info.

Box building is an art, find programs online that calculate the boxes volumes with the T/* parameters of the woofer. Sealed and ported woofers are pretty interchangable, but not as much as bandpass.

don't make any one side in a chamber 3x as long as the smallest one, don't make it square either.
