I have two 15" speakers and the box i have them in now is too large to fint in the trunk of my 04 monte. Can someone plz give me the specs on a box that will fit so i can go to homw depot and get it cut. thx The speakers are two Rockford fosgate P1 and i would like the box to be ported. thanks again

 

Minimum Ported Box Volume 2.66 cubic feet, for the P1S815, whitch is the driver i found based on your descritpion, a p1 15" RF subwoofer, anyways my friend i found this in 10 seconds do the leg work your self. if you need help figuiring out how to make it, that we'd help but your just asking us to do work for you, and that min ported volume is PER woofer. so do the math my friend.

 

wouldnt have taken less time to tell me the dimensions then go on your little rant?

 

took me 20 seconds for the rant, 10 for the specs. copy paste my friend, copy paste. good luck with your build. hope to see your build log up on the forums some time.

 

LOL made my night hahaha

 

I would love to post it, as soon as i get some measurements. I have been looking but still cant find what i need.

 

normily...nobody would ever give you the work, but im in a nice moode. so here you are.

you're looking at something thats like 30 wide, 20 deep, 16 tall. that would give you 5.55 Cf, so you'll need to make it a bit smaller than that. 2.66 x2 = 5.32, so with a port that 30x20x16 box would give you just about you want, depending on the subs the hole size is deterimned, i can't do that, as it requires a program, and the exact data. you can try and build some boxes and see what you feel sounds best. usialy something from 22-38 hz, my box is down to 32hz, but mine are completly dif woofers, with much different style cones and responses. plus i'm pusshing well over 1000 watts rms.

 

Try this!
http://www.bcae1.com/spboxnew2.htm That should help you out. It's hard to help you with exact measurements when we don't know what material or thickness you're using or planning on. Good luck with your build! Should be something of a loud car when you're done.

 

its AxBxC = x\1728 your 3 lengths being A B and C, but that only gives you the square inches, you device it by 1728 to get square feet, or you can device each number by 12 before you multiply them. same result, but remember to take out the thickness of your walls, thats a square inch or inch and a half all the way around. can really throw your numbers off

 

thank u. that helps. Ill keep you guys posted on the build
