What type of box would make the 2 JL 10" W3 that i have sound the best? Ported/sealed? What should i make or get made for these? Looking for SQ and they will be going in a Isuzu I-280(same make as chevy colorado) ext. cab. Let me know if ideas yall have.

w3's in a sealed box should sound nice no need really for someone to build you a sealed box though...

Depending on the area you have to work with you can do them sealed or ported. Which ever works for the situation.

You can pick up sealed enclosures fairly cheap, you just need to ensure they are the correct volume. Many times they say they are xxFT^3 but are really yyFT^3. Also you would need to seal up the enclosure if you were to purchase a prefab sealed enclosure. They are notorious for leaks.

yeh i could handle building a sealed box, what size would you suggest? i built a box or 2 before but i never came up with the dimensions on my own but if i'm given them i can build it.

yeh i would seal it, how do i tell if it's xx^3 compared to yy^3???

For a sealed box if you are given the outer dimensions of 14" x 14" x 9", you can calculate the net volume by subtracting 1.5" from each dimension (MDF is 3/4" and two sides equals 1.5"). So 12.5 x 12.5 x 7.5 = 1170. Divide that by 1728 (amount of square inches in a cubic foot) and you are left with 0.68 cubic feet. If the manufacturer is advertising 0.9 cubic feet then you know you are being misinformed.

LxWxH/1728=cu ft

This is exactly right.

However, you also need to take into account your subs displacement to ensure you are at the correct volume.

ok so on JL's site, it says the ideal sealed box is a .625 cubic feet box (measurements given are 18in. x 11in. x 9in) do i just multiple everything by 2 in order to get a box to house both subs or how do i go about that?

the driver displacement for a w3 is .049ft^3

any help on how to get the dimension of a box to hold 2 10's when im given the dimension's from JL for one 10?

Just build a sealed enclosure for 1.38ft3 gross volume and you will be fine. Make the dimensions fit your application.

Do I use a divided or do I keep it all one chamber?

You can do it which ever way you want to it won't alter enough to make a difference.

I think if I can find a prefab made close to the specs i will go with it. I don't trust myself with this box building stuff haha

LOL, building is not that bad for a sealed enclosure. When ever you see some prefabs that you think may work just post up and we can let you know if they will work and such.

If you don't find anything I can do a design with cut sheets for you to help making the building process a bit easier.(It does cost a little, but is a cheaper method then having one custom built)

You're saying something like I pay you for a design/plan for a box and make it myself?

If you would like to go that way that is an option. There are a few others on here that do designs as well. We all design the enclosure to work best for your application. If you get a design from me then decide you would rather have me build it, I deduct your design price from the enclosure price.
