jl w7's, which box should i go with?

hey man as far as the trunk rattle goes ill tell you a nice trade secret. loosen the latch which just looks like a loop of metal and move it just a tiny bit farther away from the clamp that holds the trunk shut. this will make it so that the truck is held together a lot tighter and might take a bit of adjusting until you find a good balance of tight trunk lid and how easy it is to close, if you move it too far then you will have to slam the trunk to make it latch. this little trick should take at least half of the trunk rattle away and it wont cost you a dime. also when it comes to rattles people dont realize that a lot of what you hear is on the outside of the car. if you really want to get rid of all rattles then you need to listen carefully to what is making the noise and figure out how to stop it. usually the best idea is to find things that are rattling against each other like tail pipes and their mounts or other pieces of metal that are close together, find a way to get something in between and the rattle is done. spray foam and rubberized undercoating are my favorites.

According to their website, that enclosure is 2.25 cuft gross per woofer and the vent is tuned to 38Hz, so it should work pretty well with W7's. I suggest you might need to add some bracing and seal up the seams depending on how it's built, but size-wise it looks OK to me. ATREND websiteSupport the12volt.com

Yea but isn't the interior volume per chamber is slightly larger then what is I tended so will it sound better if I get it closer to specs meaning somehow lessen the space inside each chamberMECP Certified

Dont Ground Out!!!

W7's actually like big boxes. i used to have an 8W7 and i had it in a 1 cubic foot ported box which is huge for an 8 and it sounded awesome. the manufactures specs are a good start but depending on the type of install and what you want to get out of the subs these specs can be adjusted to fit the listener.

Should be no need. If you are concerned that the enclosure is not dead enough, get a can of truck bed liner (like Rhino Liner) and spray it inside the enclosure to cover the walls. Let it dry overnight before you mount your woofers.Support the12volt.com

Poly fill isnt necessary if you have the space to build a nice box.
