The 10W7 doesn't fit????? Not good....How large of a ring did you have to make to fit the sub? Is it noticable (any pics)? I believe there is a minimum distance that is required between the back of the sub's magnet and the enclosure. Can't seem to find it on JL's website....any thoughts? TIA!!

The shop used the wooden baffle ring from the JL packaging. I'm guessing it leaves between .25-.50 in of space behind the magnet. They painted black and it's not even noticible. I'll take a pic in a few minutes when i go outside to wash my car.

Thanks!

Pics are worth a thousand words..... still kinda sucks you had to go through that. Couple more questions for you:
1. Do you have any idea how much just the magicbox weighs?
2. Do you have to shoot holes through the battery cover to mount the box or do you remove it?
3. How tight of a fit is it -> does it move around during "spirited" driving?

I'm trying to minimize weight and I love the idea of saving trunk space but am torn between the w6v2 and the w7. The magicbox is ~ 1.25 cubic feet, which is over twice the volume rec'd by JL for the w6v2 and I haven't found anything similar to use w/ the w6 (and fiberglass is definitely not my idea of a fun DIY). Also, if I got the w6, I could just use the 500/5 and not have to worry about multiple amps (a little underpowered, I know, but it would probably work). Any thoughts?

Maybe I'm nitpicking, but if your sub doesn't fit without a .5" spacer ring, I suspect that you have less than 1" behind the pole vent. You need at least 1" behind the pole vent to get adequate cooling. Otherwise, you can overheat the coil (aka fry it) in a high power application. Then you'll be looking at a $250+ repair bill.

JL rates the power handling of their subs at exactly what they can handle. If you approach their published limit, the pole vent has to be unobstructed.

You can reduce the internal volume with some styrofoam.

WRT the pole vent, that's what I seem to remember....

As far as reducing the internal volume, I'd need to get down to about .625 cubes - that's a lot of styrofoam. Is that even possible?

As I said above, I'm looking to save trunk space, minimize weight gain and get some decent bass. I DON"T want to use an enclosure that is the wrong volume for the driver I've chosen (e.g. too big of box = boomy sound). And I defnitely don't want to fry the driver. I've heard both the w7 and w6v2; to me, the w6 just sounds better.

So, as it stands: with Dirsh's box, using the w7 I'd run into the spacer and possible overheating issue. Same box using the w6, I'd have to find a way to make the driver "see" a smaller enclosure and might still not have at least an inch behind the pole vent (event though the w6 sits an inch shallower).

Awesome.

Styrofoam will be fine even if you need to cut the volume in half. Not an issue.

In my unprofessional opinion, the heat issue would be more of a concern. Long throw, high power subs (like a W7) generate a lot of heat. In fact, thermal power handling usually determines the overall power rating. I know that the W7s suspension can handle more travel than what is advertised. A larger box will help a little. If you burn the voice coil, JL charges a lot for a recone. You can just about buy my Fi Q12 new for what they charge.

Choking off the pole vent would really limit the amount of power you can apply to the sub. Suggest going with the W6 especially if you like to turn it up.

If you want something that is similar to (IMO, a hell of a lot better than) a W7, check out an Fi Q from Fi Car Audio. Their subs are not nearly as deep so it should fit in that box will no issue. Just double check the speaker cutout.

I wouldn't think of a W7 as a good candidate for an enclosure of this type because its so deep...or even a W6V2.

Thanks for the info...looks like I've got some decisions to make.

Can you post his answers here? I'd love to know as well (prior to buying the box)....

selectproducts.com might have the correct sized ring.

any updates weather the w7 is adirect fit as advertised? it's quite misleading when the mfg states that it is made for the JL W7 and u cant install teh w7 w/out a ring.

also what about heat issues?

sorry about getting back to you so late. The sub is supposed to fit perfectly in the enclosure but it didn't. The installer made the ring for me for free. I just gave him a $20 tip because he also gave me some free wiring because my old wires were too short. I'm not too sure if my box was just a defect that was made too small. All in all im happy with the setup because it sounds great. Usually with subs I get tired of it after a while and want something better or louder. This is the first time ever that the sub sounds better and better every day.

I'd like to know how it turned out as well. I'm still satisfied with my setup. It still sounds good. It was a b*tch to take out the box any time I needed to access the battery because it was such a perfect fit. I've taken out the back cover of my tailight and now it's easier to take out the box when I need to. It's still in tight and won't come out from driving and you can't even tell the cover isn't there.

btw I just checked their site and they now carry a magic box for coupes, sedans, and verts

Add me to the 'curious of how it turned out' list. I wanted to avoid battery-cover hassle altogether, and just ended up having a box made by my shop in Salt Lake.

Just checked out wicked's site- they do have some pretty impressive stuff. Just wish someone would address the driver side!

BTW Dirsh- that W7 looks dope, my friend. Dope.

500 at www.carconceptsslc.com for my 12' JL W6.

PM sent with many pics
