Well... I've been trying to plan a system for a while and just came across this. It seems to be a new product that I haven't seen mention of here yet.

https://brpautodesigns.com/jeep-wrangler-jlu-alpine-10-subwoofer-ring-adapter/

I know a few have made their own out of MDF or 3D printed one. Now there's an "off-the-shelf" option. I still question the integrity of the panel without some sort of reinforcement of the enclosure. The enclosure also isn't really sealed tight, I wouldn't think.

I'm still trying to decide between the MB Quart system, for ease, or peice together something better.

My JL stealthbox knocks pretty good. I too would be worried about the integrity of the stock box being able to handle more air moving.

How long has that been out? Only issue that I see is that it the sub requires 0.59 cu ft in a sealed enclosure and the factory enclosure is only 0.35 cu ft. I am about to send an email to them regarding this.

But you could use that trim ring with a 10tw1 JL audio sub. It's the one that comes with their Stealthbox and only needs 0.35 cubic feet.

I'm not sure how long it's been out, but they posted the below video on 9/15/22... so not long.


I just happened upon it while researching/planning for a system upgrade.

And the 10TW1-2 seems to be difficult to find....

I have been pushing the stock sub with a Quart 400.1 for almost three months and it sounds good. Also this is a fraction of the cost of a stealthbox. Not knocking the stealthbox, but it is pricey and if you want to keep a stock look and use the factory housing.
