I recently installed this sub in a MTX Thunderform enclosure in my Tahoe running off a Polk PAD5000 at 2ohms and it sounds great. I ran a 10W1v2 in it the Thunderform for a while and although it is a great sounding sub, I prefer the Polk over it.
Question for the OP... I see that your sub also goes out beyond the bounds of the factory sub opening in the panel. Do you get any additional vibration of that panel from reflection? Any issues with the jack access panel or did you somehow permanently afix it to the main panel? The reason I ask is the Thunderform places the sub at a similar location to yours and I am thinking of modifying the panel to place a larger opening for better acoustic transparency.

My access panels are epoxy on the inside. (yes permanent) I lined the inside of panel with dymamatt. And the box has multiple 90* brackets bolting it to the body. The main panel I occasionally get vibration from is the tailgate. Reflection is not noticeable if it's happening. I dremoled out all the vent holes and I feel that the majority of the air movement passes thru the vent. Also my box is the absolute max that can fit in the space. I used every available Inch. Any more questions fire away.

Did you ever get around to getting the dimensions taken? I am interested in building a box like this and was hoping they were available. Also, what is the max mounting depth that i can use for a sub? Th one Im looking at is 5.25", according to the math, if I did it correctly, 6" is the max. I just wanted to be sure.
Thanks, Brian

If. You ever decide to build these to sell, I'd buy one immediately to save me the time to cut the rounded area lol
How far does the box stick out from the wall of the vehicle, I'm to copy your work?
Very nice work

For Tahoes and whatnot you can buy this:
http://www.crutchfield.com/S-m8QS8MnFs1m/p_236T01B10U/MTX-ThunderForm-Unloaded-Enclosure.html?tp=129
Getting mine from my buddy who gets discounts since he sells the stuff. Can't decide if I wanna do that, or just build a custom fiberglass behind my 2nd row.
I'm sure your custom one will come out a loooot better. Good luck with it!

THat box is decent.. not as dense a sound as a MDF box but i would charge a solid 250-350 to build a hidden box for a tahoe/Burb. that pounds like mine does... thats the realty of a mass made manufacturers box.. yea it is easy to order and install but not the best design for sound or bass...
but like i tell my customers you have 3 options and you can only choose...
1. price
2. speed
3. quality
only choose 2..

box sits flush to the outer wall. flush to top of the body panel (inner supports are all cut out. the storage is cut out.. site flush to the cup holder.. then flush to the outer wall with a back taper at sub end.. so there is a 1" or so driver travel area.... the jack access and the cargor storage hatch are both 2 part epoxi closed and i spent lots of time maximizing the air space getting max air area..

Would you mind posting the dimensions of the box? What's the maximum depth?

05nali - it does not have navi i opted out bc that navi unit you cannot bypass the grounding ebrake for in motion music videos.. and i have a garmin hard wired top left a-pilar that works perfect.
finally got around to finishing up the box and final instalation tonight.. here it is.. it weighs in at about 35lbs 148 screws and a tube and a half of liquid nails.. it is a very dense box.. the amp is turned down and it rattles multiple interior pannels that will be addressed this weekend. the box is bolted to the body so it does not move.. the rear lift gate glass needed extra thick weather stripping so it would not rattle.. sounds good for a speaker still getting broken in..
the milling out of the grill is almost done,, it is very time consuming.. no room for mistakes..
I would be greatful for the dimensions and if it works great, I will paypal you $100 for the dimensions for the box and if it works good. Thank you so much and take care and I hope I here from you soon?

If its not raining and I have time this weekend ill pull the panel and take some measures
zieglerj-pdm-specialist:
Just to be clear, the dimensions you are asking for from jdpber are for a short wheelbase Tahoe, not a long wheelbase Yukon XL.
If you notice, the location of the speaker grill is much higher on the Tahoe than it is on your vehicle. Also, the Tahoe is much taller than the Yukon XL box, and is closer to the curve for the wheel housing.
jdpber, I'm not trying to take $100 out of your pocket, but based on some concurrent threads and recent posts made by zieglerj-pdm-specialist, I think he is looking for a box for a Suburban, which isn't the same as a Tahoe.

That is true so jdpber don't worry about messing with your system and taking the time to measure it out like Sub said I need measurement from a Suburban, Yukon Xl, or Yukon Xl Denali. Thank you so much for offering your assistance. Thank you for being great guys on this thread its much appreciated. ZiGGZ

Bahh, I'm in the same boat.
I'll bet there is somebody out here that wants those measurements!
---------- Post added at 01:47 PM ---------- Previous post was at 01:46 PM ----------
Hah, Yeah I know how that goes. Don't take measurements just for me though, I have a long wheel base.
It's kind of a difficult box to measure, because it is not a box. It is a generally L shaped object with multiple facets where no two sides are the same. It has to taper around the back side of the fuel inlet stamping, as well as taper in conformance with the general barrel shape of the body. Because of these gradual tapers, it is hard to report measurments that are meaningful enough to provide a box builder with adequate info to duplicate a box that is sure to fit behind the interior trim panel.
The longest measurement across the interior face width is 17.25". The tallest measurement is 9.25". The deepest measurement is 9". The shallowest measurement is 3". The narrowest measurement across the back width is 7". Yet these measurments are meaningless as they include the lips and dips, and yet cannot acount for the bows, bends, and tapers that enable the box to fit. That's probably why no one wants to take measurments... it is just too hard to account for all of the sculpting that is necessary to make a box that fits.
Hence the long standing suggestion is to either get a factory box used, or take apart your own interior trim, press some big block soft styrofoam against your panels to make a mold, and fiberglass fabricate your own box.

Fab your own is essential. As it is tight.
Not many fab their own enclosure that hides behind the Suburban/YukonXL interior quarter panel. I've seen people do it for the Tahoe/Yukon. I've seen where even MTX has made an enclosure for the Tahoe/Yukon. I've seen where one member here attempted to fab their own enclosure for inside the rear quarter panel of the Suburban/YukonXL... but he abandoned the project half way through.
I'm assuming part of the difficulty in making an enclosure with enough cu ft volume to be an improvement over stock is due to the integrated storage compartment incorporated into the interior plastic trim panel in the Suburban/YukonXL, directly above where the factory subwoofer resides. That, and the metal mounting bracket that holds the panel under said compartment, and the jacktools, and the wheel well... all conspire to reduce the available space for a subwoofer cabinet to be hidden.
And hiding is half the idea. Once the fabbed enclosure becomes externalized, the thieves peering through the window will know that if someone took that much trouble to fab that enclosure with that big 10" or 12" or 15" circle on it, then there must be a heck of a nice and expensive amp under a seat somewhere driving that puppy. SMASH goes the glass.
For those who desire stealth, and a sub box that is completely out of the way of cargo, kids, and livestock... the factory sub box from 2000-2002 is really the way to go, other than going with a JL Stealthbox under the center console... which is a monumentally larger installation project that requires cutting up internal structural portions of the center console for it to fit.
Some people don't want to commit that much carnage for the sake of a stereo. Some people are looking for drop in, plug in, and play. I'll admit I'm one of those people. The Tahoe/Yukon owner's have a choice between a premade aftermarket enclosure that hides behind the rear quarter panel (MTX Thunderform), or the GM factory subwoofer box from 2000-2002. The long wheel base Suburban/YukonXL owners only have the GM option, or make their own.
I've now only read of one person who actually completed their own enclosure on a long wheel base... and even that wasn't exactly stealth, as they relocated the original driver location, enlarged it, and deleted the cubby hole and jack.
