Since speaker manufacturers never cease to discontinue models, if for no other reason than to generate new business by being able to say "NEW model", it is time to update the list of drop in replacement subwoofer candidates that will fit inside the GM OEM stock subwoofer enclosure designed for the 2000-2002 Suburban and Yukon XL and long wheel base Denali.
But first, let's go over the important speaker fitting dimensions of the factory subwoofer enclosure. The critical fitment dimensions for the 2000-2002 SUBURBAN and YUKON XL long wheelbase OEM subwoofer enclosure are different than the Tahoe and Yukon subwoofer enclosure. I only know the dimensions for the SUBURBAN / YUKONXL.
Internal Volume of Enclosure: Roughly 0.425 cu ft / 12 liters , NOT including the required deduction for driver displacement and the compressed volume of soft internal baffling to arrive at net box volume.
Mounting LAND Depth: From back of box directly behind centerline of magnet to the recessed mounting land that the original basket drops into: 3.125" (79.38 mm)
Mounting FACE Depth: From back of box directly behind centerline of magnet to the forwardmost external flat front face of the box, disregarding the mounting recess: 3.4375" (87.31 mm)
Mounting RING Diameter: From outer edge to outer edge of mounting recess land only. There are no holes in this land, but the speaker basket mounting lip nests neatly into it: 8.375" (212.725 mm)
Mounting TAB Diameter: From mounting tab ear outer edge extending beyond the circular recess to the diagonally opposing mounting tab ear outer edge extending beyond the circular recess, irrespective of mounting hole centers within these ear tabs: 9.250" (234.95 mm)
Mounting SCREW Distance On Center: The on center distance between each of the four original mounting screws at the recessed ear tab extensions, as defined by an imaginary equilateral square, where each corner of this square represents the center point of the original screw hole of the four original mounting tabs: 6.00" (152.4 mm)
Hole Cut Out Diameter: Original hole driver basket fits through: 7.250" (184.15 mm)
The above dimensions apply to the enclosure.
Below are just a few facts about the original driver:
Original Driver Depth: Of actual driver, not of available depth clearance: 3.125" (79.375 mm)
Original Driver Weight: Of actual driver, not including enclosure: 3.5 lbs. (1.59 kg)
It's a pretty hefty OEM driver, that says "U.S.A." on the back of it. Considering that so many of the aftermarket drivers in the small 8" size are made in China, even those offered by big name brands like JL Audio, one has to wonder if these OEM drivers are actually built better, but for the natural decay of the foam surround.
Also, you can repair this factory 8" subwoofer driver, if all that is "blown" is the foam surround. A replacement foam surround kit, with adhesive and instructions, is available online for about $18. Just search for part number EASA20PL03A1, which is printed on the back of the magnet, along with USA. That part number will lead to dozens of links on Amazon, eBay, and other sites, selling a foam surround replacement kit. The speaker is described as being manufactured by Panasonic, not Bose.
The 8" driver not being made by Bose actually makes a lot of sense, because during the some of the same model years that this 8" subwoofer enclosure was being offered, there was a different enclosure available for the Denalis and Escalades. That fancier sub enclosure was made by Bose, using their "Accoustimass" design principles.
The Accoustimas enclosure was shaped differently, but still fit within the space defined by the mounting location of the more traditional sealed 8" sub discussed above. The Bose difference was that it had two port holes instead of a speaker driver directly behind the grille area. The actual driver was tucked away deep inside the enclosure, and was much smaller than 8". The photos I've seen of it make it appear to be an oblong shaped driver, about 3" x 5" as a rough estimate. But in that unit, the driver and the ported enclosure and the amp driving them are sonically engineered for the 2000-2002 "Luxury" Y91 audio package.
Now, back to the list:
This list is geared toward the long wheel base models, simply because the box is shallower directly behind the driver opening, and as such the sub replacement options are fewer, than for the shorter wheelbase models whose OEM box is of a different design. If you have a Tahoe or Yukon, and want to contribute to this list by reporting your success at dropping in a particular model replacement sub, then please make note of that fact you have a short wheelbase in your post, because it makes a difference.
The first model Sub I'd like to start this thread off with is the popular Pioneer TS-SW841D.. It appears to be discontinued as of this writing, but still might be available at various retailers who may have remaining stock. This was a very popular replacement, in no small part due to its shallowest in the industry 2.5" mounting depth, and the 7.375" cut out diameter that is reported to drop right into place. This is dubious, according to my recent measurement of the cut out, but difference might be idiosyncratic to the basket angle.
The TS-SW841D also works with a very low internal cu ft volume in a sealed enclosure, as low as 0.15 cu ft, up to 0.50 cu ft. The GROSS estimated internal volume of the stock sub box for the Suburban is 0.42 cu in, so by the time you calculate the displacement volume of the speaker plus the compressed aggregate of any polyfill or jute pad baffling inside, a reasonable estimate of 0.32 cu ft NET internal volume is likely, which is right smack in the middle of the designed for range.
However, Pioneer has released a replacement to this model, that has higher sensitivity, lower frequency response, better matched impedence to the original sub, and higher power handling, all with almost the same shallow depth, at just 2.62". The model is the Pioneer TS-SW2002D2.
By reviewing the template in the instruction manual, it appears that outermost diameter of this new sub will not drop into the recess of the factory sub box. The factory sub box recess is 8.375". The outermost diameter of the mounting flange to the TS-SW2002D2 is stated to be 8.93", per the template print.
Well, that's it for the first installment of this list. As I learn about more replacement shallow mount 8" subs that are currently available in 2015, as opposed to long since discontinued in yesteryears , I'll add the new models to this thread, and try and figure out the models they replaced. Please feel free to do the same.
I've already made massive edits to this first post, and will continue to edit it as time permits, in order to add the additional shallow mount subs that seem like viable replacement candidates.
