I think it's a 6.5" and a pain in the ass.
What did you do to your NBS GMT800 Tahoe/Yukon Today?

I believe that the Bose sub is only a 6 inch or 6.5 inch sub. But the box that it comes with makes it sound like its best gger than a 6, as do most Bose subwoofers. Honestly, the easiest thing to do is get a 00-02 side panel and subwoofer box from a Tahoe/Yukon that had the 8" rear subwoofer. That was the "premium" sound system, which actually has a factory amp and subwoofer (****** though) and it was a step under the Bose equipped trucks. The Bose was supposed to be top of the line.

I've seen alot of these trucks and I've yet to see that rear grill cutout, meaning the truck having the premium sound system. Anyone wanna trade? Lol

Mine came with it. And just about every 00-02 I see in the junkyards have them. Starting in 2003, they stopped putting an 8" sub back there, because they did away with the "premium" sound system option. Either regular stereo or Bose. And the Bose didn't have an 8" sub back there, they had a tiny sub underneath the center console. But instead of making a smooth rear side panel, they made a fake grill in that same spot. What sense that makes is beyond me.
My cover was like that but it had the Bose subwoofer enclosure which has a small Acoustimass sub which isn't upgradeable and didn't provide enough bass.
The Bose sub isn't upgradeable, see my other post. It's not a very good sub either. Good idea, but it needed a bigger driver. And amp.

That's the same one I have. There's a factory amp bolted to the top of it, but I don't think it was used for the sub, doesn't look like it anyway. Looks like a 6x9 in there. So there's no way I could use it then? We were listening to the Bose in the Denali for awhile, and it sounded pretty damn good! I was surprised how good it sounded.
Yes that amp was used for the sub as well as the 8 satellite speakers. I still use mine for the satellites but went with a dedicated 450 watt monoblock for the JL 10" sub I installed. The sub in the Bose enclosure is around a 4 x 8 and it's 2 ohms, special size, can't be changed to a standard size. I mean, it sounds ok, just not real loud.

Shame I can't do anything with it. How many ohms does a sub usually have?

Most subs are 4ohms. There are 2ohm and 8ohm subs, but 4 ohm is by far the most common.

Funny this rear sub panel over the NBS years. That's why I asked the questions. Mine is an 06 LS. Of course there is no sub back there, but the speaker grille is molded in to look like it. The perforated bits are not cut out. I found the 00-02 box, just haven't moved forward with the actual sub and amp. Good info guys. Thanks. I also do have a Suburban 00-02 sub box if anybody is interested.

Lol its just because you're unfamiliar. Once you've had the intake off the first time, it's easy. Be sure to torque them proper and exact then seal the hole plugs with RTV

Yeah, I have been reading up on it for quite a while, and watched several YouTube videos as well. I even went to Harbor Freight and bought two torque wrenches, one for Ft/lbs and one for inch/lbs. I lucked out, they just so happen to be having a 3-day sidewalk sale this weekend and they were only $10 each. Normally like thirty or so each. I got the sensors, the harness, some rtv, and im slowly working at it. The thing that's taking the longest is cleaning. There's 15 years worth of crud on the bottom of my intake. Taking a break and typing on my phone with black fingers, lol.

Got tired of using my number 1 faded key fob, so broke out number 2 which looks new.

Fuuuuuck. My tube of gray RTV sealant is frikkin dried up. Can I use the blue one? I have an unopened tube of blue RTV silicone.
That's funny- I had bought one from a locksmith a couple years ago for $80 to replace the only one I had that got lost. Then a month ago I noticed it was getting hard to see the lock symbols so I ordered one online for $10 shipped and programmed it myself. I was thinking "score!" but this week I noticed both lock and unlock symbols are nonexistent. Oh well, they both still work and I know which button is which. Still can't beat a $10 key fob!
I've always used the blue. Go for it!
