What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[the_tool_man]

... Sometimes I'll crank it loud with Boston's Foreplay/Long Time track and it feels like I'm in the studio.

One of the best songs...EVER. You, sir, have lived well if you recognize that.

what are trying to accomplish? there isn't really anything to plug-n-play in place of what you have already, you can adapt things to work but you are going to need to spend some bucks to beat the bose system in sound quality, I am into mine a couple grand and haven't even touched the bose speakers or amp yet, that's all in the headunit and adapters, a pair of subs and a sub amp. changing the speakers to say a component system and a decent multi channel amp is probably another couple grand (just in parts) in order to beat the bose.
If you are going to change speakers I would recommend the infinity kappa series, but there not going to sound good without a good amp to go with them, just changing speakers doesn't accomplish anything because the ohm's are different and the bose amp has built in filters to each channel

Yeah I was disappointed to see it was the bose system because it means more work for me. I was just looking into speaker/amp replacements that would sound better for a reasonable price...sounds like that may not be a reasonable expectation tho, but I'll keep looking

I am not trying to discourage you or anyone from upgrading the system but just know it's going to take some doing and some money a LOT in order to make it better, you won't be able to cheap out on it and expect good results not gonna happen, take my word for it I have already been there done that. Adding just a sub and sub amp does wonders and it is easy to do.

Yeah I most assuredly understand the benefits of a good sub to enhance an otherwise mediocre system. I'd have to look into placement options for it and the amp. I'm sure there are many threads on it. Thus isn't like my home system where I can just buy a massive sub and corner load it to appease the wife...

The Lexicon system in my old Genesis was about as good as I've ever heard for a factory rig.

I would look into the infinity kappa series, prices will vary from model to model but they are good sounding and good quality speakers and they should last for many years and most of them are not absurdly priced for the most part.

You buyin’?

Yessir. Get it fixed, then send me the bill.

That's one great thing about living in SC. State law requires everyone carry zero-deductible glass breakage on their car insurance. It's "free", which means it's built into the premium somewhere else, lol. But at least there's no incentive to drive around with a broken windshield.

You’re paying for it lol. It ain’t free. There has never been any extra insurance coverage invented that you don’t pay extra $$ for.

 

[Rocket Man]

Agreed. And even then you'd have to have a way to tune the output of all of the components in such a way that they're optimized for the cabin. I have yet to see a sound system as well-engineered for the space as when a car manufacturer does it right, and GM did a pretty good job with the Bose system on the GMT900. The factory system in my Land Rover is an Alpine, and the one in my old 2014 BMW was a Harmon-Kardon. All three are a quantum leap ahead of any aftermarket system I've ever heard. Even the 28-year-old Bose system in my '94 Acura Legend still sounds amazing. Sometimes I'll crank it loud with Boston's Foreplay/Long Time track and it feels like I'm in the studio.

Exactly. I have the Bose Lux amp in my 02 and use it to run the satellite speakers which I have replaced with better aftermarket ones with the correct ohms, and I’m running a mono sub amp to run a 10” JL sub in a Thunderform enclosure with a Pioneer HU with wireless CarPlay. I consider it a hybrid system. The Bose has an awesome sound stage presence with surround sound effect. It just never had enough bass or control. Now it sounds great.

Ah, the 'ol port & polish

Ah, the 'ol port & polish

I went light on the polish.
Hard part with this is getting a nice crossbuff that fits in the hole, so i have these little ones that are pretty worn, fit perfectly in there.

I could have done better if i was willing to modify/ruin another tiny one with a coarser grit (green).
but I decided this is good enough.

Just really trying to reduce turbulence in the flow.

 

[Monz11]

Realized today that i apparently have the Bose system. Idk how it took over 2 years to realize...now I am looking into replacement speakers and amps...is there a website outside of Crutchfield that builds replacement kits? The offerings from there are pretty limited. Guess I'll be spending some time in the audio section

Just get the sizes, etc. and you can look on Ebay, etc. I bought an Alpine X308, and the surround to fit. I went directly to both Alpine and Panasonic sites to find out what would fit

That looks way better than I was picturing. The painted bezels and everything else black makes them look more machine-like instead of fish-eyed.

What steering wheel control adapter or interface are you using? Mine can be programmed to assign the various features to certain buttons, but the default settings for my Pioneer were perfect as-is.

Thanks! I love them. This is what I’m using. Mine is the same way, and you move those little switches on the side in the red area depending on what stereo you have. I was messing with the control settings on the Pioneer itself, and I probably just wasn’t doing something correct there. But then that setting was randomly greyed out! I gotta pull it apart again I think.

 

[Just Fishing]

Well, that was interesting.

Since i did this crap ass backwards, i decided it was easier to remove the swaybar, then roll everything forward then down.

I went on ahead and changed my grill from vertical to horizontal grille, cleaner look. then swapped out the headlight kit with a smoked headlight kit, and drop the back two more inches so now it’s pretty lowView attachment 366030View attachment 366029View attachment 366031

Dove into checking the AC system out today. I first bought a can of of this Avalanche Refrigerant. When I hooked up to the port the system was showing low at 15-20 PSI. Which was good news that it wasn't totally evacuated or contaminated. Here is a pic of the can and the gauge that domes with it. it's 18 0z.

Once about half that can was in and it hit about 35-40 PSI the compressor started to cycle on and off. I put the full can in and ran it for a bit and it continued to cycle, air out of the vents got semi cold.

I noticed the high line was a bit dirty and oily covered. There may be a seep from the high pressure port/valve or o-ring at that orofice connection. I got some wrenches and snugged up that connection.

 

[89Suburban]

According to the chart on the can and the weather stats I should be aiming for a steady 35-45 psi reading.

I ran out for another can of refrigerant. Closest place was Home Depot and they had this AC Pro can 20 oz.

 

[89Suburban]

Took a while for the can to get sucked in fully. Had the AC on full blast recirc front and rear. Ran it for about a half hour until the can was empty. Final result was steady around 27 psi, under 50* discharge at the vent. Will need one more can. Figure 38 oz put in or less, believe the system holds close to 48 from what I can find? Label on under the hood is toast. I am broke so I will have to wait until next week at 40 bucks a pop for this stuff. Still trying to pay my rear axle off. Run it like this for a week and keep an eye on the pressure readings to see if it drops. Let the system balance out. Will report back next week on the final results.

Pump yanked and disassembled.

Pump has some gouges in the surface, so it's a good thing i have a new one.
Overall, it's in great condition considering i know some hard metal passed into the cooler lines...

Ah. The Crux is the one interface that I have no experience with.

 

[Just Fishing]

Taking inventory, the best i can until the special tools arrive...

This transmission is amazing.
coming from a 700r4/4l60, this thing is so much easier.

We shall see if i fk this up too.
