Good info! Thanks I’ll look into that. 
 

yeah I have the dash speakers and doors so I think 6 total. Actually pretty clear stock I’ve heard much worse stock. 

I used LLJ customs when I did mine.  Plug and play harness and added amp, sub, and upgraded speakers.  Very loud and very clear now.  Only thing that sucks is the factory head unit on work trucks have no balance or fader controls.  Would replace it but upgraded head unit requires IOR stereo that is on-star equipped

I just looked and my W/T has balance and fader control.

UpDate on my '24 Denali HD with 12 speaker Bose.....Why I was so upset, as I had a Bose system in my '03 Tahoe, and it needed Nothing !!  Was excellent, my new '24 Bose with the Trebel EQ cranked to 100%, was like I still had a ton of Ear Wax.

Replaced the "A" pillars with Kicker Tweeters, Dash Corners with Pioneer A709 Co-Ax. Huge improvement.

Another '24 owner "sswails" used AudioFrogs in these locations with excellent results.

 

Factory option Kicker Subwoofer for under rear seat,  Beware !!  TWO versions.  Early ones had the capability of adding a Remote Bass Volume Control, with a 17ft. cable.  Chip shortage, forced a re-design, and eliminated this !!  I spoke to Tech's at Kicker confirming this.

They said the early design with Remote Bass Control will resume production "Soon".  ???

Way to tell, is the Amp if capable, has a Rectangular White multi pin Female receptacle, flush with one end, and case is square. Next to that White Recpt. will be a Female 1/8" Din port, to add the remote.

Ones Without Remote Bass, is a Rounded Corner Amp Box, and the main power & speaker connection, is on a short "Whip cable", with a Black Rect. Recpt. Plug. NO Bass Remote !!

 

I wound up doing a quick add on Kicker 46HS10 "Hide Away" 10"  180 Watt internal amp unit for $370 from Crutchfield. Will fit just about anywhere, and included the Remote Bass Control & Cable.

"sswails" on his '24 Denali / Bose, Tapped into the Right Front Door 6x9 Yellow & Yellow/Black wires, available under the passenger Rear Door Scuff/Rocker plate.

He said the Center Console 6" Sub wires ( Gn/Bk & Bl/Gy ) That signal "Rolla Off" in volume, as the main speaker level increases.

I found having the Remote Bass Control function, is critical to tailor the Sub Level, for different music. The Front Door 6x9's will loose a lot of Tone, using the Dash Bose EQ to control the Total system Bass.

"sswails" used a JL Audio Dual 10"  Sub under the rear seat.  I still need the storage for business stuff, so the "All in One"  Kicker "Hide Away" with integrated amp, worked out best in my application.

 I just installed the Kicker sub in my '24 HC 2500. I tapped the sub wires right at the front passenger seat instead of the right channel wires as Kicker suggest. I read on a Duramax forum that this was the best option as it gave "2-channel bass", but maybe it's only mono wired from the factory?? You're saying "sswails" says the signal drops to the sub as volume increases?? It made more sense to me to tap into sub power than the right speaker channel. I did buy the sub with the bass control port, but left the factory Kicker "dip switches" set as factory, Switch 1-on, Switches 2 & 3-off. These 3 switches are supposedly the signal outputs. I've also read that if you move all 3 signal dipswitches to on, this improves volume, but another guy suggests that Kickers setting is the best. EVERYONE has their own opinion. I'm going to play with mine a bit as its easy to pull the 4 screws, remove the 200 w amp and access the dipswitch rubber plug cover on the bottom of the amp. This being said, it definitely improved the factory Bose system, but I've NEVER been overly impressed with Bose anything.

I thought I'd post a pic of the factory under-seat storage that I modified to utilize the jack stowage area. Cuts easily with a 4-1/2" grinder & cutting wheel as it's just plastic with glued on fuzzy fabric. The jack stowage bracket has 2-10mm studs w/nuts that hold it in place, which holds that portion of the storage bin in place securely.

Has anybody replaced the factory subwoofer in the center console enclosure with any luck?

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
