Below is what I have done with my Silverado and I now have a sound system I truly enjoy listening to and it sounds awesome. 

 

2023 Silverado High Country

Bose factory system

 

Dash Speakers:

Pioneer TS-A709

 

Front Door Speakers:

JBL Club 64CSQ (Did not use tweeters)

Metra 82-3005 Speaker Mounting Brackets (free from Crutchfield)

 

Rear Door Speakers:

JBL Club 64SQ

Scosche SAGMHR-634 Speaker Mounting Brackets (free from Crutchfield)

 

Amplifier:

JBL DSP4086 (8-channel DSP configurable amplifier)

40 watts RMS x 8 at 4 ohms

60 watts RMS x 8 at 2 ohms

 

Sub-Woofer:

JBL BassPro Nano  (6" x 8" Powered Sub-woofer)

100 watts RMS

 

Harness (For tapping into Bose factory amplifier without cutting wires):

AIS - Audio Integration Solutions

([email protected])

 

Bose factory amplifier loads:

AudioControl AC-LGD 60

 

Power Harness:

Crutchfield CK8 (8-Ga power wiring kit with inline fusing)

 

I installed the JBL amplifier in the Middle compartment of the GM rear under seat storage (GM option that was on my Silverado)......I could not find a good spot on the back wall of the cab without requiring some sort of fabricated bracket and I was also concerned about the excessive heat back there. The rear seat -back has a ton of foam and will trap a lot of heat. 

I installed the JBL Nano sub under the drivers seat......it does not fit all the way due to ductwork and seat harnesses, but it fits deep enough to not cause issues with passengers feet. 

Fine tuning the JBL amp was cool and fun doing it through an application on a laptop.......I dialed it in to my taste and it sounds fantastic. 

The JBL sub adds a great bass punch to the music......it won't rattle the rust off a vehicle but that's not what I was looking for........it's perfect amount of tight bass IMHO. 

A remote bass adjustment lets you dial in the amount of bass boost. 

The OEM sub was left attached and operational.......this was recommended by many (AIS also) to not cause issues with the Bose factory amplifier having issues if it's disconnected. 

Super happy with the results......sounds sweet. 

 

Pics below.....It starts out neat and by the timeI was done it's not as organized as I'd like, but it works well and is covered with the cargo cover, so it works for me.

Yes, all except the new JBL powered sub......that is ran direct from the OEM amp sub output. 

You need to leave the OEM amp in place......it's a digital signal to the this amp.

Very Nice! What kind of music are you throwing at it? Any chance you've figured out how to unlock the Stock HU to enable scrolling on an iPod or USB or even using Apple Play now. It is all locked down on my 23 High Country once you're moving. Sitting at a stop or in park, everything works great. There is a vendor working on unlocking the system, they say the big hurdle is the 360deg camera system...

Would you mind showing your speaker inputs and outputs?  I have the same harness and Amp that you do.  Can I see more images of your wiring?  Did you use the sub input wire on the harness?

I can understand doing this upgrade from the stock sound system. The stock one in the Elevation and other variants without bose are horrific. The bose ones I found to be really good compared to some other offerings out there. What made you upgrade? I thought about doing this in my Elevation in the past, and then when I bought the Denali went with the Bose option. To me it seems pretty good. I think the only thing I'd like to add if possible would be dynamat to the doors.

Glad to hear you like yours, KinkyDuramax.  I've had two with Bose systems at this point; a '20 Denali Ultimate and a '23 Denali Ultimate.  I loved the sound system in my '20.  By comparison, my '23 system was terrible.  After upgrading the speakers I am now doing a new 12 ch amp, DSP, and stealth box sub./amp.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
