Hello all, glad I found this forum.  Seems like a heck of a cool site.

I'm looking to upgrade my 2018 Silverado 1500's audio.  I love the truck overall but am somewhat picky about the audio.  I spend a lot of time in the truck and am really into music.  I've put an upgraded system in pretty much every vehicle I've ever owned,  and I'm pretty up with how to read specs.  What I really need now is the stock specs on my truck so I know where I'm starting at.

I have the Super Crew truck, with the Bose system and bucket seats.

I'm not having any luck finding out the size of the stock speakers and what OHM rating they have  And, I would really love to know what kinda RMS wattage the stock head unit pushes to those speakers. And if I'm not mistaken, the Bose system uses a separate amp, and I'd like to know what watt rating that has too.  I'm trying to decide whether just to try and upgrade the speakers, or to bypass the stock audio components such as the Bose amp completely.

Any info on the speakers sizes and such will be greatly appreciated.

The stock head unit don’t do anything as far as power the Bose amp is on the back wall behind the rear seat. I believe it’s almost 200watts. It’s hard to find Bose specs. They use a diff OHM I know that. I am pretty happy with Bose the only thing I did was add the Kicker sub under the rear seat.

Also the speaker size is the same as factory non Bose. But I’m not sure on what to replace them with because Bose has its own set of standards. I believe you would need to eliminate Bose all together.

That's how I'm leaning.  I really just like a higher level of components and sound quality than this stock system.

8ohm. 6x9 in the front 6.5 in the back.
Roughly 42.5watts per speaker per Bose tech department.

Yea I figured it was around there that’s not all that bad. I had the kicker DSP in my last 15 non Bose and I feel the Bose is clearer just my opinion.

Anybody have the specs for the radio itself?  If I bypass the Bose amp, I need to know what it's putting out RMS and low level too.

I replaced the stock bose 6” sub with a 10” JL Stealthbox that fits under center console. Added a JL audio 300w1v2 amp and audio control lc2i. I left the 4 door and 2 dash speakers stock bose running off 175w bose amp. 

 

IMO sound perfect! Lots of low end bass at ALL volumes. No more bass fade at big volume. 

 

Only problem now is center console rattles!

 

jl also offers a dual 10” under rear seat Stealthbox but I didn’t want to loose under rear seat storage.

In my opinion the Bose system sounds amazing! That’s why I decided to just go with adding a box with two 10s , maybe 12s lol. Yes I’m going to loose the storage under the seat but the stuff I got underneath the seats is nothing that needs to be there.

Amazing the size diff I Will admit the stick Bose sub is def weak that’s why I did the Kicker sub in the back. I looked at the JL sub but I was afraid of the console rattling.

I did the Kicker sub and still put the under seat storage bin just cut it off where the sub fits. The one sub is def good. Plus it’s all in 1 I like the staying as close to factory as possible.

    • 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.
    • 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. 
    • 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.
    • I have 2 choices. 
    • 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.
