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.

I have a 2018 Silverado LTZ that came with bucket seats, so Bose 6+1 system with amp in back. I replaced all the factory speakers (doors and dash) and left the factory center console sub. Replacement

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

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.

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.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
