Hay everyone,

 

Just got a 19 Chevy 1500. Im looking to add a small sub-woofer. I need to find out the color coding on the wiring harness for the back left speaker.  

My amp has a high level input and I want to tap in in an easy spot. This picture is from right be the power seat adjustment control.  

 

does anyone have any subjection where I might find a wire diagram. Been looking but no luck finding it. May just be to new to have that info out in the wild....

Disclaimer: I have NOT verified this.

 

I found the following in the Electrical manual I found at GM-Uplifter

 

{Images moved to bottom so as not to bury the text}

 

Looks like GN/BK (-) and GN (+) are the two you need for the Left Rear Speaker outputs.

 

MM |   color   | Circuit | Description

0.5   | GN/BK |    116   | Left Rear Speaker Signal (-)

0.5   |     GN    |    199   | Left Rear Speaker Control (+)

 

0.5mm = 24awg

1.5mm= 15awg (approx)

 

Based on my search in that document, and the location you are seeing it at, the larger gauge (1.5mm) BU/YE wire you are looking at _might_ be circuit 277-- Driver Power Seat Recline Motor Rearward Control
BU/YE is used throughout the vehicle for many things, none I could find had anything to do with Audio.

 

My suspicion is that due to the low wattage the head unit puts out, 24awg wire is all they used for the speakers. My opinion, not fact though...

Curious if anyone has gotten the adapter for a 2020 GMC Sierra.  Where is the amp located in the Bose Premium sound package.  

 

Thanks.

I believe the amp is under the center console.

I’m pretty sure the amp is behind the rear seat.

If you have the Bose system and are only trying to get the audio signal for a sub, you could just tap into the Bose sub's speaker wires below the center console instead of a door speaker signal. You don't have to remove the center console to access it and it was't too difficult to locate in my 2020. In addition, the signal has already been through a crossover so no highs are coming through.

I just saw a post about this. Looks easy enough. I just want a sub added to my system that's it. I was told I'd have to disable the ANC? How do I go about doing that?

Thanks.

Can you give us more details on this?

Sorry for the late response JIGGZZ. I haven't been checking my notification lately.

Here's an older post where I tapped into the Bose sub wires for my low frequency signal to my aftermarket amp.

What is a 2014 Corvette Premier?

GM produced 500 Premier Edition Laguna Blue 7 Speed 3LT Coupes with a special numbered dash plaque, special wheels and Brownstone Interior and 550 Premier Edition Lime Rock Green Automatic Convertibles as well. Nothing extremely special just loaded with as many options as they offered and just first year of the C7 and you couldn't order them, GM just shipped to certain dealers of their choice and then to be sold to customers.

      Joke Thread

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
