Automatic Noise Reduction

I recently installed the factory Kicker sub woofer to my Bose system, it is a big improvement but something is weird, I have to set the bass at -12 on the tone and the mid and treble at +7. I looked at the sound using pink noise and a real time analyzer. Those numbers got me closest to a flat response curve. I have done some checking on line and as soon as you install any kind of sub especially aftermarket the ANR starts fighting you. Amazon has a cable that you connect to the amp to shutdown ANR, just got to pull the console to find the amp and see if it will work with the 19. System. I understand what ANR does studied wave cancelation in high school physics. I know enough to know I don’t want it. Anyone adding a sub to Bose might want to check into this.

Yes the Bose ANR creates sound waves to cancel noise it picks up through mics placed  around the cab. I understand what’s happening but not sure I could explain it very well.

Are we sure the 2019s even have this feature? When I looked into it I couldn’t find it referenced in any of the brochures or specs, even for the Denali. Strange because they certainly made a big deal about it on the K2s? Dunno.

I am having the same issue in my 16’ Denali. Just added an amp & small sub and I cannot turn up the amp otherwise I continue to get a negative or weird “humming” sound. My amp is turned down all the way. The only two things I have found are to disable at least of the mics(I don’t want to cut into anything) or to use a harness that plugs into the Bose amp. Not sure which to do. Sure would like any advice.

I build harnesses for these trucks for adding subwoofers from 2007 to present and according to my schematics for the 2019's there is no ANC.Normally the microphone wires run into the Bose amp and it shows on the schematics but there is nothing for these.I thought it was strange because the Terrains and Equinox's still have it.

Shoot me an email at [email protected] can sell you a microphone bypass harness that plugs into your Bose amp which will make your problems disappear.It takes seconds to install and you don't have to cut any wires,etc just plug and go.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
