Just an FYI, I noticed that GM is selling Subs and Amps from Kicker (I think) on their Accessory site. If you want a GM "certified" install application, you might check them out.

To the guys that added a sub in their BOSE 2014 - did you have any feedback issues with the noise cancellation stuff (mics) that the BOSE has ? I'm getting a sub/amp installed tomorrow , not messing with any of the other BOSE speakers. Just want to insure I have no issues...

The rear cabin mic needs to be unplugged, otherwise you should be good.

Installed my sub last summer.. zero feedback. I wouldn't mess with the rear mic unless you have problems.

Your truck listed is a 5.3, the noise cancelation is only on the 6.2 engine optioned trucks. The noise cancellation will make the sub overcompensate and you get crazy feed back. I was unable to be sure what wire to unplug, so I pulled down the very back of the headliner and sniped the wire going to the rear mic. You may be able to get it by pulling the third brake light, its taped in the same harness.

ok.. so this is 100% verified that only the 6.2 has the active noise cancellation? Us 5.3 guys don't need to worry about it?

Yes. Look at the headliner above.the backseat, on 6.2 models there is a roughly 3" grill above the middle seat. Tjats the rear mic. There is also matxhing mic's in the middle of each entry assist fold down handle above the passenger seat.

 

To make it real simple to tap in a sub. If you pop up the door sill cover of the rear passenger side, there will be a plastic channel holding audio wires. Pull off the top plate, your sub wires will be the thicker twistested wires. They run from the amp to the sub, splice those to a loc and your set.

Seems to be a limited info about boxes and options for us double cab owners.. anyway, I had this installed yesterday. Because of the humps and curves of the floor, they had to make a custom fiberglass box. Pretty nice, fits like a glove. Also got a bass controller installed up front in the side map pocket. The bass is way more than I could ever need. The reality is I probably would have been fine with just a 8in sub after hearing this set up.

Did you have this done at Specialty Automotive Treatments in Fort Lauderdale?

Oh alright, I am looking at running the exact same setup and SAT is going to do it for me. They had told me they have done it for a few other 14s also, I thought yours might have been one, guess not lol. Looks really good though.

      AFM Experience

      By KARNUT · Posted

      The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda.

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
