Anyone start tearing down a 2019 to install sound system?

I used the JL Audio Fix 82 to fix the factory radio sound. It has signal sensing and turns on the amps. There is a a fuse box on passanger side dash that you can to get ign wire to rurn on amps.

In My Custom WT model had plenty of room to put the amps on the rear wall. I removed some of the foam and went in with no problems. I put all of my equipment there.

Hey thanks for the info.

My JL HD 1200 has high-level inputs. I used a LC2i in my last Sierra, but I’m thinking of skipping it this time to keep it simpler. You mentioned you had to correct the factory sound. So should I stick with the LC2i? Thanks again.

I would use the LC2i. If you dont you will loose you sub woofer level as soon as you turn up the volume. If your radio has the bose sysyem. If it non bose. just use Hi level in.

Also, it sounds like it’s not possible to mount an amp on the rear cab wall anymore? Is under the front seats the only option now? Thanks.

I believe that the issue about not being able to mount the amps to the rear wall is mostly in the double/crew cab models. The regular cab models have folding seats and less 'stuff' mounted to the rear wall. The new rear double/crew seats are actually two separate pieces for the seat bottom and the seat back, making it a little more complicated to remove and your seat back can't fold down without severe modification anymore. If you remove the factory jute (foam sound deadener) from the rear wall you can get an amp near the bottom of the rear seat back on the driver side and, if you are replacing the whole Bose amplifier as well, you can mount an amp in place of the stock Bose amplifier.

Hear is a picture from this thread (page 7) by HTX '19 Black Widow of the rear wall:

Has anyone located the factory common grounding stud in the rear cab of the crew cab (or one close to the rear wall)?

I want to put in as few holes as possible in the sheet metal and minimize the electrical resistance of using just any piece of sheet metal. I'd prefer using a factory grounding stud for the large gauge wires I'll be using for a system that will pull slightly over 350A at 13.8V. Otherwise, I have to run two more large gauge cables through the firewall and ground directly at the common point for the alternator and/or battery grounds. This is not preferred because I'm trying to minimize as much payload reduction as possible.

I took a quick look under the hood today to find a place to get the power wire through. It looks harder than the previous generation. Where are you guys getting the wire through? Any empty grommets in the firewall that I’m not seeing? Thanks.

96TL · July 13, 2019

Nevermind. GM gave us two perfect blank grommets, one on each side of the truck on the firewall.

I've got a single 10" Subthump box that I never used if anyone wants to buy it. My trucks rear window leaked and I got Chevy to buy it back. Upgraded to a 2500, which is previous body style, so this box isn't the right fit. Black carpet, single 10". Never even took it out of the box. For a T1 crew cab.

Anyone know the size of the torx bolts holding down the front seats? T50?

I did a simple install of a amp and 2 10"s. Used the groundshaker dual 10 downfire box and went with rockford for the amp and subs. Not touching the speakers yet. It sounds pretty good to me as it is now. Defenetly needed the extra thump.

To quote myself, the torx bolts are T50.

What are you guys doing with the tire jack? Doesn’t fit with my Sub Thump box.

Traditionally, get a AAA membership so that they bring the jack to you.

As far as anyone else, a locked toolbox in the bed of the truck is a viable option. Of course, this is a better option with a rolling bed cover that locks.

I have roadside assistance through Geico, but still...

I managed to fit the lug nut wrench pouch behind the sub box, and I put the jack in a small Rotcho mechanics bag and stuck it in the center armrest. Works for me.

System is rockin’.

Thanks all.

I installed a swing case on the bed of the truck. They go for about 200 bucks. I have the jack, lug nut wrench, small tool box, straps, rachet wrenches, zip ties and pliers in there. Awesome little box.

I got a question for you guys i had a audio control 6 channel with dsp intalled and all my speakers upgraded with audison speakers the shop piggybacked off of my bose my amp to retain all of my factory functions my problem is when i took my truck to the dealer today to have the blue screen fixed when i put my truck in reverse and reprogram the torque module the truck wouldnt take any updates they tried twice and said it froze up both times but worked fine on another vehicle then they started saying the amp i had installed wasnt letting the truck accept the software updates and that warranty wouldnt cover it and told me to put it all back to stock then come back does this sound accurate or is the dealership overunning with ass clowns?

Man thats a tough one. Did thye use some sort of module to get the the signal to the amps ? Something like a PAC module or did they just tap into the bose amp wires?
