Anyone start tearing down a 2019 to install sound system?

Recommended Posts

What version is on your infotainment system? When mine was at V805 i didn't have any issues with my aftermarket system. As soon as it updated to V807, my focal amp died. Just curious if this is more of a GM problem then with my aftermarket equipment.

I'm not sure of my version, will need to check.  I have a 2020 AT4.  NavTV people said they haven't had a chance to update everything, said it was the NAVTV unit though rather than the GM software.  They recommended my installer put in the rocker switch for a reset and that is a work around.  Before that was installed there was no sound and no fix without going back to the installer.

I'm getting my JL VX amp installed tomorrow, so hopefully no more issues for me.

If you can get the installer to provide pics of everything, that would be great.  What did you decide on the Fix82?  I'm very interested since I'm hoping to do something similar to my '19 Sierra Denali w/factory Bose.

Glad to see people using and abusing all the info here. Unfortunately, audio is one of those topics that information should be taken with a grain of salt. What I have learned is that everyone's taste is subjective, their knowledge varies, experience affects opinion, expectations are different, and not everyone is as open minded as they appear. Always 'trust but verify' an opinion that is given to you and then make your own judgement call. There are many people (especially audio forums) that will given you a recommendation which may be solely based on something they read somewhere on the internet. While it may turn out to be true, you need to be sure of that before you commit.


For those of you that are new to this, try not to be overwhelmed by the little stuff. Car audio guys can be super OCD regarding wires, installation, and imaging. That's fine, to each their own, but it throws so many of the invested folks off because you start this project thinking you'd only spend X and should get it installed pretty quick. Next think you know you're trying to figure out what wires are going to have the least amount of interference or which screw is the best one to use for X. Do yourself a favor and try not to get caught up in that. You will rabbit hole really quick and it really isn't worth it. As long as you don't go super cheap and you did your own research on the stuff, the little stuff shouldn't make you bash your head in because the stuff that most audio guys fuss about is either nonexistent (no real proof) or it's for someone with a much higher expectation than the average user.


You don't need $5000k to have a great sounding system but you also need to adjust your expectation to fit your budget. The one thing I have experienced in all of this is being able to see how big of an impact a good tuner can impact a system. Sage at Sounds Good Stereo is one of those people with "the ear" and he can make a budget system sound absolutely phenomenal with just a DSP. A good DSP and the right person to tune it (the right tuner is the really key component here) will allow you to extract so much more from a system without. At the end of the day, YOU need to be happy with your system. Sadly, I feel like I am constantly messing with it on a monthly basis because it "sounds off" and I really just think it's aging + losing it. 


Just wanted to chime in and leave some information since I haven't been on here in a while. I left some recommendations revolving around DSPs as I had gotten some questions about them and I really think they aren't given enough credit because of their steep prices. A DSP can not only last you a very long time but it adds a ton of flexibility that can also help make the process of changing/upgrading speakers, changing/upgrading amps, or changing vehicles much easier. There are reasonably priced DSP options that many people have lots of success with so don't let the price of the higher end DSPs scare you off completely.


Also throwing in some pictures of my back wall since I saw some posts asking about how everything got laid out.


DSP Tuner Recommendations

  • Sage @ Sounds Good Stereo (Nashville, TN)
    • Sage has worked on mine and I have also listened to their SQ competition car.
    • All ears so you have to go to him
  • Nick @ Apicella Auto Sound (Stony Point, NY)
    • Highly respected in the car audio world and plenty of people/videos/posts to back him up
    • Can do remote tunes to get you setup. Taking it to him would yield better results but should be more than enough for most.


Common DSP options are:

  • Helix DSP 
    • Mini (6 channel)
    • DSP.2 or DSP.3 (8 channel)
    • Pro Mk2 (10 channel)
  • Mosconi DSP
    • 4to6 (6 channel)
    • 6to8 Pro or 6to8 Aerospace (8 channel)
  • JL
    • TwK-88 (8 channel)
  • miniDSP
    • C-DSP 6x8 (8 channel)
    • C-DSP 8x12 v2 (12 channel)

Got everything done with yesterday. Unfortunately they did not take a pictures. I have spent the last several hours throwing every type of music i can at these subs with the new VX amp. Have not had a single hick up yet. I am ecstatic with the sound system again. It could have just been a bad JL 750 HD amp. But since i moved up to the VX1000 i am beyond happy.

So here is what I am thinking about

Hybrid Audio Technologies Unity 6x9 shallow midbass $400
Hybrid Audio Technologies Unity 3.7" wideband $200

JL Audio VX1000/5i $1300

Navtv interface $600

MTI dual 12" sub box with 12w3 subs $1100

Install hardware / sound dampening $300~

I am planning on toslink cable from the NAV TV interface into the amp and then running the front stage active 2 way with the internal DSP on the amp.

I think all in all it will come in about $3400 for everything

What problems did you have with the hd750/1 I’m having issues with mine in my at4. I’m to the point of selling my complete JL stealthbox and amp and starting over. I have a stealthbox and hd750/1 and LC2i everything else is oem. The signal to the stealthbox is terrible would adding a DSP fix this or a different loc? I paid a Best Buy installer off the clock to install everything works as it should but sounds terrible for the money I paid for amp and enclosure should sound great. Any help would be awesome thanks.

The 750/1 kept clipping and shutting off. The VX amp works way better than the hd amp did.

I’m not having that problem. I think the lc2i is wired wrong looks like he took signal from the rear door speakers and not the factory subwoofer so the signal going to the subs is full range they are playing music and not just bad like they should. I need to access the oem

sub wiring and try to rewire the loc.  If wired from oem sub should only be one set of inputs?

You can split the subwoofer signal and use both inputs on the LC2i. The rear doors are the worst place to get signal from in these trucks(and most GM's for that matter).It's not full range I guarantee that.Probably bandpassed from like 150hz to 2000hz. I'd like to get into one of these and go through the outputs with a DMM and test tones just to see how Bose sets up the processing in that amp.

      Hello everyone, first post here
      I got a problem a few days ago with the sound on my Silverado 2017 z71 reg cab, the two door speakers just stop working. i checked the Amp fuse and the radio fuse and they are fine. any suggestions?
      Thank you

      Hi I am new here so I'm not sure if I'm posting this in the correct spot, but I'm having big electrical problems with my 2018 GMC Sierra 1500. it started about 1.5 weeks ago, I turned my truck on one cold morning(-15C) and my speakers were making crackling noises with no music coming out at all, no door chimes or signals either. I noticed my volts were around 15.5-16, but it never went over 16. the music would come back on when I turned the engine off and just had it on ACC mode. I called my mechanic and he told me it was probably my alternator, so I paid to Get that replaced, he returned it and nothing changed. still having the exact same problems. I called him again and he took it back in and looked at it some more. The speakers now crackle for the first 5ish minutes of the vehicle turning on, and then eventually smooth out as the volts settle down to around 14.3V. I put in all new speakers around the truck about 6 months ago, with an Amp and subwoofer, but I am just now experiencing problems with it. I tried taking the power cable off of the amp, and its still doing it to the door speakers and tweeters. I am now out $1100 and still having this issue, if ANYONE could give me some advice or something I could try that would be awesome,

      My battery died in my 2017 Tahoe, and I was able to jump start it. However, I now have no sound from my radio. It powers on, and I can play songs from my phone through Bluetooth connection.  
        Any ideas what's wrong or how to correct this?

      For those of you looking to setup your own MultiPro tailgate speaker system, well HERE YOU GO! Wiring harnesses and amplifier brackets to make your project super easy!! No splicing or hacking away at your expensive factory wiring! I have a limited number of the items in stock, 10 or so of each, with more that will be ready next week!
      When I did mine, I used the Soundstream ST4.1000DB bluetooth amp (and I am very pleased with it so far), so all of the options are available as plug and play with that particular amp. Or you can just get a harness with a pigtail that will give you 12v+ power and ground in your inner tailgate, so you can wire it up to whatever you want. Don’t forget to check out the options for adding lights and the speaker wiring harness to make the whole system truly PLUG & PLAY. so much better sound than the Kicker system for a lot less money!
      All items come with complete installation instructions (with pictures, ha)!
      Let me know if you have any questions!
