2020 GMC Sierra New Audio System

After cutting a lot of the foam off the back seat, is the interior a lot louder?

[@JMSAudioSTL]

Nope. My truck is loud with my borla Atak exhaust. So before the foam all in and out. Sounds the same

With the zen is everything plug and play would I be able to run epicenter with zen

[@JMSAudioSTL]

You’ll bed to ether cut the Bose amp wiring harness and plug it into your epicenter or just get a 4.800 and it had the built in dsp. Just like a epicenter. So you don’t have too much back there

[@willthatsall]

Any issue with the ZenTV? That model is currently not for sale on their website because so many people were having problems with it. There seems to be no amp bypass module available for those GM trucks right now.

[@JMSAudioSTL]

Nothing wrong with it. I know I updated firmware 7-8 months ago and it’s been fine. I’m glad I got it before everything

[@lilramos2012]

Were/are you running this off of the factory head unit?

[@JMSAudioSTL]

Hey with the Bose factory system I have eliminated it with the NavTV module. That is giving me all my signals I need to feed to my 4.800 amp. I had a guy make me a custom harness so no cutting factory amp wiring. If need any more help. Please reach out to my audio page or give me a call 314-341-1266 m.facebook.com/jmsaudioSTL/

[@lilramos2012]

@@JMSAudioSTL OK yes I am planning to do the same thing right now I’m just running 2 12 under the seat through an LC2i converter but when checking the output of the factory head unit with the SMD DD1+ the radio is distorting at volume 36 if you count clicks out of 63 which kind of sucks so I was looking into possibly changing the head unit but really can’t find much for 19 GMC 1500 Denali seems it’s either 14 through 18 on the 1500s And 14 through 19 on the 2500 s Still looking into it but haven’t had much luck On why all the kits are labeled that way would hate to order it and have it not work

I have a similar setup im having trouble by hearing the turn signal and seatbelt chine amplified through front and rear speakers what do you recommend to not hear door chime and turn signal through al speakers?

[@JMSAudioSTL]

Hey you have the NavTV box? Could be a setting also You have the audio control 4.800? Setting on the software on the computer when your tune it If so it does make it as loud as factory. But if you have volume up you can hear it faintly If need more troubleshooting text 314-341-1266

[@fredp8388]

can 6x9 fit in the rear doors? and do you have a DSP?

[@JMSAudioSTL]

Hey the 4.800 audio control amp has a built in dsp. I was assume so that you could do 6x9 on rear but the speaker bracket they offer is for 6.5. Could make something

[@fredp8388]

Where is a good ground point for this truck?

[@JMSAudioSTL]

So I used the bolt from the seat. Where the two seat belts. If you pause in first 5 seconds you can see the ground wire ran behind it. Make sure to sand down to metal My terminal of my 0 gauge I had to make hole a little bigger but I had enough material still to tighten down.

[@jameslavinder4368]

What screw or bolts are you using to hold the amp rack up. And what brackets as well.

[@JMSAudioSTL]

The brackets are just radio brackets that were in a radio I installed for someone. The screws are just self tappers Phillips or hex head The board to hold the amps, is pvc board

[@jameslavinder4368]

@@JMSAudioSTL ok did you have brackets for the bottom as well. I’ll be using 1/4 mdf for my rack just wondering the screws. Did you have to cut a lot of the foam out.

[@JMSAudioSTL]

Foam I cut it all out. Besides the ends. The pvc board what I did was. I took all the amps and converter off back wall. Then I press in gentle into the studs on the the board to get the factory locations and used the same bolts. But in the top I didn’t like the flex I was getting. I used those brackets to give more strength

[@jameslavinder4368]

@@JMSAudioSTL ok but with the foam out does it make the seat feel weird or flimsy I have a 14 yr old and a 5 yr old do one is in a car seat and the other is not lol just curious. I have cut out some but I didn’t take it all out didn’t want it to be to flimsy.

[@JMSAudioSTL]

No the back of the seat isn’t supported by that. That’s for the louvers on back wall so you don’t hear the noise that much

[@laleydeiguala6367]

Nice how much costs to due all hard work

[@joeyc4083]

curious how much was it all together? and did you build the box?

[@JMSAudioSTL]

I had a guy build the box. Roughly around 600 for it. All equipment and can’t count my own labor. But equipment about $3,500-$4,000. Could be high but around about. Labor would of been another $1,500-2,00.

[@overtimesportzot8747]

What made you go with the sundown components ? Have u ever listened focal flax ? Would u go with focal over thanks I'll be reaching out soon when my new truck arrives for your assistant thanks

I have. just at the time they were hard to get. local shop is sundown authorized dealer. so got great price on them. probably would change in future. if need anything on your truck. question or anything. call or text 314-341-1266 I have taken almost every panel off. so yeah 😂

[@DavidRodriguez-zq4ie]

I’m using a module to retain all factory controls but I have lost the ability to use the factory wireless phone due to only getting audio from the super tweeters. Have had this problem.

[@JMSAudioSTL]

Nope

[@cotx79]

Goals!!!! I love audio control but they’re out of my budget currently! Question, you running factory stereo or aftermarket? If your running factory stereo, did you tap into the wires between the front and rear door? Or did you tap into the front door speakers for your bass? I’ve read that tapping into the door speakers gets your a better full range signal for bass cause that speaker gets a fuller signal since it’s a bigger driver than the rear door speaker. I have mine tapped into the rear speaker. I wonder how much better the bass would be if I did the other. I have an audio control lc7i with my factory head unit.

[@JMSAudioSTL]

Hey. Factory radio. Also getting connections from the rear from Bose amp. The nav tv is giving me the signals to the audio control 4.800. The 1500.1 is getting signal from the 4.800 amp I’m not pulling from factory sub. It’s all ran off 4.800 and tuned on the app they have

[@viktorfrankenstein1240]

El cl7 te sirve para ponerle amp alas voces y amp alos bajos tambien?? Wl lc2 También funcionaria?

[@hugomolina3522]

I have the same setup on the amps, how did you do the amp rack That the only part I’m having trouble on

[@JMSAudioSTL]

hey sorry for late response. it’s a abs plastic board that I used factory bolts that held the Bose amp and outlet converter. kept it between the vent in cab. just a lot of measurements before cutting

[@cgingermany]

I'm about to do my 2022 LTD but I was curious to know if the amps get hot back there.. What y'all opinion?

[@JMSAudioSTL]

Not hot at all. A lot of the foam of back of seat was cut. So it’s getting air flow. I have a newer sub amp a crossfire 2k on two crossfire 8s now. So moved things around some.

[@JMSAudioSTL]

I’ll do a updated video with the new stuff. Same electrical components. Just bigger sub amp and subs. Same box too I’ll probably be changing out the door speaker amp shortly. I have the crossfire components in the doors now. Way louder and crisp

[@dylangarcia9492]

How is the electrical system handling the 2k watts. Any dimming? And what does your voltage drop to when bass is hitting hard?

[@dssrbremer]

Nice 👍

[@JMSAudioSTL]

Thanks ✌

[@andyh8239]

Are you using high level outputs for your signal (amp input) ?

I’m getting signal from the 4.800 to the 1.1500. In the software It converts it for me.

HeyJohn great job but I have a question…what about the heat produced by the audio control….seats will be covering them

Great question the foam padding has been cut and the air vents on back wall when driving actually lift up and let air in and out. Also plenty of space for the amps to breath. With the floor vents. We get some crazy heat in the Midwest. So never a problem

If you're still getting water back there check your rear glass. Some of the rear windows on the 2019 and up Chevy and GMC's are known to have problems with leaks. I recently bought a 2020 Sierra and so far so good. I looked at a 2019 and there signs of the rear window leaking. The storage compartments in the rear seats had water in them, so I walked away from that one. The good news, if it's still under warranty the dealers are repairing/replacing them under warranty. If not under warranty there are several good repair videos here on KZbin.

[@JMSAudioSTL]

Yeah dealer fixed my rear window leak. But the louvers on back wall aren’t tight. So I used the window gasket around. I actually just swap a amp out and nothing damaged. Moisture still gets in from the louvers. But it sits 4 days a week. So yeah

[@Baz1122]

How can I make my truck sound better it has the regular speakers but the sound quality just sucks can’t even have it loud cause it sounds scratchy

[@JMSAudioSTL]

Hey I would recommend. Swapping interior speakers. Then better headunit. Some cars can’t change out. But depends on year make and model

[@JM-kn9dh]

I like the setup a lot, the amp rack looks very clean. I do think however that the wire could have been cleaner.

[@JMSAudioSTL]

Appreciate it. With these trucks back seat and mounting brackets. Running wires a certain way so over time no pinching will happen.
