2019 - 2022+ VW Jetta Sub and Amp Install 

Parts used linked in the description of the video!

Thank you!!! Finally someone cover this!!! I have a 2019!

Hey provo, on the close left of the grommett you went thru is the main harness to the engine, there is a little nipple on it that the manual trans viewers can use! This video helped me with my 2020 gli, i uploaded a video showing where the grommett is for the manual trans vehicles!

For anyone who doesn’t have a key set use scissors ✂️ open them and watch your “leathers” !! took me a minute but they worked

yeah so this is awesome, and something i will never undertake myself. great job!

That ground bolt in the back is not a Torx, it is called a triple-square.

My girlfriend just bought a 2021 jetta and I'm most of the way through the install. I just don't see where you set up the remote wire. Unless you rigged it to the lighter socket. Most informative video none the less. Thank you for posting :)

Ive got this exact same set up and 1 8" sub in a ported box, this converter does wonders in my 2012 Kia sorento!! The clarity of this unit, makes my 8" sound a lot larger than what it is!! I love it!!

I love that vw has mqb platform cause this is basically identical to the 2018 tiguan

My 2021 jetta premium sel, sound super hot with the extra bass, I took the sound from the original spare tire subwoofer. This video help! Thanks 😊!

I have a 2024 video definitely helped with taking dash apart and I definitely broke some plastic but thankfully where no one can see, but with the 2024 the wiring is totally different lmao

Awesome instructional, very thorough. I added an amp & LC2i Pro with relative ease thanks to this vid!

I'm pretty sure that seatbelt bracket is a triple square, I could be wrong but VW loves their triple square bits.

you can run the power wire through the firewall with the power harness from factory. there's plenty of room

Same amp I've had for over a year. It's a really good amp.

yo thank you so much 🙏🏼🙏🏼 all i needed was the diagram i can’t find it anywhere!

Great vid but u should of ran a separate power cable and fuze for the lc2i and upgrade them rca 10/10❤

Just bought a 19 Jetta! This is super helpful! Thanks!

Can you tap into the rear speaker output inside the rear doors, right by the speakers? Those speaker cables end up there anyways. That would be a lot easier than taking the dash apart.

This is a great video, but I’m not sure why you would not also switch out the crappy door speakers and the low amperage for them

Can I not just tap into the left/right rear door speakers at the b pillar rather than taking apart the whole dash?

All my warning light came on

Im an amateur audiophile and I work at a VW dealership and I love our cars but both the base 4 speaker and Beats upgraded system are horrible, honestly. I honestly feel like they just deleted tweeters from a 6 speaker setup because it sounds like the tweeter range is just MIA. Treble all the way up and it still sounds muffled. The beats system has a harsh metallic sound and terrible hollow bass that makes the door panels rattle just turned up slightly. The only Jetta system i can tolerate is the GLI S system because it still has tweeters and no sub but sounds better than the aforementioned!

Why go behind the unit when you can the signal at the speaker?

Very helpful and clean set up keep up the good work I use to work on vw over engineered cars friggin difficult to work

This is really good stuff. Not to mention the soothing voice...

Wow. Awesome detailed description and clarity.

You can grab the speaker wire in the b pillar for the rears

GLI owners should use extra caution as to not harm their ambient lighting. Also, now that I see how easy the seat is to pull, I'm going to move my ground to the seat belt bolt. Thank you!

Super helpful video, added a LOC this weekend in my 2020. Boy, that silver dash piece was a nightmare to get off!

I'm trying to tap in from the back speakers which wires do I tap into

I have a 2005 toyota tundra and even this helped me out. thanks bud

can you clarify which speaker wire you tapped.. you said Rear Right and Left.. both positives?? and where do they go on the LC2i? great vid! thanks

How would you recommend hooking up the remote wire for the amp? From my understanding you had it ran from the LC2i to the amp?

Thank you so much for the great video! Best one on RU-vid for sure! 2020 GLI Autobahn!

You can use a 45° pick for the radio keys

Yikes! That Mk7 Jetta dash is a total PITA! Makes me grateful for my older Mk7 GTI layout; plus, the head unit is in the glovebox. Nice work, though!

Them dash clips weren't joking 😂😂 literally why im always hesitant to even tear down the interior want to just to clean better but is it worth the risk

what screws did you use to mount the amp? I'm in the same boat and need to figure that out and did you tap into the fuse for the remote switch? If so which one would you recommend. Appreciate the help

So if I have the 2019 SEL can I tap into the back of the radio that is in the glove department like you did in your golf gti video??

thoughts on the best way to give a vw arteon a better sound--i have it all the way up and it isnt loud at all...

I have a arteon Im waiting for somebody to drop a video on it

Can you tap into the speaker wire already in the back trunk so you don’t have to run wires back to the radio?

I have the 2013 version which is very similar, I heard I can tap into the rear Fender system sub and bridge the LC1i Speaker input does that sound right?

Thank you for this video! Do you happen to remember the size of the replacement bolt for the battery terminal?

Does the LC2i provide more power for the front and rear speakers the way you have it hooked up in this video? In this video you have just a subwoofer hooked up, but you tapped into the front and rear speakers behind the radio? It seems like you should’ve tapped into the subwoofer output. Can you also tap into the rear right and left speaker door factory wires to the LC2i, And then power your subwoofer? Also, by adding a amplifier to the LC2i from the front and rear speakers and then by adding an amp, you’re increasing the power to the front and rear speakers?

So you used RR and LR for the subwoofer, does that mean if I wanted to add a sub and speakers I could only add front speakers since theres only LF and RF available?

On a 2021 jetta I have an lc7i with front and rear speakers tapped to keep the fader functional. Unfortunately one set of speakers that were tapped don’t appear to be getting the full signal and it sounds almost muffled or lacking. I just kept one signal on and disabled the fader on the kicker amp. I checked all channels of the amp and of the lc7i. The issue was recreated when swapping the speaker wire taps into the lc7i. Is there a bad or treble attenuation to the rear speakers?

Do panels make noise after removing them ?

Is there any way to use the line outs behind the rear speakers instead of having the remove the entire fascia?

absolutely amazing. thank you. will this work for a beats sub removal then this upgrade?

Does the factory radio "see" that LOC as an additional 4 ohm load being wired in parallel to the existing 4 ohm speakers and putting a 2 ohm load on the factory radio?

where did u tap in for remote?

Could you tell me what color the left rear speaker wire is ?

Do you have to run wires all the way to the back of the radio if you already have a factory subwoofer in the trunk. Can you just get the signal from the factory subwoofer?

Can someone tell me the part number or where to purchase that positive terminal bolt that he replaced?

Can the AMP+ be connected to an amps remote line? Will that workm

How do you know what you should tune the lc2i output voltage to for the subs and then how much for the amp gain?

Can you tap into rear speakers wires in the trunk instead of going to radio?

Where is the remote wire lead from the stock radio harness .

Just did my install with help from your video. I’ve got no power to the amp, I’m thinking maybe I’ve got a bad ground?

The power wire to the lc2i isn't protected, I'd put a smaller fuse in it. You don't want to start a fire.

could you do a 2008 toyota prius and tips to add another battery in the back? I have everything ready but i cannot find a good video tut on how to connect everything. I have D4S 2800 Rms amp and kicker solo x L7x for my sub. Also i have Lc2i to convert my signal output but i went to a shop and they recommended a generic kicker Loc which idk which one to pick from. Thank you Please update me>!!

Thank you! Awesome video that really helped me. Only issue I ran into is, my Check Air Bag light came on and wont go away. Any ideas?

I have a 2021 and I can’t figure out what the colors are for the speaker wires

Did I message you never showed the subs?

Quick question, do they have ANC noise canceling?.

Hello, I have a 2018 passat. I'm being told I need the lc7i . I have the 8 speaker non fender , factory radio. Looking to add a 5 channel amp and sub with upgraded door speakers in the future .

It appears that they use this grommet position for wiring with the manual trans? Any ideas on another firewall access?

Are you not supposed to use the remote in to the amp ? Why use remote out ?

You didn’t use any control knobs for the amp or lc2?

How did you run the auto power wire?

What amp would you recommend for 2 12in kickers?

Why in the world would you run the high level speaker wires tap ins all the way back to the rear of the radio? That is absolutely ridiculous and defeats the purpose of this high to low level input converter! First of all, he is adding a subwoofer amp so you would want the lowest possible frequency going in as most of the newer audio systems are set up so they don't have lower signals going to the main speakers, the lower signals only feed in to the rear channels or into a dedicated sub channel. 97% of the factory systems have three subs in the rear seat or trunk area. These liner output converters are made to make it easier and more convenient to add subs and amps to factory systems. If your factory system has a subwoofer then you would want to tap into those wires before or after the amp depending on how many watts is coming out of the factory amp. This guy ran an extra 20 feet of wire and caused at least an extra 2 hours of work taking that dashboard apart and in the end will hurt the sound on 2 levels, A) the extra length of wire gives it more opportunity to pick up unwanted distortion and B) may not have the low frequencies needed for the sub. Every single one of these we install gets trapped directly into the factory subwoofer wires or in to the rear deck speaker wires. the only time I tap in to speaker wires in the front of the car is if I'm adding a multi-channel amp and upgrading the other speakers.

Did you have to cut the red wire for the battery ??

I got the 2021 Arteon, is the install similar as this?

can't you just use rear speakers to tap in?

What wire would I tap into for a 12v source that only powers on with ignition? I don’t know which wire it would be. This would be for my blue wire that runs to my amp

is the AMP+ connection where i would splice the remote wire from my amp? @17:01

Do you happen to know the size of the door speakers? Front and rear?

Did you crimp the wire ferral? I can't find a tool to do that except like a $150 one.

Trouble shooting video? Esc, tire pressure, hill start assist, and front assist light coming on.

Will the factory deck support better door speakers?

Is the speaker wire diagram looking at the connector from the front or the back side

any aftermarket radios for these 2019-2021 jettas?

What colers are the speaker wires you taped into

Can you run 2 12s in a jetta or do u need to buy a new alternator

Did you add a fuse for the lc2i?

Is the lc2i needed for this kind of setup? Or is to just improve the bass roll off?

How did you hookup the remote wire

Why go all the way up to the radio when the same wires are at the Center post on both side going to the speakers. ?

Does the lc2i come with a power and ground wire?

What inline fuse did you use?

What is the height of your box?

That’s a lot of work to just get to the radio

Line converter

Why didn't you just tap into the rear speakers in the rear and no need to run cable to front and take the radio apart.

I can’t find anything on my Tiguan. Do you think it’s similar?

Where is youtr store located?

Can you do my car I’m in Atlanta ga
