Activate 4 Speakers for $39 on 2023 Tesla Model 3 RWD and 2022 SR+ 

Big thanks! I watched your video once before the installation, and played it as I attempted the installation successfully! Took me about 45 mins from start to finish. Getting that first harness clip back in is VERY tricky. I had to contort my body a lot to get a good angle. Definitely want to put your passenger seat all the way back. Thanks again!

I did this about 2 months ago, wish I had this video when I did it. It took about an hour, but def had to double and triple check everything to make sure I was doing it correctly. Very glad I did it, it improved the imaging and treble of the sound system by a ton. Well worth the $60 and time it took! Great vid.

Thank you! I got mine done after looking at your video. Totally worth it for me.

This is the only video I found that knew exactly what to do on the 2022 Model 3. I would have never figured the driver side audio was connected on the passenger side lower sill area where you used the wood to help hold it out.

Best video for doing the installation of the harness! Many thanks!

Best video I have seen so far. Really need to see the new harness install. Thanks sooo much.

Thanks so much, this is the video to use with the latest version of this wiring harness and the 2023 version of the Tesla Model 3

Hi, I'm French and I bought the audio upgrade one week ago, but I was stressed to do it. Your video is very clear, precise and reassuring and so I will try next year. I will telle you about. Thank you

2 things that might help that weren't mentioned. 1) Move your passenger chair back before taking out the battery 2) the harness with the swivel lock needs to be pressed in in order to unswivel it. There's a small area that clips it into place. I used a punch to push it in and then it swiveled. It took me about 30-45min from start tot finish. It would have been faster if the swivel didn't hold me up.

This was the video i was looking for , finally found a perfect installation...it was a pain in the butt plugging that harness under the dash board coz was super cramped with those wires and the passenger door to settle the harness in … my car sounds awesome now wow big difference!!!

Thanks very helpful info, i will order mine now. Thanks

Thank you for the video. I was under the impression you had to connect the harness under the dash on both driver and passenger side. You just saved me a lot of effort. Looks like it’s just the area under glove box and right side B pillar lower area.

Thank you very much, this was very helpful for my install. The only struggle was the Black plug spot, it was not plugging in easily. After an hour of try, I had to scrap a bit of the the kit’s plug i order to fit in! Overall satisfied with the results!!!!

Thank you very much. This helped a lot

Fantastic help! I just installed it today. Sounds great! Would've been much more difficult without your video. Well done!

Helpful video, everything was exactly as shown on my 2023 RWD. The bug battery didn’t disconnect immediately for me when flipping the lock, and it was slightly difficult to get the plug into the computer. Otherwise, pretty straightforward. I immediately noticed improved imaging when I turned on the music. It was worth my time.

Great video! Just installed this and was super easy. I have not had distortion issues at high volume like others have said. The highs sound way more immersive too

Just did it on my 2023 RWD, took me about 30 mins (only thing was that I broke a small plastic tab that holds that swing down bracket), everything else went smoothly, overall was an easy process + thanks for the video. To be honest I didn't notice too much of a difference. I can hear all the speakers playing. I try different type of songs.

this will be key in helping me in my mod, great work

Is there still only one side to remove the panels from on the 2023 right hand drive? Thanks, great vid!

This was super easy thanks to this video. The only thing that I spent some extra time on was the new clip on the side of the silver controller. Other than that, very well explained. Thanks!

Great video! Have you noticed any difference in max volume? Or does the amp automatically take into account the extra power draw from the 4 speakers. Thanks again!

i did this a few weeks ago, the first plug is so hard to get too, but took around 45 min to do. would recommend, but as expected, bass is still very bad

thanks, I compared with another RWD 23 car without it using same song same volume, there's clear difference, sound is closer, and highs sound brighter. if you are here watching this awesome video, you are interested in the sound upgrade, it's worth the effort. Installation was not bad, just difficult to maneuver in tight spaces. the hardest one for me was the b-pillar, even with the door seal pulled out and moved out of the way, space was tight. Result was pretty good, no bumps on the floor, or loose wires

Thanks for the coupon code! Just ordered this and will be using your guide once it arrives.

Hey! Thanks for a great video. I'm just a little confused near the end with the final connection with the blue end. Was the blue end connected to something before you attached the new harness? And where do you connect the final end after you connect the second last piece to the blue end?

Hey. I am thinking about doing the razor sx500 1800w build that you did but want to see a top speed and acceleration test with a gps phone app. if you could make an updated video it would be greatly appreciated.

Any idea if this would influence warranty when you bring in the car for issues in the future?

Did you order the DIY (new version)? I saw another video where he installed a connector on the driver and passenger side. Does the new version only require access to the passenger side?

What do you think about it decreasing the impedance at the ICE, since the speakers are wired in parallel?

great video btw

Going to assume this is the same process for the Right hand side 2022 Model 3, with everything still being in the same spots? Great vid, thanks :)

Thanks for the video. I just installed this kit in my 2022 M3, and it works well. However i noticed, that the audio is a little louder on the driver side than on the passenger. Did anyone else have that problem?

Got mine done today - took a bit of patience but all connected as described and sounds great.

B Rich, I am a little confused about Model 3 configs. The Standard RWD model has 4 speakers disabled or two pillar speakers disabled and no Subwoofer? The model 3 SR Plus has additional rear speakers? the model 3 LR has sub woofer?

I have a 22 MYP. Aren’t the pillar speakers for the immersive sound which is something that RWD and SR+ don’t have?

Are the connectors on the 2022 and 2023 Model 3 the same? I ordered a harness from a different site, it said it worked with a 2022 model 3, but the black connector from the box does not match what's on the harness....trying to figure out if 2022 and 2023 are different and I ordered the wrong one, or if they're the same and the seller misrepresented their product.

Great video. Anyone have had problems with the bance on the speakers?

Did the addition of this overload the small speakers and distort when at loud volumes?

So activating this speakers means almost the same as the more premium system. What left in compare to the premium? the amps and the subwoofer right?

Thanks alot , I have model 3 2023 rw , car info says that i have premium speakers no external amplifier, and the 4 speakers are not working, should i install the harnesses or my problem is something else

Do you know how this will affect me if I want to setup a subwoofer later? Or will I be okay to do this now and then doe the subwoofer later?

is disconnecting the batteries necessary? I've seen other video where the installer didn't do that..

Great information this could be my first electric but don’t understand why this isn’t done from the factory?

Thank you very much.

Does this add any bass? Ik it would be like an actual subwoofer but a lil something would be nice

Do the 2021-2022 RWD / SR+ have the speakers in the A pillar?

I've got a 2018 M3 with the premium audio upgrade already. Is this still needed?

I just bought a 2023 RWD 2 weeks ago. Manufactured 5/23/23 so it's brand new. Has the AMD. Will this work? On the website it says 2022, nothing about the 2023 and will i void my warranty at all????! Thanks a bunch!

Thanks for the video, I did this last week on a 2023 M3. Getting to that black connector under the dash was pretty hard, I had to get the wife to help because she is smaller than me and has smaller hands. Once we sorted that one out, the rest was relatively easy. Although it is hard to properly fit the extra connector under the trim on the B pilar. I managed to fit it in, but there is a small bulge under the carpet next to the seat. It does not interfere with the seat operation, but I don't like it. Speakers are operational now it feels like too much trebble 😂. Sounds really good. Now I want the sub 😅 and rear speakers. I wish there were some guidelines as to how to tuck all the thick cable away under the B-Pilar on your video. You sped up that part ! 😅 Anyway, success story for me and thanks again for the video.

Tesla recently put a software block in place for at least the 2023 models. As noted from a recent post: Just came from Hansshow Tustin California installation/service location… Was gonna buy and let them installed this on my 2023 M3 SR… They told me that they won’t be able to install it coz they just found out that TESLA planted a bug that when those 2 pillar, 2 side mirror speakers are activated by AFTERMARKET Harness.. Bug will make them speakers muffled or static noise..: So they told me to hold off till they find out if there is any solution they can do🤷🏻‍♂️

Excellent! Just finished and everything went well. Pointers: watch the video through before starting Don't rush - plastic scratches and breaks Put passenger seat all the way back before power down Use a flat head to push on side of clips to release them After pulling the black clip that's hard to reach, connect the replacement white before connecting the original black to the harness The hardest part for me was putting the new white into the computer box where the black had been.

Why aren't they activated to begin with? Is Tesla still charging extra to activate all speakers for the premium interior?

OK so got the kit, got everything connected until I got to the pillar connections at the driver's seat which were not there. Had no luck and nothing. Would these be located somewhere else for a RWD 2023 car? Would you connect the last 2 possibly into the driver front part?

Does this work with 2020 Model 3 RWD ? UK, Right hand drive. Thank you

Awesome :)

0:23 so I have a question about when you said it works on the 2023 and back, since I have a 2021 Model 3 SR+, will this $59 version work on my Tesla? If so, I’ll grab it today and be sure to use your code. Best 😊

So just to be clear, for 2022 SR+ order DIY new version?

So if I’m ordering a 2023 Model 3 RWD now, which harness do I order? Thanks for the video, it would have taken me forever to figure that out.

Will this void any warranties potentially? Thanks

So the model 3 standard range do come with extra speaker but not activate?

I've seen a video of this kit, where you also have to plug something in on the drivers side.. Is this no longer the case?

How about the warranty? will it be still valid after this mod?

I installed the harness and the front left side speakers worked fine but the right side had no sound, including the original active factory speaker. Trying to contact Hansshow to determine if it is a defective wire harness.

Did you just assume that you have to unplug the 12v battery or it's actually confirmed that you would get fault errors? I would prefer to not mess with the battery

Just did the install. The new speakers sound is pretty minimal, most is still coming from the front speaker. Is this the case? Should I be noticing a huge difference? I have to hold my ear to the speaker to try and hear sound

Doesnt this mess with the speakers because theres less power for the rest of the speaker. Does this void warrant?

Would this work for the 2020 RWD M3?

I have a 2023 model, this one has inactive back speakers? Or just the 4 front?

I tried 3 differing cables in my 2021 SR+ however none matched. I have a 2023 arriving in a couple of weeks - now I have the video will try again

Do this work for a refresh model 3 as well? I have a 2021, the amazon product only goes from 2018-2020

Which version do I get for a 2023 model 3 RWD? DIY (New Versión) LHD or RHD

How many hidden speakers in 23 Model 3 RWD? Some says 4 and some says 6?

do all Tesla 2023 model 3 RWD have the inactive speakers. I heard rumors that they have been removed

I have a 2022 M3 Long Range, are those 4 speakers off for only the lower models? Also if anyone knows, why were they even off?

also, does this kit with 2023 Model 3 SR?

That first plug was an absolute Muther to install!!!!! Sound like most other tubers mentioned is subtle but there nonetheless. Wish I had a sub though. But that is a wee expensive to do…..

I bought a 2023 Tesla model 3 RWD and got it in the middle of March. Does this already have the speakers activated? It doesn’t sound like it but I want to make sure before I tear the car apart to put the harness in. Also, has anyone had any issues with the warranty getting voided due to this harness install?

So on a right hand drive would the connectors be on the left passenger side?

any idea why those speakers are even there if they're not activated from the factory? Are they reserved for a higher trim package or something?

Hello! I believe I have received a faulty kit and emailed hansshow about it. Is there anything else I need to do on my end in order to receive an exchange kit! I really want this to work and was wondering if you had any ideas. Thanks!

I had this one on my 23 model 3 rwd. But passenger side top speaker is not working. Any iideas? Please help!!

I am confused. Why aren't they active? I have a 2019 M3 SR+ Intel atom and have Premium speakers and no external amplifier. Does this mean those 4 speakers aren't active in my car? Please help me understand so that I can purchase this.

Does tnis void your warranty?

Does this affect the warranty of the machine?

Does it work on Model 3 SR+ with the amd ryzen ?

Question, after I watched your video and ordered the cable from your link and installed it, it was working great for about 2 weeks Has any of your followers had any issue with either side? Stop playing cuz right now the right side stopped working all of the tweeters did on the right side

Does this still work? I heard Tesla sent out an update that disrupts this harness

Just bought my Model 3. So this needs to be done for the speakers to work?

Would this void any warranty?

I'm buying the Long Range, or Performance. But somehow I stopped and watched this video anyway. Thanks for sharing.... lol

Is there any danger in removeing the high voltage power under the rear seat?

I had a serious issue with the newest DIY design. It almost muted the driver speakers. I put every back and was testing the balance. Very low, distorted sounds coming out from the driver side speakers. I wouldn't recommend installing this. What if it overloaded the amp and fry the primary computer as well? Also, 90% of the wires are all gray, no color coding. How on earth they put them together? Very high chance of cross wiring.

Hi, the link to the harness no longer works. Also, are all M3s equipped with the non functioning speakers?

Is there a way to enable the sub?

Does it improve the sound at all?

This does not include the speakers in the back and a subwoofer. Is there an easy way to add thise speakers?

Does this apply to 2024 RWD? I’d buy

Can you do the footlights also?

Installed the harness several times. Harness failed to activate the 4 tweeter speakers
