Model 3 SR+ Speaker Activation
$79.00 – $209.00
With this wire harness, you can activate the 6 inactive speakers on SR+ (only 4 in post-March 2020 build) cars.
The work is done by connecting the front dash speakers parallel with the tweeter and A-pillar speakers to feed the signal for the speakers, and connecting the rear door speakers in parallel with the rear shelf speakers.
If your car is built post-March 2020, you can choose the option to add the 2 rear speakers (it will come with 2 OEM used speakers for you to add it back to the rear shelf).
If your car is built post-October 2020 (Model Year 2021), you will need to tap 2 wires to enable the front right tweeter (the plug-and-play connector is removed). Contact our Tech Support for more details before you purchase.

Works pretty good, actually surprising well, although the video was not accurate with the location of the passenger side location for the tweeter wire.

The new revision version would be simple to install. SR+ owner should install! Strongly recommend!

I just finished installing this on my 2019 SR+ LHD. I purchased the harness in December 2020 so I have the latest revision which does not require routing a wire to the driver side. Everything is connected on just the passenger side, which makes things way easier. I allocated an hour for the install but it actually took me closer to 2-3 hours. It’s not technically difficult, but it requires a lot of dexterity and getting panels off and on can be really challenging. Here are some tips for would be buyers – the hardest part is getting the first connector, that goes into the MCU off. You have to push a button and pull but it’s really hard to get a firm enough grip. You don’t appreciate how small of a space and how awkward of an angle it is. It took me maybe 30 minutes (really) to get this connector out. What didn’t work: Using a tool in each hand – one to push the button and the other to lever the connector out. What worked – without looking, reach under the dash and push the button with one hand and grab the whole bundle of wires and pull. There is almost no space here. The next problem I had was the length of wire from the front area to the B-Pillar. You can think of the harness as three parts – MCU/Tweeter connector, B-Pillar, Rear Speakers. In the video, they make it seem like the B-Pillar to the rear is the one that is a tight connection. It is but the one that is really problematic is the front to B-Pillar. And because there’s a connection in the center, doesn’t make much of a difference if you create slack on one end or the other. This causes issues because you can’t neatly route the wires and in my case, I had some taut sections that were in danger of getting snagged in the clips for the trim pieces. Lastly, this might be just an issue with mine but when i removed the black B-Pillar trim, I knocked the seatbelt adjustment mechanism off its “rails”. Everything seemed fine but when I put it back together, I noticed the adjustment would bottom out higher than before. This is not something you’d notice unless you look at at the driver side or just “know” how far up and down the adjustment goes. This took me half a dozen tries of taking the whole B-Pillar apart and put back together again to solve. The assembly looks simple enough but as you can imagine, most people have never seen the inside of the assembly and it’s not obvious exactly how things should be working. Finally, in my first attempt, when I was done, I noticed that there was no audio on the right side whatsoever. No fronts, mids, rears, nothing. YI highly suggest testing this yourself by moving the balance left right, front back. I fixed it but just pushing on all the connectors. I didn’t even change or reconnect anything.
So was it worth it? Yes – even if you were used to the audio in your SR+ and it sounded fine before, having 6 additional speakers makes a huge difference. It’s almost doubling the amount and locations of where sound comes out. I didn’t think it would be that noticeable (and it’s not as noticeable as adding a subwoofer for example), but you can hear the effects immediately. My only wish was that the wires coming out of the B-Pillar connector were 2-3 inches longer. I think this would add almost nothing to the production cost and tucking in extra wire slack is much easier than trying to get a connector to reach.
