Tesla Model 3 RWD 2023 - Audio Upgrade

@Arthur Cheung It has been documented/talked about here: Hansshow premium audio upgrade for 2023 M3SR I did it for my 2023 model, and it went through pretty well. Took about two hours because I was pretty careful about doing it. The best analogy for how it sounds/improvement is... before you upgrade it sounds like just two speakers in front of you facing straight ahead. After the upgrade, it sounds like the speakers are a little further apart and a little higher up. Helps with the stereo separation I guess is the best way to describe it.
The RWD is definitely a decent platform for upgrades. I’m sure a kit would make a decent upgrade. Depending on your budget and desire, there are some healthy gains attainable if you piece it together.
The hardest individual step in my upgrade would have been taking the car apart enough to install the hansshow diy speaker activation harness, to which I made a few modifications .

Has anyone installed the basic wiring harness to activate the 4 extra speakers? The kit I received appears to be for lhd cars? The new harness is supposed to be only one side of wiring but I can't figure out if it's the drivers side or passenger side. I took the panels off on the passenger side and it looked different than the video on YouTube (but that was a lhd).

No, it’s a car. A big steel box is not a good place to get a decent sound. The stock sound system is adequate for listening to entertainment while I drive home so I can really listen to music on a sound system in a balanced room.
Did you just tap in to the penthouse to get power to the amp? I suppose you have the RWD with the AMD Ryzen?
I been reading your post over the last couple of days and it may have slipped past me..
I'll be adding the OEM sub and the Alpine KTP-445U
The modification of the hansshow harness seems easy enough it's just the damn power that i keep seeing conflicting answers to. 12V, 16V, penthouse, not penthouse...
You are correct, I have a '23 RWD/AMD.
The biggest thing to consider is an amp that's rated to (and ideally beyond) 16V DC on the input. I'm sure there is a limit on the amount of current that can be drawn from the penthouse low-voltage terminal before errors or other issues occur. I haven't had issues yet using a very efficient 500w amp (Kicker Key 500.1 at 1ohm) I used a generic Crutchfield 8awg amp kit. The power cable is very short compared to a normal car, and the ground cable is incredibly short if using the factory amp ground next to the sub.
Hope that helps, the hardest part of the installation is removing trim panels without breaking any clips. Good luck, it's definitely worthwhile!
The sub is good, I'd like to try an Image Dynamics IDQ-8 V.4 D2 but I've been too busy to proceed with that yet. I also have a JL 10" that would work in the enclosure so I may see if I can print an adapter to fit a 10" woofer in the stock 8" enclosure, not sure if it's possible yet.
did you modify the harness to add the sub? if so is there any way you can provide a tutorial? im trying to add a sub to the harness and would like to use both left and right signals from the harness. thanks
@RWAudio how are you finding the frequency balance with your set up? With the Alpine DP series its incredibly detailed but probably overly bright and fatiguing, I’m looking at the tweeters as the culprits. Turning the highs down with the EQ is ok for almost everything but phone calls seems to bypass the EQ and sound terrible.
I notice you had a look at the Hansshow kit crossovers, did you make any alterations to them? I’m thinking of making an L-pad to knock the tweeters down about 5 db. But curious if there are any other solutions.

I just discovered your posts in this thread which were very enlightening:

I wonder if your resistors were wired incorrectly as I have the same Hansshow harness and can hardly hear the upper pillar speakers.
I'll experiment with disconnecting the tweeters and see how that affects the phone call experience. Its so subjective between highly detailed and fatiguingly bright, I found myself putting the treble back up a 1-2 dB this morning which made a song come to life a bit more. Decreasing the tweeters compared to adjusting the EQ would be interesting as the high frequencies would still go to the dash speakers so maybe reduce the harshness but not the overall clarity perhaps.
I've been doing some pink noise tests with an external mic and there's a bit of a spike around 8 kHz which would be good to tune out.
Hansshow premium audio upgrade for 2023 M3SR
I installed the Hansshow harness recently in my RWD 23. It is working fine. Watch this YT video to double check your connections. That's an awesome video! Glad that more videos are coming out for how to do this. I was too afraid of breaking things so I didn't try to take off the entire long...

At the moment I have the focal IS200 set installed, and I can't say I'm fond of the focal tweeter it's also a bit bright with certain music. I like their utopia stuff, but I'm not so fond of lower-tier focal.
I hope to switch back to the Hertz set when I get a chance, maybe even just the tweeter for comparison. As for the L-pad, that shouldn't be too hard, and shy of disconnecting the tweeter (RWD cars don't have tweeters hooked up) that's about your only option. I may try disconnecting tweeters as an interim step before I swap in the Hertz tweeters.
I’ve gone back to the Tesla tweeters and they sound pretty good with the other upgraded speakers. They’re soft dome, looks like your Hertz are too so I’ll look for a soft dome as a replacement I think. They say that metal dome tweeters are great for piercing through a lot of background noise and I don’t think we have need for that in our cars!
Some tweeter sets come with crossovers with attenuating switches, but I wonder if there’d be negative effects of putting this after the Hansshow crossover. So maybe the long term solution would be cutting that out.

Was thinking of doing it but a few updates ago, the subwoofer finally turned on and it sounds much better.
