2022 RWD speaker activation harness modification

[GuitarGuyLP]

I just got my 2022 model 3 RWD. I have seen a lot of threads about the wiring harnesses to activate the tweeters. One thing I can’t seem to find is info on the crossovers. It looks like the harnesses just put a high pass filter on the tweeter, but I can’t find anything about a low pass to the midrange speaker it is in parallel with.

I would guess that the system would sound better with a two way crossover. Has anyone attempted that? It has anyone taken the harness apart to verify if there is a low pass in it already?

It is just a highpass. All of the different versions of cables have been dissected and some are better than others. There are huge threads here detailing them, including mods to make them better.

FWIW, I didn't bother adding it to my 23 rwd. I did have it on my 20 sr+ because it had the rear speakers.

theres a popular one from hansshow, although it took like almost two weeks for me to get it, as it is shipped from China. I have not installed it yet, ill get around to it this weekend.

i got 2 different set of hardness off amazon for my 2021 SR+, they work at the beginning, but when you turn off the car for awhile then start again the front passenger speaker don't work for like 5-10mins then works again. not sure if its because of the software update.

It sure sounds like the quality of the harnesses are hit, and miss. I think I have some more reading to do, and when I get a harness I’ll have to ohm out the connectors to make sure they are solid.

I might try to add a low pass to the midrange speaker, and use the existing high pass to see if that sounds any better than just the high pass to the tweeters. I seem to recall the high pass being 8.5 kHz. I’m also going to be adding taps for a subwoofer.

Just took this screenshot from HS website. Note part I highlighted.

That statement was not there last week when I was looking at it. I think I’m going to avoid the harness for now. I’m leaning towards installing some coaxial speakers in the dash to add speakers that way.

Thanks for posting that.

If you're remotely interested in a harness, contact the guys at EVOffer. At least they have a history of paying attention to Tesla's updates and looking at solutions where needed. They will more than likely have an answer of whether their own harness works with the recent update.

update: i installed my harness from hansshow, ive had it for a couple of weeks now, just updated to 2023.32.1, and can confirm it still working perfectly fine. I really do hope the updates soon to come dont render it useless.

I don't see how an update could render the harness useless. The harness is tapping into the wires that go to from the amp to the speaker. Software can't disable that.

just basing it off of what the website says
