    Thanks todd2fast4u!
    Wife has a 2021 model 3, got the tesla offer activation kit with the rear speakers.
    Overall a very easy install after watching the install video. Rear speakers were the trickiest part.
    Overall can definitely tell a substantial difference in the sound quality. Door woofers sound the same. To show my wife the difference, I would unplug and replug the rear and the front speakers for comparison and definitely a buy. I have the model y and she was bummed about the difference between mine and hers but she is happy now!

    89$ for the harness and subwoofer wiring. Didn't installed it yet, still looking for a dsp, amp and subwoofer. I was planning to use NVX but they don't schip to my country.

    Should I get an amp to power the newly activated speakers? Or will the oem amp be sufficient still? Not doing the rears just the fronts.

    I hacked up the Teslaoffer harness and fed the front mids, front doors, and rear doors into a Helix V Eight DSP. I'm powering the Front Mids, Doors, Front Tweeters, and Rear Doors with the DSP now, and using the line outputs to run a seperate sub amp (work in progress). The Helix DSP is amazing. I've done just a tiny bit of tuning and the system already sounds waaay better than stock even without a sub installed yet. I am not running the center channel or the A pillar imaging speakers. Don't really need em.

    Those of you using the Alpine KTP-445U amp to power the additional speakers, where are you locating the amp? I have my harness and stuff and i'm thinking through where to put it. Did you put it up in the dash?
