I have a 2019 Model 3 SR+ and audio is one of the things I've been upgrading. I connected the unused speakers with a wire harness, installed the NVX boost and just installed light harmonic front door speakers.
But with the light harmonic front door speakers also came an upgraded 8" subwoofer that fits the OEM sub if you have premium audio. Are there any boxes out there made for Model 3s that go in the sub trunk? Or would it be possible to buy a used OEM subwoofer box and put this sub in that box and connect that to the amp used to power the NVX boost? I don't know much at all about audio.
