I've documented how to replace the Tesla rear door speakers with lots of pictures and a frequency analysis before and after. This project will work on any door, but for cars without Sound Studio, the rears lack much punch or high-end.
The project is non-destructive. There is no visible difference, and no holes or cuts are necessary to the car. Wiring work is also trivial.
The end result was a little less dramatic than I hoped for, but it does improve the sound. Perhaps the next project will be amplification to give it a bit of extra kick!
