Looking for advice did anyone upgrade the sound system on a 2017 ? And what did you put on to upgrade ?
In brief...
DSP
Mosconi 6to8 Aerospace
Amps
two Mosconi D2 150.2s, and a D2 500.1, this gives us 4x150 on the front stage, and 1x500 on the sub
Drivers
Focal Flax 8" Sub
Morel titanium elate two way component speakers
A shop did all the installation, fabrication, wiring, and integration of the DSP with the stock stereo. I then added an Intel Compute Stick running Linux to the DSP's digital input so that I can bypass the factory system and send music directly into the DSP from my iPhone over Wifi (Airplay).
If you're interested I can post pictures. It looks completely stock except for the subwoofer box. I insisted on putting the sub in the stock location (not in the footwell as I'm unwilling to lose any legroom) so they built a beautiful box for it to resonate into that sits between the seats.
