2018 Sound System Upgrade

Good to know. Thanks.

This all for the B&O system in the 2018's?

yes. there is no pac interface for the 2018 yet. and every other vehicle i have done higher end audio systems in were also the same. after the oem amp.

OP updated with amp wiring diagram, still can’t figure out where the tweeters are hooked to though, don’t know why they wouldn’t be connected to the amp.

_____UPDATE___
Based on the diagrams I just posted it looks like the tweeters are NOT wired through the rear amp, looks like they connect directly to the "audio Front Control Module".

OP updated, everything is working, wiring diagram is attached, tweeters do NOT have a signal output from factory amp. Tweeter signal needs to be taken at the tweeters themselves, see updated OP for details on how I did this. Hope this helps someone out.

Here are the pics of the install, everything is sounding pretty nice. Might get Noah out sometime to do a professional tune job but so far I’m happy with the results.

Did all those amps fit behind the seat?

Everything fit no problem, the one JL speaker grill gets pushed on by the seat a bit, that’s the only tight fit.

just be careful with people sitting in the rear seats. the grills will get damaged and possibly cave in which will make the woofers hit it and cause damage to the speakers.
