I have a 2018 gx460 with out Mark Levinson but with navigation. Sound system is not that great. Has anyone had any experience with the system offered by
OEM Audio+? It looks like a very nice system, wonder how the subwoofer is mounted and where.

Any insight would be appreciated, Thanks

No, but it looks awesome. Plug-n-play would be a huge selling point for me.
