2000 LC100... I'm interested in audio upgrade options. I searched forums and couldn't find anything about retrofitting the Levinson audio system in a 2000 LC. I don't know if it's even possible to purchase let alone install TBH. I'm trying to keep this build OEM+ in terms of aesthetic and functionality and would consider aftermarket if it looks mostly factory. Just not sure where to start, would love some input from those of you who have done audio upgrades.
