So I know there are lots of options and previous threads out there but need to make a decision and would like some up to date information. 2021 LC. What’s the consensus on best unit available right now from people that are actually using them?? Hamilton? Grom? Is it something I can YouTube and install myself or better left to audio pros?? Does not look terrible to install from what I have seen so far. Really want to stay as close to factory as I can. Anyway….whats the group’s thoughts?? Thanks in advance
