I was told by someone that all connections are likely still via harness? Have they not figured out how to put a line-out on these things yet? I just test drove a '14 coupe (w/ Navi) and all seemed great but that bass response seriously needed help.

Has anyone cracked one of these open yet? How difficult would it be to add/augment on top of the stock system?

Thanks in advance,
Matt
