Honestly, I am an online G30 junkie who is all over forums and Facebook groups. Many have asked this question and I know no one who pulled the trigger on procuring all the hardware. Coding is not the issue, that is the easy part. Cost and level of effort is just way over the top. Just put it on your list for the next car. I know no one who has retrofitted it for good reasons. It's not just speakers, subs and an amp. You are looking at a new wiring harness that needs to go to EVERY speaker point as well as the amp.
