Great DIY! I'm about to start this project. I am planning to use some premium audio cable with a 12mm x 6mm thick cable body. Given the size of the jack that was routed and fished, I don't anticipate this will be a problem.
ZZen330, can you comment on which steps are not necessary? Thanks.I did something similar but you could have saved some time and work on a few of your cable running steps that were unnecessary.
