In the process of installing the pro kit and I've been having major issues. The audio sounds very "faint"- there is really no better way to describe it, but the quality is definitely not CD audio quality. I do think it is mostly because the ribbon cables are not straight- I have not found a way to install the board without twisting it in some way to connect both the ribbon cables as well as the RCA input from the provided GLI. any advice in terms of how you went about installing this? Details from the manual are vague and it appears the board i have is different than the one mentioned in the manual. thanks!
