That may be a pita. My rcas are not like that but connect with a plug on the end. Ther are 3 separate but they attach with wired if you understand what I am saying.
So can I put some wire in the rca connection I am using if it does not touch the center prong and then fasten that to the chassis? If not can I solder wire around the rear set and attatch that to the chassis?
Yet another reason I am probably going to stick with alpine. I am getting a pioneer in a few days because of a trade I will install it and probably not like it or get noise and than sell it, and than get my 9887
