I got a whole bunch of Belden RG-6U cable from the local cable company and used some of it for a pre-amp link between two stereo systems that will be in my new house. I also used this same cable for a pre-amp to the sub. I can't find a Belden part number on the cable. It was probably made for the cable company since it has its name on it. I know this probably isn't the Belden's RG6 that most people on this site recommend for pre-amp signals, but will I really notice a huge difference. I'm mostly concerned about the sub's pre-amp. If I would have had more time I would have gotten the right cable. Thanks for any feedback.
