Hello everyone, I have a question that i cant seem to answer using the power of the search button or i may be not understanding this correctly. I was at Circuit City and noticed how they had their subwoofers hooked up. They used coaxial (RF) cable with adapters on the end to make a RCA plug. Is this where the RG6 cable can be used??? Can this be done or is the cheap way, meaning loss in quality of signal??? Can i do this in my home??? My subwoofer is the velodyne CHT-12 conneted to a Denon 3803. Are there any y-adapters so that i can run one cable and then branch to the two inputs on the sub?? I was told this helps.....Does it??? Thanks for the help. Nik K.
