I am looking to buy a pair of 12 inch Kicker C12vr 's. But how does dual voice coil work. How do i hook it up to my amp (RF 800.2)? Thanks. Bobby.

 

It's tough to explain all the possibilities that a dual voice coil (DVC) woofer opens up. JL Audio's site, however, has a pretty sweet tutorial on the subject, though. I know it's not RF, but the concepts are exactly the same. The site explains it a lot better than I could and they have a bunch of pictures as well. Just go to this link:

Their page also has easy-to-understand wiring diagrams that you can download.
