lol where do u think that power comes from?a capcel is like a battery bro. When I sell my setup im going to be running an 18" Fi BTL with a saz-3000d. I'll be getting two C&D Tech batteries, pretty much the same as the kinetik 2400's. I just want the cap cause its cheap and will keep some power off my alt. I don't want to buy a new alt for $500
