I got an Alpine CDA-9813 as a gift...part of the "gift" was having it installed at Circuit City of all places. Anyways, I was reading through some of the book, and read on the internet somewhere, that the head unit needs to be fused directly to the battery. When CC installed it they simply hooked up the wiring harness and antenna wire and called it an "install"...no direct fuse to the battery. My question is, will I be getting the full 60 x 4 rating without having it fused? Is the V-Drive even being used?
