Before you say anything i know that somewhere on this site has got be the correct forum but i have searched and searched and i can't find it, can somebody please direct me to the correct area, don't wanna get fussed at for reposting..haha. Anyway i bought a Boss Bv9560b head unit (in dash double din HU) and have done many HU installs over the years but never on a mustang. I was reading up on some how-to's and all i see is, "you have to replace the factory amps" "you need a voltage regulator" " you have to re-run the speaker wires" all of which has got me nervous about the install. I currently have a 2004 GT with the Mach 460 6-disk. Any help would be wonderful thanks
