Ok, I'm tired of these guys hooking up a linear to the fuse panel and then wondering why it doesn't work right. A linear or even a radio with a built in linear, RUN THE WIRING DIRECTLY TO THE BATTERY! A external or internal linear aren't any different. No ifs,ands, or buts about it. DO NOT run it to the fuse panel. If you do, you're gonna smoke your electrical system and smoke your radio setup.
