Sorry if this was posted before and I missed it. I've got an '01 Ultra classic and have a problem with the front speakers. The morning after I got back from the Lima flat track race my front speakers were dead when I started the bike. Tghe rear work fine and I can tell a difference in the rear when I adjust the fader button. Does anyone know if there's a fuse inside the radio,before I try taking it out, or have any ideas?
