[66pamustang]

Hello, i am new at this so i will apoligize up front. I own a 1966 mustang and am having some electrical trouble. I just bought a replacement AM/FM radio and replacement parts for the horn. While I have power at the radio i am getting no sound and it will not flip between radio, ipod setting and cd settings. All the horn connectionsd were made correctly including the atenna and speakers. The horn has spark but will not sound. Is this an electrical problem or other?
