[QUOTE="mat3833, post: 8806840, member: 587645"] LOL, optical is basically fiber optic. Instead of transmitting the audio signal via a low voltage sine wave, the signal is transmitted as pulses of light. Obviously, you can't get electrical interference in your audio sognal when there is no electricial signal at all, so Yea it's pretty much zero induced noise. It also usually bypasses any DAC(cheaper chip) in your headunit since it's still a "digital" signal and your amp/DSP DAC(usually more expensive/better quality chip) converts it into an audio signal.
