I suppose I could verify this myself once I get the player back in the car with the new setup but the answer will theoretically affect my wiring so I'm asking to get a heads up.

I recently had one of the digital soundboards fitted to my Rio car and the sound is amazing. I'm particularly looking forward to using the optical out in the car with my new processors and amp as it should be fairly impervious to electrical interference.

But I'm hazarding a guess here that I will need an RCA connection to get sound from the tuner?

If that's not the case, I'm, laughing, but if it is, will there be any problem connecting RCA and optical at the same time and how will the player know which output to use for MP3s if both are connected?
