I have just hooked up a brand new Alpine MRA-F350 amp to my Alpine IVA-D310E head unit with all the correct fibre optic cables etc...and now find i have no sound from the AM or FM radio side of things. The CD and DVD players work fine and the radio was working fine with the pioneer amp i had in the car previously but for some reason the radio will store all the correct stations on manual tune or A-Memory but no sound will come through?Any ideas? Cheers Brenton.
Neither of those units use fibre optic cables! but it sounds like you puled out the antenna wire behind the head unit. if you try and search radio stations without the manual tune on and it keeps changing frequency on it and never stops then its the antenna plug.

The amp requires a compatible Ai-net Alpine head unit to operate it. I bought one too and didnt know this and im still trying to put all of the peices together to create a working stereo system without buying everything all over again.
Sorry man here's what i pulled from the internet- Crutchfield sells these: Note: The MRA-D550 requires a compatible head unit for
setup and control, it cannot be used without one. The current list of
compatible head units includes (but is not limited to): IVA-D300,
IVA-D310, IVA-D900, IVA-D901, DVA-9860, and DVA-9965.
Check Your voltage coming in AT your 12volt power wire and them check voltage on your Power Remote wire and make sure you have both of them..... Next Check your RCA's For signals. IF all that is checked out to be good then you have a bad board in your amp.
