No sound from speakers after mra-f350 connected to alpine w205
I just connected the alpine mra-f350 to my W205 head unit via the AI Net cable, then connected the power and speaker leads to the amp. The amp powers up, but no sound will come out. Tried to see if something had to be turned on / set on the head unit by going through the source menus, but nothing worked. any idea what the problem could be?

On the ai net cable identify and separate strand with green, blue and unshielded common/ground. G and B will be your positive which you will then solder to red and white leads from rca or headphone cable with unshielded from that cable twisted together and soldered together with the unshielded wire from ai net cable. Tape off or heat shrink the rest of wires from ai net cable.
One thing to verify is that the Ai-Net switch at the bottom of the radio is set to Norm and not the EQ position. And also gray Ai-Net connectors are for audio input and the black Ai-Net connectors are for audio output. It sounds like you have everything connected correctly and at least the Sirius is coming up. And I assume that the CD changer works when connected directly to the reciever so you know that it is working. I would suspect that there might be a problem with the Sirius reciever not allowing the communication signal to connect to the Alpine deck and in that case you would need to get a new reciever. You could check the Alpine radio settings and see if there is something that needs to be changed in order to allow the CD changer to work. If you disconnected the battery connection to the radio then it might have reset the settings to factory default. Otherwise it sounds to me like the problem is with the Sirius reciever.
i would suggest alpines new 5 channel suround amplifier that has dolby 5.1 decoding and you will also have to have a head unit that supports 5.1 surround sound which as far as i could tell are only indash dvd players you will also need to purchase a center channel speaker as well
you can follow this link to the alpine amp http://www.crutchfield.com/p_500MRAF350/Alpine-MRA-F350.html?tp=115
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.
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.
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.
It is possible that the SIR unit stays powered as long as the red wire is powered, since it is normally connected to a switched source. To test this, disconnect the red wire or move it to a switched source (you could even add a switch on the wire and flip it manually).
If the battery stays healthy after that, then the red wire being constantly powered is the problem. Otherwise, it is possible there is a problem with the Ai-NET cable connected to the SIR unit.
