Question about Alpine MRA-F350 Car Audio Amplifier

1 Answer

No radio sound from my IVA-D310E

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.

    Both these units DO use Fibre optics as its the only way you can hook up the MRA-F350 to the head unit,there is no provision for RCA's or speaker wire inputs what so ever on this amp.Also the arial cable input is on the brain unit not the head unit so that counts that one out as well !You probably need to study these units a bit more first before offering info!

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 about that i read over those model #s real fast. thought it said MRP-F350 and that h/u is a european model. anyway the antenna wire thats plugged in to you brain is most likely an extension from its original location behind the h/u, on most vehicles anyway. you may want to check that as it may have worked its way out. you may also want to take a closer look at that brain im not sure on that model but on some alpine units there are multiple ant. inputs on them one is for am/fm and one is for sirrius radio you might want to check that as well. hopefully this helps.

What do i have do by to make my alpine iva-d310 work insted of being blank


It Depends On What Is Wrong In The First Place... (Note) Make Sure Your Radio Is Hooked Up Correctly! All The Wires Have To Be In The Correct Places for the radio To Function Properly, Its Probably Color Coated So Just Match Wire to Wire From The Radio To The Harness, If U Dont Have a Wire Harness That Matches ur Vehicles Model Or Harness Then U Will Have to Go And Purchase One At Wal Mart Or Best-buy,If U Already Have The Proper Set up And Ur Radio Is Hooked Up Correctly And Its Still Not Working. If U Can Here Sound But No Picture then It Is Most Likely Your Lcd Ribbon That Connects From The Main Unit To The Flip-Out tv Screen, Hope This Helps :-)

Comes up with disc error


cd cleaners usually cause more damage than good by scratching the eye that reads the cd. my recommendation is to try and find where your local alpine repair place is and bring it there.

Volume will not go passed 4


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.

Hooking the mra-f350 to my highs


You will only need to connect the door speakers to the MRA-F350. In short, the connections will be as follows:

Deck---->MRA-F350 amp---->Door speakers
...................................\---->Sub amp---->Sub(s)

Just make sure you use the optical digital output of the deck to connect to the optical digital input of the MRA-F350 amp, not the RCA preamp connections.

No sound from speakers after mra-f350 connected to alpine w205


Did you set the digital output to the on position on the bottom of the head unit?

You have to switch the head unit off then back on for it to recognize the position of the switch.

Alpine mra-d-550 car audio amplifier


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.

No sound from turn by turn navigation


I have an MRA-F350 decoder/amp, which needs a KCE-900E between the Nav and the Head to correctly route the audio.  Without it, you'll only hear directions when you're specifically tuned to the Nav input.

I looked at the manual for your processor, and it looks like it needs the same thing (pg 42 in PDF on Alpine's site)

Nav  >  KCE-900E  >  Head  (RGB)
KCE-900E  >  Processor  (RCA + Guide Control)
