Default 2001 A6 C5 Stereo Install Issues

Im sure that I pulled a nub moved and over-looked something. But I purchased a Sony XAV-63 with the correct Metra 70-1787 wiring harness.
The factory setup is the Symphony Cassette - Single CD with Bose integration.

From what the directions on the wiring harness state, if the system is powered by bose then only utilize the RCA connectors. Upon doing so - the Sony radio has 4 outputs for front and rear audio.

Im only getting sound from the front left speaker and the sub. Anyone have any ideas on what I might be missing?

Thanks!

How many of the RCAs did you plug in?

Also, does the regular plug (is your adapter) have the speaker wires still plugged in?
You may have a conflict...

All 4 as stated on the instructions listed in the package. I move the rears to the front and the front to the rear. Whatever location that one RCA was plugged into, no audio..
I got a replacement from Amazon and waiting to install the new harness, to determine if the old one was bad. Which it seems to have just been an faulty RCA plug.
Also I waiting for my 4 channel ground loop isolator to install.
Hopefully the new harness works.. Ill post some pics of the install once its all done.

So I got the new wiring harness in - got everything wired up correctly. Plugged in the 4 RCA's for the front and rear speakers. Again.. All speakers work execpt for the front driver side speakers.
I moved the plugs around and tested to see if the channel from the radio is broken and it is not.
It seems to really not like the one channel from the Metra Wiring harness. Where ever that is plugged in - no sound.

Im baffled at this point.. This is a new harness from Amazon (2nd one / replacement) I have the ground loop adapter setup and its working just fine.
Yes i have the setting for the RCA's on the head unit to Rear and not Sub.
Anyone have any ideas?

Just to be clear:

1) You get sound on 3 of the 4 speaker positions?
2) You can get sound from all 4 speakers, but only 3 at a time by shuffling the cable connections?
3) Your original Audi Symphony radio displayed "BOSE" at startup?
4) With your original Audi Symphony radio connected all 4 speakers work as expected?

I've not looked at this stuff in a LONG time, but I thought I remembered non-Bose cars had a rear amp only with fronts driven directly by the head unit, and Bose cars had a 4-channel amp but used a little 2"(?) speaker in the driver's side B-pillar for phone and Nav which is driven off the Front-Left speaker connection. It seems an odd coincidence that your Front-Left speaker doesn't put out audio. Have you checked the Nav Mute and Phone Mute connections on your harness? I don't recall if either feeds into the Bose amp, but if they did that could explain it - if the Bose amp thinks the Nav/Phone is in use it could be muting the driver's side channel to allow the B-pillar speaker to be heard....

Packed everything up and getting ready to return it all... Not sure what could be missing as everying from the Metra harness is plug and play. No matter what order I have the RCA's connected, theres no sound from one speaker... UGH.

No such thing as plug-and-play, only plug-and-pray. Check the harness - visually at the least. There's a sticker on the Symphony if you're not sure which connections are which....

At the moment I suspect one of your mute connections is grounded and disconnecting it may solve your problem, but I need you to answer the #'d questions above to be sure we're saying the same things....

- Nope Sorry for the confusion. No matter the order there is always one speaker with no sound.
3) Your original Audi Symphony radio displayed "BOSE" at startup?
- Yup
4) With your original Audi Symphony radio connected all 4 speakers work as expected?
- That was my first test as I thought I had blown a channel. Hooked up the original Symphony radio and tested all speakers. Yes all speakers work with the Original factory radio installed.

Very true.. At this point i want to set it all on fire.. lol
Anyways I checked the harness again all connections seem solid. There is one harness that is not plugged in which is the block for Navi/Phone etc. My A6 does not have Navi or the phone installed. Also the metra harness does not have a female block for the factory harness to be utilized.

Maybe I'm confused by the late hour .... I think we're saying the same thing:
-when wired "correctly" you get sound from RF, RR, LR speakers, but not LF.
-when you shuffle the connectors, you can get LF sound, but then some other speaker is off

Have you looked at the Symphony sticker and compared the connected pins?
Click the image to open in full size.
That's from RNS-D Nav+ but Symphony is similar - though I don't seem to have it online, it had a NAV mute and a Phone mute. What was connected to those mute inputs before and what's connected now?

What happens when you disconnect whatever dangling connectors from your Symphony? That is, hook up the Symphony with the same connectors as the Metra uses - leaving the Nav/Phone/whatever one dangling. If we can prove the dangling connector causes the problem we can figure out why.

The dangling connector that is not being used, would be the plug for the nav, phone - mute etc. The metra harness does not have a section for the plug. The 3 plugs outlined in yellow are the ones being used.
Here's an image of what factory plugs are being utilized.

Is anything connected to the MUTE pin from the upper right corner of your circled yellow box? How about the K pin from the same connector?

Since the speaker-out connection should be unused, try disconnecting that one for grins (large 8 pin connector with the 2 speaker icons in the middle row of your circled yellow box).

I'd also try running the Symphony with the right hand uncircled vertical 3 part connector for NAV, PHONE, etc disconnected.

I suspect something is confusing the Bose amp and making it think it should mute the driver's speaker. I suspect that's because it's seeing a MUTE signal when it shouldn't. IIRC, those are ground-to-MUTE pins, so floating them should be the right answer but a little experimentation (as above) might give us a better idea.

Yup there is a harness connected to the MUTE pin from the upper right corner of the pic (circled in yellow) But not 100% sure if there is anything connected to it from the metra harness.

Ill try running the symphony with the connector for the nav, phone etc disconnected and see what happens..

Thanks a ton for your assistance!!

There is nothing that is connected to the MUTE pin from the metra harness. Also I tried to run with out the brown plug attached for the lf and rf speakers as shown in the middle connector that is circled in yellow. Still nothing. Ill try to see what happens when i try to run with the Nav/Phone plug removed from the Symphony radio.

Read this post on AudiZine.
Re: Pioneer AVH-P4000DVD with Metra Wiring Kit Difficulties... No sound...
I gave up and brought it to best buy... it took that guy about 5 minutes to figure out that Metra had put the wires (talking about red amp harness here) on the wrong side of the harness..... so I paid him for that and now it works good! Funny thing is that I ordered the metra harness for bose systems... stupid metra!

http://www.audizine.com/forum/showth...lties-No-sound

I never verified that the wires from the metra match up with the left front channel.
Another task list item to check.
Ill report back soon.

Offically out of ideas.. Still the same issue with the new harness. Verified that the pin layout for for the RCA connections are correct per the sticker on the Symphony radio...

Crap, I'm stumped too I was so sure it was the muting line somehow but I just went and looked through the schematics and I'm not sure it even goes to the Bose amp, so I may have been way off from the beginning.

Have you ever tried it without the ground loop eliminator?

I'm grasping at straws

Actually, the ONLY thing I see going between the head unit and the Bose amp is that 6-pin connector with RF, RR, switch, COM, LF, LR.

COM would be COMmon or Ground, RF/RR are the Right Front and Rear channels, LF/LR the Left Front and Rear.

The little switch symbol is most likely the remote power switch for the Bose amp.... to what is that connected on the Metra?

Seems like it would either be tied to power or ground - at a guess, to ground - floating might be bad. If it's not connected, hook up the Symphony and measure that pin with your voltmeter to see what happens when you turn the radio on and off....
