this is not true, why you did that??? here's that schematic
https://www.6speedonline.com/forums/...6&d=1463416883

 

I have a schematic for the PCM3 and for the AMP.

I have wired the socket like the plan says and pinned the cables at the pcm3.

But at the wiring from the PCM3 i see that front left- (B7) goes to the Amp and to Door left - and 2way loudspeaker.

The same is with Front left-, Front Right-, Front Right+.

I marked the wires at the paper and followed them in detail. - This is what i figured out.

Unfortunately i do not have a PDF Version to show you.

 

make a decision - you want an advice or to arguing? )))

I gived you link with correct wiring! I'm not interested in any pdf schematic, I have original porsche schematics program, and it's not in a pdf format.

cut that solders! and you'll get loud sound. probably. if no more mistakes.

 

Ok i will try and give feedback in a few minutes.

 

I did what you said and now there is no sound.

I tried the volume to the max, but i cannot hear anything.

Why is that, i mean with the soldered wires i had sound from the doors.

 

check rest of wiring...
when you solder old wires to new - you do straight connect speakers to pcm3. pcm3 dont have internal amp so you hear weak sound.
did you make photos I've asked?

 

Yes i made the pictures.

I made a picture of the amp with the number.

Another picture showes the black plug.

And one picture is the back of the pcm3 with the loudspeaker cables from the amp.

I checked the wiring and think it is ok.

But i also thought that wen i solder the old cables on it would be OK

 

and how can I check your wiring with this photos?

 

What do you want to see?

Please tell me, then i make the photograph.

At the amp i used Porsche/Audi Pins that i soldered on loudspeaker cables.

These cables i put through a hole into the interiour at the back of the pcm3.

At the pcm3 i took a quadlock plug and put in some pins and soldered them to the loudspeaker cables that came from the amp.

I used some tape and wrote the numbers on each wire, so that i do not make a mistake.

I can check the cables with a multimeter if they are correct, but i think there is another mistake?

 

if you want me to check your wiring I need good photos to see clearly each plug and each wire. from this photos I can only see that you use brown plug with extra wires, thats correct, but thats all...

loudspeaker cables should only go from amp to speakers ONLY!
all wiring should look like this
pcm3 b-plug extra 8 wires -> amp b-plug
amp a-plug -> speakers
constant plus 12v -> amp A1
constant earth -> amp A11
switched plus 12v from pcm3 blue plug C4 -> amp B6

no more! no extra solders. check that both pluses and earth exists on amp with multimeter.

 

Ok, i will check and report to you as soon as my car is back from the bodyshop.

 

hehe

How you doing Serg?

 

Hi, I'm allright

 

I got my car back from the bodyshop and checked the wiring.

A2 which on the old pcm2.1 is for the amp was not connected. (Instead of this i connected Wake UP Diagnosis)

I now soldered A2 to C4 and i have full sound.

But now i have no place for the old c4 wake up diagnosis or is this at the pcm 3.

Or should this pin go now to A16 at the pcm3?

One more thing is that piwis says the dashboard has no connection to the pcm3?

I ordered the usb retrofit kit and will implement it to the pcm - As much as i understand i only have to to put in the plug to the empty place right (Under the most bus?)

 

you think you playing chess maybe? e2 e4 ... ))) you cant place one wire with one schematic and next with another. why you deside that you can leave some wires disconnected?
and if you decide to make job of electrician - take time to get appropriate knowledge. what is can-bus for example
