Replaced PCM1 with aftermarket head unit - no sound

[EVOeng]

Hi All,

 

I'm in need of some help before the car goes off to a car audio specialist. I've run a search on this forum and others but I've been unable to find the answer.

I have a 1998 996 Carrera with the 10 speaker system and factory amplifier.

I have installed a GT3 centre console delete and as such, I have had to relocate the climate control system to the upper dash.

I've also had to remove the PCM1 system and replace the horseshoe surround to support a single DIN head unit.

 

With the PCM1 removed, I'm left with four connectors. Two of which (wider blue and black connectors) are not needed as far as I know.

 

 

The multicoloured connector and the black small connector fit into the adaptor I bought. I've seen others use the same adaptor.

 

This then connects to the harness that came with the new head unit. Once the 4 RCAs are connected, I've then attached the blue remote wire to the remote signal wire from the head unit. 

 

The head unit powers up as normal but I get no sound. 

 

Can anybody help?

The blue and white wire in your adapter harness needs to go to an ignition switched supply. It is the wake-up signal for the amplifier.

Hi Richard,

 

I've tried that but I still get no sound.

It's going into the workshop in a few weeks.
