can someone provide a wiring diagram showing power ground, remote turn on and rca signal from the oem wiring. I am installing a new amp and want to keep wire harness intact. I have the speaker wiring down just need the other wiring color codes to tap into them to wire into the new amp.

 

Year, system, MOST? Need more info to be precise.

 

At least show us the old amp/model sticker.

The Bentley manual has for schematics for these cars if u want your own paper copy.

 

Isn't the MOST system a fiber optic system? My car is a 2001. This is not fiber or BOSE. Becker head unit. My car does have the Jenhert Audio upgrade which is a rare feature. (upgraded amp dual speakers on doors)

Amplifier is model number 9906 Type: ATP 400x

I want to be able to use the power from the larger-off white harness and the antenna remote turn on but I am not sure where this is located on the two harnesses (large white/small black)

 

Is there an online version available like the PET?

 

The ATP 400x and M490 amps were used in cars with the 'Hi Fi' audio package (option code 490).





I don't know if these will help but I saved them from several years ago when I was trying to troubleshoot something.

 

Would you happen to know what the remote turn on is from the two plugs that goes to the amplifier? I'm assuming the smaller black plug at the amplifier is the input from the the stereo and the wire colors are the same. The schematic provided I am not sure how to read.

I was trying to prevent having to run a remote wire and rca wire from behind the stereo to the frunk area.

 

It should be the black with red stripe wire labeled "12V+" on the amplifier, coming from "switched" on the Radio.

 

I was looking for the wiring from the OEM wire from the front to the Frunk that could be tapped into. Mainly the remote turn on wire. I believe it is on the smaller black connector going into the amplifier, but I am not sure which wire to tap into.

I think for safety reasons, its best to use the amplifier ground and power. I just want the remote turn on at this point.

 

Right, that's what I said. It's swtiched 12v from the radio... that's the remote turn on wire.
