Alpine HU install - question on wiring adapters

[atmorris]

I'm replacing my CDR23 (and amp) with an Alpine 9885 HU, and I'm told that some late model VW wiring harness adapters may work on a Boxster.

Anybody out there have any idea which VW models/years might be candidates to be used on a MY03 Base Boxster with a CDR23? Not finding too may off the shelf wiring adapters for Porsches at the Crutchfields or Woofersetc of the world :P

I built my own harness for my Alpine HU... Just used an ISO connector -> bare wire converter, and spliced the wires in to the Alpine -> bare wire harness that comes with the unit. That worked for the power.

For the audio signal, I retained the OEM amplifier and built an RCA lead up that I spliced in to the special Becker connector, and connected to the back of the Alpine. I believe you can actually get a proper harness from Becker, but I was impatient ;) Besides, my method allowed me to build an attenuation circuit in to the harness so that I could impedance match the input of the OEM amplifier and the new Alpine (I was experiencing an issue where I would get to number "3" on my Alpine volume control, and it would already be at max volume due to the OEM amplifier being too sensitive).

I actually put the OEM stereo back in now, but I will be ripping it all out again for a completely custom ICE setup.

Thanks!
