Hi,

I've decided to upgrade my M490 to M680 and add rear speakers. I've bought the following from eBay:

1. M680 DSP amp (part # 986.645.312.00)

2. DSP control unit (part # 996.645.201.02)

3. OEM rear speakers installed in the "box"

After bringing it to CarToys, their installer said that I need the wiring harnesses to connect the amp, control unit, and speakers. What parts should I order from Porsche? My car is 2000 Boxster with M490, CDR-220, dash and door speakers.

I called my local Porsche dealer and they were not helpful.

Please help and thanks,

Iwan
