I just posted this question about the front speakers but I found the wiring diagram for a 2001 Boxster with the M490 option and jotted this down:

Right door speaker: + Green
- Green/Brown

Left door speaker: + Green
- Green/Brown

Front left dash speaker: + Yellow
- Yellow/Brown

Front right dash speaker: + Red
- Red/Brown

Sounds like your colors are diff but if the above is any indicator the negative is the wire with the contrasting stripe.
