03 Box base amplifier wiring color code

[tolum]

Hi, I'll be wiring my new amp. (repace the oem) this week. My amplifier will be in front trunk. I would like to use speakers wiring that goes to the actual oem amplifier plug to route them to my new amplifier. That will save lot's of wiring time.

Any body know the colors code wires VS speakers? Are the one color wires positive or negative VS the two colors wires?

Thanks for your help.

I don't know if it's exactly the same for your 2003 Base Boxster, but here is the wiring from a 2001 S:

(I got this info from another board member, but forgot who it was)

Striped wires are negative.

Right dash speaker

Red = positive

Red and brown = negative

Left dash speaker

Yellow = positive

Yellow and brown = negative

Sub door speaker (I think this is the right side but might have this reversed)

Brown = positive

Brown and Green = Negative

Left door sub (again might have this reversed with the right)

Purple = positive

Purple / brown = negative

solid brown is the ground (don't need this but could use this if you wanted to ground the new amp)

Blue is the switch wire
