Answer

If you think that yellow and red go to the same location, I semi-doubt that you know speaker wires much better (esp since you have one of the speaker wires left over), but since you asked about that Pioneer, here we go:

Yellow (memory)
To terminal always supplied with 12v power regardless of ignition switch position.

Red (Power)
To electric terminal controlled by ignition switch (12 V DC)
ON/OFF.

Black (ground)
To vehicle (metal) body.

Blue/white (Remote turn-on lead or 'Kicker lead')
To system control terminal of the power amp or Auto-antenna relay control terminal (max. 300 mA 12 V DC).



Gray and Gray/Black
Front Right speaker positive and NEGATIVE leads.

White and White/Black
Front Left speaker positive and NEGATIVE leads.

Violet and Violet/Black
Rear Right speaker positive and NEGATIVE leads.

Green and Green/Black
Rear Left speaker positive and NEGATIVE leads.

mmmk?
