2004 grand prix speaker wiring

I'm trying to install an amp and 12" subs in my 04 Grand Prix GT and I'm not sure if the wires behind the radio are the same color as at the rear speakers. I bought an inline converter which comes with 6 wires (2 should go to the left speaker and 2 should go to the right, the other 2 may be ground or something, not a big deal). The rear left speaker at the speaker itself is brownish-purple and yellow. The rear right is light blue and dark blue. Are they the same color at the radio harness? And where does the remote wire to the amp get spliced into behind the radio? Any help would be appreciated.

Someone posted the wiring info for your 04 Grand Prix already. Have a look here.Installer, IT support, and FFL. I need less hobbies.

haha yea thanks I ended up locating that page about 5 minutes after i posted the question.
