I am in the middle of replacing my old Pioneer deck with a new one but when I took the old one out I didn't pay attention to the speaker set up.

I have 8 wires but have no idea how what is for what. I can't take the door off because I need a certain hex tool that I don't have right now.

The wires I have are grouped in 4 groups, 2 wires per group.
Grey w/ Black stripe
White w/ black stripe

Grey w/ Red stripe
White w/ Red stripe

White w/ Purple stripe
Grey w/ white stripe

White
Grey

Any help would be greatly appreciated
