When you removed the old stock radio, did you cut the wires to accommodate the after market system. I assume you did?
If you have the old radio, and the original plug to verify the color codes of the wires, then you can trace the speaker wires. There is power (red), ground (brown), and then 8 wires the the speakers. 4 front, and 4 rear, left and right side.
The connections are grouped to right and left. If you make a mistake, it is easy to correct.
Use the original speaker wires to confirm. It may mean pulling off the door panes to confirm.
Getting back to your question, go to the amp first, and then to the speakers.
Hope that helps?
