2013 Shaker 1000 Sub

[Randylueders]

I just got a shaker 1000 sub I wana put into my 2013 GT. Going to run a after market amp to it seeing how I only have the shaker 500 system in my car but don't know how to hook my subs up to my amp cause of the four wires coming out of the subs. No clue which one is ground or power the wires are the same colour.
