Rzr XP1k ssv works behind seat sub wiring

I recently order a unloaded ssv works behind seat sub for my rzr 1k. well it didn’t not come unloaded, it came with the ssv works sub and amp that plugs in to the ssv works over head stereo. but I don’t have a ssv works over head stereo I have a custom fiber glassed over head stereo that I made and is controlled by wet sounds blue tooth controller.

iam curous on how it would sound set up the way it is now instead of putting my Rockford fosgate p3 sub in powered by a Rockford 500w x 1 amp. there are 6 wires coming out of the amp 2 for main power and ground for the amp and then 4 wires on a separate plug. so my question is are the 4 wires (blue, red, white, and black) just a hi level input setup and which wires are which?
