Installing a radio kit with a floating head radio

  • hi everyone. I want to add a floating head radio in my 2017 slingshot sl and need some clarification. I’m looking at buying the aluminum double din installation kit from sling mods but I’m confused on the wiring. If i buy the scoche wiring harness kit with backup camera integration then how do i wire up the speakers? I see only power,ground and acc wires plus the camera wiring. Any help appreciated
