Wiring for tower speakers on 2017 243 VRX

[OldForgeVRX]

the wiring for the tower speakers came pre-wired in the tower however the two purple and two green wires have a connector attached but are just stuck up behind the side panel on the port side. How do you attach the prewired connector to the sound system in the boat?

I’ve only worked on my own boat (Yamaha) but speaker wiring is pretty universal. Without seeing what you’re seeing, I would suggest splicing speaker wire from the wires you have to an amp (which I’m thinking you don’t have or isn’t big enough seeing you said “to the sound system in the boat”) and from the amp to available RCA off the back of the head unit. My boat had 2 available RCA (F&R).
