My 2016 2350RSFB had a sport arch with blanking plates over the speaker cut outs so I thought I might add a couple of speakers to get some audio at head height while riding. Behind the blanking plates I found speaker wires and LED wires pre-wired. Installed some Kicker LED speakers and low and behold no audio. Went digging under the helm and found the speaker wires laying there unconnected. After doing some investigation to see how my other speakers were wired to my Kicker MX800.5, I found that my starboard center speaker (I currently have front, center (near the helm) and rear deck speakers) looks like it might be run in series with my front speakers. Both my center and front speakers use gray and gray/black wires and it looks like one of my center speaker wires comes into the harness and goes back out another piece of wire loom, potentially to my front speaker. I would have expected both speakers to be wired to my amp in parallel under the helm. Could they be in series?? If so, can I connect my third set of sport arch speakers to those channels in parallel or do they need to be wired to the rear deck speaker channel?
