290 Sundancer Running Speaker Wire to the Radar Arch

[Herrickjde]

I want install speakers on my radar arch and it looks like on my 1998 290 there is no hole to fish the wire where the arch connects to the body of the boat. I want to know how any of you have run the wire without drilling holes below the arch. I put a video snake camera in there and there is only one tiny opening for the cockpit and nav lights and antenna coax. looks like that was installed when manufactured. See my drawing and that is where I am having an issue.

I have a 1995 290 and had the same "tiny" hole in the same location. I managed to snake both a cable for radar to the arch and coax from a new VHF antenna back down through the same hole. It took a LOT of effort-even with lubing the cables-to get them through alongside the factory navy and arch light wiring, but they did make it.

I'm not sure if this helps you at all but I would think there has to be a way to get speaker wires through yours.
