I traced the lack of signal in my rear port speaker (next to the companion bench seat by the helm) to the speaker wire, so I pulled out the radio in the cabin and was all set to pull new speaker wire through using the old speaker wire from the speaker side. However, after I unbundled the old speaker wire from all the twists and ties and tape behind the radio all the way to where I could reach until the wires disappeared into the starboard side to start the run forward around the bow, I can't pull the wire through and it still doesn't budge. I suspect the wire is tied up somewhere further along the run, and that this was done at the factory while everything was nice and exposed. Does anyone have any ideas how to free up the wire to pull it through (I can't see access points along the run and it could be tied up anywhere along the run or in numerous places, or else to suggest an alternative speaker wire run from that speaker to the radio? TIA
