I've heard of a lot of people splicing their sounder cables.
Make sure you do a good solder job, and waterproof the splices thoroughly.
If, upon dissection, you find that the cable is shielded, you can wrap some foil around the insulated splices, making sure it shorts to the shields on both sides, and shrink tube the mess together. You may get the sounder signals leaking over to your VHF otherwise (sounds like annoying little ticks.)
