I would say try to get the tube connectors, that connect 2 wires end to end, with no seam. it is hard to find the ring connectors with no seam so try to find some with what looks like a fused seam, they will be less likely to spread apart at the seam when crimping, taker a look at the crimp when done and tug the wire to ensure the crimp is gonna hold before shrink tubing it.
honestly, I am not a fan of fusible link wire when you can get a fusible link in a plug and play scenario. just me though.
check out automotive sound sites ot go to the nearest high end car audio shop and ask what they have. these would possibly be a better choice that a wire style. easy to see and replace.
