Hey Russell. I’m not sure if I can find an identical speaker to the one in the lifejacket, but I wonder one with the same measurements would be a suitable replacement. You’ll have to measure the speaker yourself (as I don’t own one), but [https://www.banggood.com/1pc-40mm-4-3W-Full-range-Audio-Speaker-Stereo-Woofer-Loudspeaker-p-978610.html?rmmds=buy&cur_warehouse=CN|this one] is 40mm diameter, 20mm height, which seems in the ballpark. As far as the wires go, I would try to resolder the original ones rather than find a replacement for them given that white plastic harness they’re attached to.
