With audio signals, a soldered crimp is one of the worst possible
connections. I wouldn't think it would be different for anything else,
but may go undetected until failure. If you've used the correct size of
crimp and used a proper crimping tool, then you've got the proper
pressure for a solid reliable connection. If you then solder, the heat
expands the crimp lessening the crimp pressure, and when it cools it's
no longer at the correct crimp pressure (often the wire will pull right
out), and with iffy wicking of solder. The worst of both methods
combined in one.
Where the wire is too thin for the crimp I have available, I've cut a
piece of a correct thickness wire/cable, inserted that into the crimp
along with the signal wire/cable, so it's crimped between them. I don't
know if that is the best way of handling that, but it's worked for me.

West Mountain is a good source for all things PowerPole, but there are a bunch
of other vendors as well. And do youself a favor -- spend $30 on the three
size 15/30/45 amp crimping tool. It saves much aggravation. But if you're
using thin wire, soldering after crimping is a good precaution.
