I did a search on "Should I solder car audio connections?" I reviewed a number of posts on several forums. Most of the posts indicated that crimping with a high-quality crimp tool was a good method. There were some posts advocating for solder. The only caution I saw about soldering was a warning about putting too much heat near a factory connection that was soldered.

I note that the OEM woofers have a spot of solder connected the wires from the voice coil to the terminals:


For what it's worth, I've also seen technicians on auto restoration shows such as Wheeler Dealers use soldered connections including Ant Anstead soldering connections after he swapped an alternator in to replace the generator on a TR4.

I am concerned that a soldered wire is more brittle and could crack. I'll research more thoroughly before my next project.
