Soldering a crimp is not good practice, a correctly done crimp will not come loose (OEM connections are mostly crimped), and you risk making a brittle section if the solder wicks past the crimp.
A correctly done crimp uses enough force to form a cold weld. Unfortunately, without a calibrated machine to do it, it is pretty hard to determine if enough crimping force has been applied. Without the cold weld, corrosion will compromise the joint after a year or so. The solder will also prevent moisture from getting into the joint.
You're right about not letting the solder wick up past the connector. But that's not an issue if the wire is properly supported with a clamp.
My experience with crimps is electrical gremlins, with soldered crimps, no trouble at all.
OEM crimps also come with a molded housing designed to keep out moisture (and corrosion) and provide mechanical support for the joint. The crimp-on connectors at the auto parts store are vastly inferior.
That's called a crimping tool. They grow on trees. They're designed to achieve the correct amount of force to make a gas tight, permanent connection without destroying the contacts. All you need to do is select the correct connectors for the wire size you're dealing with and squeeze it.
