Tutorial for Installing Stereo into Volvo 940 (wiring guides included) 900 1994

With all due respect, I never solder electrical connections. Proper crimp connections carry power much better. I never have have crimped connections pull out or corrode, and I've made many thousands, probably many tens of thousands in over thirty years.

The starter and alternator on your car have crimped connections on the cables which connect to them. The factory wiring on your car uses only crimp connections. That should be good enough for a radio. The only factory soldering on your car is connecting to circuit boards, and alternator brushes. The electrical construction industry uses crimp connections. There are a few military spec crimps, on aircraft, that have the crimp fittings filled with solder to avoid the potential of corrosion in hostile environments. Those crimp fittings are terminated under setscrews (pressure) fittings and there is no solder there.

Nuclear plants, power plants, and semiconductor fabs use crimped or setscrew terminations. If solder was better and more reliable, those industries would solder their electrical terminations.

I don't want to start a war, but crimp and setscrew (all are pressure connections) terminations are better.
