Crimp, Solder, Crush
For a future project, I need to terminate 2ga, 4ga and 6ga wire. I already have most of the wire and a few bare copper lugs for this size wire but am looking for the best way to mate these two togethe...

I made at least dozens (maybe more than 100)of connections using 2g wire. I use a hammer and chisel on concrete to crimp -- strong as any possible crimp. I then solder to make absolutely sure of the best electrical connection.
Zero failures. Cheap and reliable.
I do something pretty similar. I have a larger than average bench vise, so anything larger than 12ga I put in my bench vise and squeeze it down, then solder with a 400 watt gun.
If it's really large, as with my 3kw inverter, I used 0/4 and crimped in the vise, but then had to use a 1500watt radiator soldering iron. I also use a butane torch to solder the really big stuff, just depends on the application.
