Best way to add terminals to 2/0 wire?

[transit360]

Yes, 2/0. I'm installing some super-high amp alternators on my
Bluebirds and it's required I put 2/0 cable on them, no 0/2, or 2
gauge. These things are capable of about 300 amps, that's why.
So what's the best way to install cable ends? Using great big
crimpers? A hammer and tool to crimp them? Could I solder them? With
what? All I want is the most secure and maintenance-free method that's
carry the load if needed. Suggestions?
