In a residential application 2AL is good for 100 amps. Any other application, 2AL is rated for 90 amps, so you have 180 amps available in theory. That being said, I don't think the code allows parallel conductors that small, because a larger conductor is available.
250 kcmil AL will handle 200 amps with one conductor.
