or something of the sort of:

  sox -v 0.5 input_file output_file

Or:

  sox -v 1.5 input_file output_file

If you need limitergain:

  sox input_file output_file vol 1.5 amplitude 0.05

(Here: a limiter value of 0.05).

Sadly I have no time to check this myself, and have to take the word of
the sox man page for it.
