installing subwoofer to 2 channel system


I want to install a subwoofer to a 2 channel system.
How do I hookup a subwoofer? Do I need a home theater pre-processor or Do I use a 3 channel amp and hook 1 to the sub. I am a beginner here.

Depends on the sub. A suitable powered sub would have connections to take care of the interfacing with a regular stereo system.
