does your amp have a dedicated (amplified) set of speaker connections labelled for a sub?
you sub needs connecting to an amplified source just like a regular speaker via the regular speaker type spring clip terminals.
if your amp has a subwoofer line out socket (which i'm guessing it has looking at that pic) you can easily conect an active sub using the line out connection.
but you will need an active sub. ie one with an internal amplifier
