How Would I Be Able To Get The Most Power Out Of My Amp?

Here's my problem, seems like the amp that I bought isn't powerful enough to power my 2 12" RF subs, but seems to work pretty good with one sub, its plenty power for me with one sub. Here's the info of the amp below and and below that, will be the info on the subs. How would I be able to power my one sub as much as possible with the amp, how would I connect to the speaker the amplifer terminals? Is this even possible? Thanks, I would really appreciate it!

If your subs can be bridged at 2 ohm you should be ok with that amp.
