will this power a 50 watt bass shaker?

And by the way..saying "50 watt bass shaker" does not describe or define the bass shaker. 50 watts is merely the recommended peak power. Says NOTHING of how loud it will play, or how good it sounds. Again, power rating DOES NOT DEFINE A PRODUCT.

Why are there left and right inputs for a mono amp? If you have a mono source, can you plug it into only one input, or do you have to connect to both?

Hello. We have a using guide picture in the listing. You can check that. We have left and right inputs since some customers using stereo signal. If yours are mono, just connect one input.

When using in sub mode, which rca input to plug in? left or right or both?

Hello. Please see our second main image. The "audio in" rca posts are connected to sound sources. The "spk out" posts are a set of speaker binding posts. When in sub mode, you need to connect your passive subwoofer with bare wire or banana plug. If you still have questions, you can send your device models and images to nobsound@doukaudio.com. We will help you with it.

When using this with a subwoofer how do I know where to set the frequency cortrol knob?

Like others have said, turn volume up on your main speakers (L/R) to desired listening level then advance frequency crossover knob until you can hear the subwoofer in your favorite music passage, then back the sub down until it is un-noticeable in the passage. Your subwoofer range should take over at the effective L/R low frequency cutoff point...Blend it in seamlessly.
