I'm using a Parasound Zamp v2 right now with some bookshelf speakers
Would like to add a subwoofer to the setup, but there aren't any sub-outs on the amp.
Is there anyway to hook up a powered sub? The only open jacks seem to be a pair of loop out

You'll need a sub with a high pass and low pass crossover with speaker level inputs.

Connect speaker levels to sub, then set high pass and low pass on the sub, connect the bookshelf speakers to the subs speaker out. This is the only way you can do it properly.

The shortcut method is to find a sub just just a low pass and speaker level inputs (The Velodyne VX10 is an affordable option tahts pretty good), connect the amp to sub, set low pass crossover based on your bookshelf speaker response, and then connect speakers to the sub. This will work as well but you will probably not get a perfectly smooth frequency response.
