Injecting one sub to Benchmark system…

Noob here and just hooked up my new Benchmark AHB2 and DAC3 HGC with pair of Totem1 bookshelf speakers.

I have a Velodyne SPL-R series subwoofer and would like to connect this. I’m seeing a lot of varied advice on the web on how to do this and thought I would come here for better advice.

Not even sure if the sub would connect to the preamp or the amp….any suggestions?

cheers
