Hi Almarg, the sub has a two prong power plug however the amp uses a three prong plug, maybe I'm ok there as you mentioned, thank you for that.
Yes I would be connecting the speaker wires coming from the amp to the high level inputs of the sub and then the speaker wires would be connected to the high level ouputs of the sub.
On the other question, let me clarify, although the amp and preamp are a balanced design, it is not being used in balanced mode but just using the rca outputs of preamp to the rca inputs of the amp. I am not using the balanced feature of either the preamp or power amp. If this makes a difference.
I don't know if the amp manufacturer is making a warning to the connection of high level (speaker wires) or low level (rca) input connections to a sub, maybe either can pose a problem if the sub has a common ground.
