you better reread my post.

until i get a new prepro, i'm running separate preamp and power amp.
They're from the 1980s and don't have a sub out.
the simplest way to make connections in my case was using the high level inputs AND outputs (speakers connectors on the sub):
Power amp TO sub's high level inputs;
Sub's high level outputs TO main speakers.
when done, i adjust the sub level with the level control on the sub to match the main speakers' levels.
You also need to adjust the crossover freq. on the sub itself for a "best match".

speaker wire needs to be used for those connections.
