I have a new garage system A speakers mounted inside my garage, B speakers mounted outside my garage facing the backyard. I want a little extra low end and have two unused, powered subs that were part of standalone systems. One is a wireless sub from a soundbar system I don't use anymore (but it rocks), the other is the sub from the wired Klipsch 2.1 promedia. The Klipsch would probably be easier to rig, but not sure either would be ideal. I'm just hesitant to purchase a new sub when I have two existing, and great-sounding subs in near-new condition. Anyone have any ideas?
