Hey Guys!

I have for my room a *rare* Pioneer 280w RMS mini-type system (not so mini) and im looking for even more bass than the 2- 8 inch woofers put out. I have a speaker selector currently hooked up to it which I use to connect an additional set of BOSE 161 small bookshelve speakers to add some more sound to the other end of my room since its big. Works great and ive had 3 parties with this system to its limits without it cutting out once.

I seen a POLK audio self powered subwoofer for sale and several others of the like. How do these exactly hook up or is it possible in my case with this system? Would it connect into the speaker selector and then into a power plug?

Again, looking to work around this system and add more bass.

Thanks
