Is it possible to have my Bluetooth Speaker and my output speakers working together simultaneously?

I have a Bose SoundLink Mini Bluetooth speaker and a output speakers. My output consists of 2 Fisher Speakers and a Kenwood Amp that uses RCA to 3.5mm audio output. When I got the SoundLink Mini, I found out that I could no longer use both speakers at the same time. I've tried doing the whole "Audio MIDI Setup" tool, that still does nothing. I'm using a Late 2012 Mac Mini, 2.5 GHz Intel Core i5, 8GB RAM, and a 733GB Fusion Drive setup. Can someone help me please..?
