So I am looking to get some surround sound in my room, but I'm having some difficulties. I have a Bluetooth sound bar already that I use to listen to music in my room. The only thing you can use to connect it to something is the aux port. I was wondering if its possible to connect it to an amp, that's already connected to 2 other speakers. So I could connect to the amp using Bluetooth, and have it play sound through the 2 wired speakers and the sound bar.
