A:AnswerNo, not @ $49.95 or so. It has a wireless remote, though. And you could hook up a device with the proper mini-stereo cable if your phone has the out jack on it. I've posted in other questions that the speakers on this is atrocious. However, I connected the speakers from its predecessor which sounded great.
A:Answer16 or 18 gauge. Add? No. Only two slots. However, the speakers on this unit are bad. They are removable, though, sliding up and off. My old system was failing in the tuner section. So, I snipped the speaker connectors off the new speakers and spliced them on the old speakers and the difference was amazing. Otherwise I was going to return this unit. Worked out with better sound!
A:AnswerUnfortunately, this unit has a Bluetooth receiver and not a transmitter, therefore, it can only receive Bluetooth audio from a phone, tablet, etc., and play the audio out loud.
