A:AnswerTo be honest Im not sure but I doubt it . I had no luck getting my unit to connect to bluetooth with my iphone SE. I did however use a 3.5 mm RCA cable to connect my phone and other devices to the stereo for music .Which works well and is said to provide better sound. Some people claim the bluetooth range is poor and is frustrating so beware . This is a decent unit for the money and gets fairly good reception with the provided simple antennas . Im happy with my unit .
A:AnswerNo, you cannot. However, you can connect a powered subwoofer with high-level inputs up to one of the zones, if you desire heavy, resonating bass.
