I have a home theater system with wired speakers and I bought the AR Hatteras wireless speaker. Both work off my iPhone 6S separately with no issues, but when I plug in my iPhone to play off my stereo and my wireless speaker it disconnects my wireless speaker. I don't understand why this would happen since they both have separate amplifiers, why won't both my stereo speakers and my wireless speakers work at the same time? Any solutions to this issue?
