Guys about 3 years I purchased a Bluetooth device to enable Bluetooth from my phone to my lanai area. It worked good up until a week ago. I called Crutchfield for advice and I have a bad unit. It is still in protect mode with all speakers disconnected. So I’m in the market for something new. Any ideas. I am running 4 speakers Polk audio at 40w max. So basically 4 channels. What they recommended was 1300 but I just want it to play music from my phone to the patio area through the speakers. Anyone have a economical unit that they purchased from somewhere else
