Hello,   Currently, I got a 15 inches speaker (JBL Eon615), and I would like to put a cable in it and connect into my phone and play some music using Poweramp for Android. And simultaneously, I would like to remote control it from another phone, so it is more comfortable, then would be possible to change the music from a coach or wherever I am.   Basically, I would like to request a phone to phone remote control to be able to remote control Poweramp - I suggest Bluetooth, Loc
