Good day, new member here from South Africa, need some help with a small project I'm busy with, I've got a small Bluetooth speaker that I've stripped and I'm Rebuilding it, I've added 2 additional amplifiers as I've added extra speakers and increased the battery capacity, but that's not the problem, everything works besides the fact that I need a clear audio signal for the additional amplifiers I've added, is there someone here that can maybe tell me where on this pcb I can get a clear signal? I've added some photos, thanks.I need a L,R and a ground.
