I have one of TPA3116 Turn-On Thumps for long time, powered with a15v 2 amp power, it works just fine, but the bluetooth worked before only with a 12v power, I tried with a 24v as well, and after turn it on and off for a while, it kinda works, but just for a while. Is there any way I can fix that? or is there any way I can turn on and off the bluetooth when I want to use it? I've been using the output hooked up in my tv, but it would be nice to have the bluetooth function as well! and a Last thing, is there any way to custom these unit to receive to inputs? Best! Thanks!
