Guys,
i have an issue and not quite sure what is causing it, but lets see if somebody has come across it.
Working with no issues using CSR8645 bluetooth amplifier board. Noticed that youtube has tried to mute the sound a little on a few songs so please disregard the poor sound.

I've currently tried boards from various sources and get the same issue on all but one board.
CSR8645 (have 3 of them, one works flawlessly in above video)
CSR8645 Bluetooth V4.0 Amplifier Board Module APTX 2*5W for DIY Bluetooth Sound Box
and

QCC3003 Bluetooth Audio Receiver Module
QCC3003 Bluetooth Audio Receiver Module 5W+5W Power Amplifier Stereo Support Call BLE5.0
and
SANWU-HF69B-6W+6W (only have one)
SANWU(R) HF69B 6W+6W Dual Channel Stereo bluetooth Speaker Amplifier Board Power - US$7.46
I've been wanting to run a low powered bluetooth speaker setup just using a solidarity 18650 batter and a single speaker. All builds were based on AUKITS bose clone where a step up module was used to go from 3.7v to 5-6.5v which all boards can handle, and all but the SANWU were to have a 2000uf capacitor across the VGC, GND connection onto the board. The problem i'm encountering on all 4 boards is once the volume goes past 3 quarters volume or something with a bit of bass, the unit restarts and sometimes cannot reconnect. I dont know if the problem is specific to using these boards as the green one in the video does not experience this.
My thoughts is potentially it is due to the supply potentially, but as i removed the step up module for a test and changed it over with the DC\DC isolator i'm not quite sure. As it restarts, it could be under load and have a protection circuit or something on board, but i just dont know. The SANWU i havent had any luck with, but have seen a guy add some extra capacitors to the board, but i dont think it was for the same issue.
below somebody else's experience with the board.

I do realise i'm using no name chinese gear and it could come down to quality control or just the person i based it on could have got it from somebody else and have a slightly different board, but any advice for this noob would be greatly appreciated.
If i can finish my last project using one of these 4 boards successfully with an addition of a capacitor or something would be awesome.
