What I have done:
- Ordered a REAL bluetooth adaptor:
https://www.youtube.com/watch?v=3Am9psYGt2E - $30 here in Australia
- Got a nice 5.1 old system on ebay or similar just for the amplifier- Here paid $50 for it
- Ordered a nice old pair of Sony speakers - paid $30
Voila! Plug your new speakers and blue tooth to the amplifier. Done!
Got a nicer clearer sound than these modern shitty boom boom boxes for 5 times less the retail price!
Can listen from mobile, PC, etc...
Also decorates your living room once you find a way to hide the amp. Speakers serve a way to put your plants, etc etc...
