Great sounding Class D integrated. Great for a back-up or second system. This amp sounds very big with great soundstage and plenty of depth. Can be bought from Banggood. I have not tried the Bluetooth.

You will need an additional 9V power supply.

This is crazy cheap! I wish it had a wee bit more power.

Now $18.99. This amp sounds great on alnico and Omega speakers.

Just ordered one of these. Excited to try it out! It think it'll make a nice garage amp.

I have 2 of the topic amps I bought on an impulse buy.  cost me $52 shipped for the both of them.  took me over a month to get them shipped to USA.  if theres interest I might sell these two as a pair. the package is still sealed up
