Default cheap TPA3116 2.1 amplifier with bluetooth

Hello everyone

I'm looking to build a cheap 2.1 system.
I'm not specially looking for something loud as I live in a apartment.

After a long search I came across this one :
Hifi MINI TPA3116 2.1 200 w subwoofer Bluetooth 4.0 stro numrique audio carte amplificateur de puissance dans Amplificateurs de Appareils lectroniques grand public sur AliExpress.com | Alibaba Group

its cheap, it has bluetooth and a line in.
but does it sound any good? would you recommend something else?

also what kind of power supplier should I use?

thanks

I have a very similar board w/o the Bluetooth. The board in the link has a slightly different payout (aside from the BT). I've only used my board for testing but am pleased so far.

Any laptop top power-brick (-+20volts) will suffice for this type of module.

ok thanks for your reply.

if I want a TPA3116 2.1 with bluetooth in a finished case it cost around 50euro without the charger New TPA3116 2 1 Bluetooth Amplifier Board CSR4 0 Class D 100W 50W 2 Amp Board | eBay

so total price will be around 70 euro for a TPA3116 2.1 with bluetooth + case + charger.


maybe better to go directly for something bigger like Jie CHUANG JC SZ80A 80 W + 80 W Bluetooth 4.0 pur amplificateur de puissance numrique Fiber / coaxial / USB ( soutien mobile OTG ) / Bluetooth dans Amplificateurs de Appareils lectroniques grand public sur AliExpress.com | Alibaba Group
for a few more euros, there is a dac usb, digital line in, remote... ?
