Arylic B50SE Bluetooth 5.1 Stereo Receiver 2.1 Channels Mini Class D Integrated Home Speaker Amplifier 50W x 2,Stable and Remote, Go Control Application and Easy Control EQ

Arylic B50se 50 watts, bluetooth, subwoofer-out, usb-in, has an app you can control it with and stream through. It is a great little amp. I use one on my desktop. Max watts on your speakers doesn't mean your amp can't have more. It means you just don't turn it up too loud. You might want to upgrade those once you get an amp.

the $90 Arylic B50SE Bluetooth amp may be what your looking for
