I have really good speakers but they're from an old system that didn't support bluetooth. With this tiny amp, you can turn any quality speakers bluetooth capable. I hooked this up directly to the 12 volt power in my boat.
I made this case for a TDA7492P Bluetooth Audio Amplifier Board Receiver CSR4.0 Digital Power Amplify 2*25W you can get from Amazon for $10-20. The board turns any standalone speaker into a bluetooth speaker. It's powered, so it functions as an amp too. The BT name comes up as XINRUI.
The case has openings for the power jack, speaker wires, and speaker wire set screws.
I countersunk screw holes in the bottom of the case but you can drill through the top if you wish to screw from the top instead.
