Review on 🔊 Dual Channel Mini Portable Stereo Receiver Box - 300W Rack Mount Audio Speaker Power Amplifier System with 3.5mm Input - Enhance Your Home Entertainment System with Amplified Sound - Pyle PLMPA35 by Girish Underwood

Connected to 250w Boss speakers and the sound is fine. Really just wanted to connect to a cheap digital piano to get the best sound and it does what it's supposed to and also plays any music you want to connect to it. Fair warning, if you want to use a standard power adapter contrary to the instructions, you may need to connect the orange wire to (+) as well as the red one. Black rises (-) as usual. Otherwise it won't turn on. The orange one MUST be connected to the radio to turn it on according to the instructions but who knows if that's the case or not, again the instructions aren't very good. Overall not bad for the price.
