Excellent product with good bass and very small too but very POWERFULL. I connected 1 30watt subwoofer and 1 speaker in parallel and used 14.8 Volt, 2.5 Ampere power supply and it worked perfectly.
Edit:Now, i use it with 19.5v 3.33Amp laptop adaptor and i am getting full 60 watts output from the amplifier with excellent bass. Also you need to give input through Aux which is about 1.5volt which you can give only through TV, laptop or bluetooth card. It won't give full sound directly through m...

The first amplifier board that I bought a few months ago was very good but the second time I have bought was a rubbish. It sound is very low and when I turn up the volume it didn't work. I didn't expect this type of product from flipkart 😞😞😞😞😞🥺🥺

Good

Powerful sound with amazing bass , I am using 24v 5amp SMPS , go for it

This little amplifier is very powerful , I am using a 4 ohm 6 inch speaker and 12 volts 5 Ampere power supply and the amplifier is running cool. No heating at all even at high volume

Nice product but SMD coil is over heat

Sounds good
