My IOT audios C50L- 50+50 w amplifier is awesome sound quality zero noise with 12v 3 amp adapter two 40 watt 8inch Woffer and Twitters. Do not twist the negative polls of the speakers, make them separate otherwise ic will not give you better performance to enjoy beautiful and loud clear sound with good bass. A tiny bomb of two inch size amplifier.I love it. 12 volt car battery is very much suitable for this .

Nice prodak

Man this thing is awesome if you install speakers with correct watt that matches with this amp and give it correct power supply then this thing is a tiny beast.
