High quality low price
Very good product. Anyone with little electronic circuit knowledge can use it. I am using it for Bluetooth purpose. For Bluetooth I am using a ROBOSTER Bluetooth Stereo Adapter with 5v available from the circuit. The sound is very loud and crystal clear. Knobs should have been supplied with the volume controls. Overall it is a beautifully designed audio amplifier at a low price.

Absolute cheating
Better products are available in local markets below 200 rupees. There is no option to affix potentiometer in the cabinet . It is not 100 watts. Low bass. Sound quality is good but not upto the price. The most important problem is overheating. It can be played maximum of 1 hour continuosly.

Absolutely useful for beginners
This is completely useful for making portable speakers or desk speakers. You just need 12v battery to power it. It has volume control, treble control and bass control. All wiring done from seller only. A quick guide is provided to identify wires.
