This is a PREASSEMBLED, compact, yet powerful audio amplifier using two TDA2003 monolithic Integrated Circuits connected in bridged configuration to achieve more output power at 12V DC supply. It can deliver more than 20W of music power into a 4-Ohm speaker and is ideal for any kind of audio amplification application.
