This is circuit of Audio Power Amplifier use IC TDA2005, the circuit suitable for Car amplifier cos used supply 12Volt. The IC TDA2005 is class B dual audio power amplifier package specifically designedfor car radio application : power booster amplifiers are easily designed using this device that provides a high current capability (up to 3.5 A) and that can drive very low impedance loads

used a well designed quality transformer to get less noise. It will be another good way to use a sufficient battery to power the circuit. Keep the supply wires as short as possible. Input source should be isolated from the external noises too. It is recommended to use coaxial cable to connect the input audio.
