pls. help me with an audio amplifier circuit that can boost my car radio to 30W or greater.Thank you.
 
Why only 30W?
Most car radios are advertised to deliver 200 Whats. They actually deliver about 14 Watts RMS continuously to four (they have 4 channels) 4 ohm speakers over the 20Hz to 20kHz frequency band with low distortion.

If your car radio has four channels and your speakers are each 4 ohms then already the radio produces 56 Watts, or 200 Whats.

If you double the power then the sound is only a little louder. Ten times the power sounds twice as loud.
 
Why be such a wimp? Go for a kilowatt per channel, then you'll be the envy of the neighborhood. Can you afford several thousand dollars per channel?
