if your laptop internal speaker sound very low then dont b upset here is a simple audio amplifier using IC 4440 gives up to 40W of power which is amazing for normal use .... <br />i used 4ohm 40w sub-woofer but this IC can also give up to 100W with some modifications... <br />i also attach a circuit diagram with components detail so if some 1 is interested then i recommend u to must try it...it cost very less. <br />And it also a perfect match with mobile phone , make your party super by playing on mobile.
