What amps and watts we need for this mini amplifier

[binduvenugopal]

Is this have a good bass and sound quality

[shanav]

These ic will burn of i think because this board can only 3watts and its a good board for 3 inch speakers more then that will give you small volume and if you are makeing an portable or an bluethooth speaker with 3inch speaker its good and 4 inch can also give you sound but the volume will decrease and i can tired it. It can only output 3watts. If you want more than than you can use tpa3310 which gives you 15 w of output which has super sound quality and many safety features
