so i am new here, and i would like some help on my little project... i want to make a boom box, powered by a 12 volt battery, and i would like a 25-50 watts of power to the speakers... can anyone help me find a chip, that would not be hard to find?
also a schematic of application would be nice

needs >12Vpk into the load.tda8560 , 40 watt into 2 ohm. stereo.
Is this a bridged output?
What supply rail voltage does the manufacturer use to arrive @ 40W into 2r0?
Can you see that you cannot get 12.6Vpk (doubled for bridged) from a 12V battery?
Probably not since you have posted the wrong formula for power.
9V & 4.5A is for continuous non varying DC power.
9Vac & 4.5Aac is for alternating current power.
9Vac is >12.7Vpk, 4.5Aac is >6.3Apk.
The power that results from these values is impossible to get from your chipamp.

i actually wanted to ask one more thing... i want a volume control with my device, but with 2 channels its a bit more complicated... how should i do it?
With a two channel volume control.
well i just put to gather the schematic, and it works \o/
there is one problem though... if i turn up the volume on my phone (with wich i tested the schematic) by a few ticks, the sound stops (and the microscheme starts to heat), until i turn it off and on again.
(I am using a 15w 4ohm speaker.)
(is there a possibility, that the speaker drops its rezistance to 0, if it gets too much power, so it doesnt rip, or burst?) this actually seems quite impossible
how to avoid this problem?
