Default few questions about TDA1554

Before i start with building a tda1554 amp i want to be sure what i'm doing.

I am working by this shematic:

22 Watt Audio Amplifier

1.Would 12V 1.25A adaptor be enough to power an amp?,i don't want to listen music on max level.
That adaptor powered divoom morro 123 speakers and it was wery loud

2.where to place potentiometer, to control both L and R channels?

3.is it just loud, or very loud?

4.i really cant make a pcb for it,so where can i assamble the circuit?

TDA1554Q is car amp & can be listen in home environment. The Max power supply is 18V (Single supply). It was my first amp. Total area of car & home is different so it is not very loud in home environment.

3.is it just loud, or very loud?
It may be loud when you use efficient speakers and very good power feed.

Attached pcb layout for 2.1 and can be alter to make stereo mode.

One thing, if you already purchased 1554q and want to build go for something like this.

Build as per schematic don't skip bypass cap, mount chip on bigger heat-sink. The chip should run cool enough to touch with the proper heatsink installed.

The pots go before the input (220nF) capacitors. If you build a 2.1 system, they should even go before the active crossover.

You should add C5 anyhow, but it will probably not solve your noise issue.
