hi
i have the application data book , these ic are cheaply available here and have constructed a few , stability and ease to construct is commendable
but
sound quality is far from anything good , they were designed for tvs _ built in speakers
has no bass drive about an amp and a half or so
mainly the sound is not accurate the bass delivered gargles and is boomy on a punchy as well as a deep track
i advise you to go in for a darlington design , few components , descrete and powerful with fine accuracy
