I've just built a stereo amp for Mp3 playback through the rear speakers in my Volvo.(the reason for this was that I was fed up with the various interface units on sale,which do NOT work)The end result is perfect,good sound quality & volume ect.,I used two TDA2003 ICs.,& component values to the Vellerman circuit.with a 47k twin gang volume pot.It works so well I'm making another.This circuit does not require a pre-amp.There's a couple of things I want to explore,although the Vellerman circuit & the Data sheet layout are the same,there is a variation of component values,So I'm wondering how crutial are these values?also what is the purpose of the 1 ohm resistor & 0.1 cap between the output terminals?Any suggestions are welcome.
