I am living in pondicherry, India. I assembled a lm4440 2.1 audio amplifier. I am not satisfied with the audio quality. So please suggest me good audio board available in shops to assemble. and the power supply to it. I need around 20w stereo and 30w-50w sub. I need high quality sound output. my budget is 1000rs. please help
Unless you missed a zero that's decidedly more a mid-fi budget. If the priority is truly quality 2 Modulus-86 + Parallel-86 + Power-86 would be a good starting point, maybe give or take a board selection as post 1 neglects to specify impedances. +30dB over 1000rs just for the boards, though.

What kind of speakers will you use with it?
Ok i am satisfied even with 10w.. stereo.. can I get a high quality audio.. a ready made speakers or assembled amplifiers?
I'll suggest LM1875 stereo and TDA7294 for subwoofer. Both chip can run on +/- 25V DC supply you'll need at-least 150VA transformer.
If you are looking online, look at Eight Audio they have audio premade kits available. If you use TDA2050 instead of LM1875 from eightaudio then use 15-0-15 transformer for it.
