newbie I need help in assembling a amplifier

[neilrayer]

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.

I have Yp 20watts 4inch speaker and brandless,10watts 2 inch speaker and philips tweeter.. each a pair.. and a 80watts, 6 inch daylton sub.

I'll suggest LM1875 stereo and TDA7294 for subwoofer. Both chip can run on +/- 25V DC supply you'll need at-least 150VA transformer.

can i get LM1875 WITH TDA7294 IN Chennai or anywhere in South India or online?

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.
