hey, u can just go for 5 Nos LM1875 for all speakers and a LM3886 / TDA 7294 for subwoofer...
a lot of LM1875 circuits layouts are available on net, so u won't have much problem making it.. LM1875 costs 45-50 Rs per chip, TDA 7294 is for 90-120 Rs.. and LM3886 is around 150-220 Rs.. so go ahead make yourself and have fun...

if you can spare a 1000 Rs, i'll suggest to order 7 samples for LM3886 from Naitonal semiconductor directly and make a 5.1 setup from this... use 2 lm3886 for the subwoofer and 1 each for 5 channels.

post reported.
I thought about reporting it yesterday, but some Members consider me to be an interfering self appointed policeman.
