Question Amplifier Making Suggestion

Hi Guys,

Lemme start by accepting that I am a dumb as far as electronic designing is concerned. But at the same time, I am an audiophile. I am in the process of making a home theatre system with 50W per channel on a 5 channel system. I have two tower spekers (Sony), gatheres a assembled 10+10 band graphic equaliser. I am running the system with a very old amp that I had in my college days. Now I am looking at making a amplifier to temporarily close the cycle.

I am in search of some suggestions and help from you guys in this direction. It would be of great help if you guys can guide me with the options available to make a amplifier of my own. If I make a amplifier with 5 channels and run only 2 channels for the time being, will it be good idea ? How would I make the 5 channels split without having a dolby/digital AV circuit in between ?

Guys, I dont understand very techy language. Please help me with this....

Thanks in Advance

Debi

Make five channels, but just don't power 3 of em up, or just connect it all, it won't matter..

5 channels requires a decoder.. 5 channel, or from your DVD player or whatever... is this the question?

Thank you SkinnyBoy,

You answered some of my questions about not powering the 3 channels.

Yeah I should have to use a decoder to split the channels. I am going in an incremental way coz out here in India, the things are pretty expensive. And can you suggest me how I should go about making a amp of my own ? Any circuits....or whatever you can help me with.

Thank you again...
