I have a Sony STR-DE545 Stereo Receiver with 5.1 capability that is beginning to have occasional dropouts of audio. I can't afford to have it repaired. I also have a Sony STR-AV900 Stereo/AM-FM Receiver that I used before I got the DE545.

I have 6 speakers: 2-front (R-L); 2-rear (R-L); Center; and Sub-woofer. I would like to connect all the speakers to the AV900 and then INPUT audio from my TV, CD/DVD player, VCR and Verizon TV service. Is there some way to do this by connecting the various speakers in Series/Parallel, etc.? If so, can you recommend the configuration. (The speakers do NOT MATCH--except for the 2-front and the 2-rear--and the front and rear do not match.)

I have read about impedance settings and do not know the impedance of all the speakers.

My major use has been playing the TV audio thru the DE545 and occasionally playing the Verizon TV service AUDIO thru the DE545 for audio only.

Can this be done? Or, will I only be able to use the 2-front and 2-rear speakers with the AV900 which only has outputs for 2-front and 2-rear?

Thanks for your input.
