I HAVE A ADCOM GFA7700 5.1 AMP,[150WATTS].I'M LOOKING TO GET A SET OF SURROUND SPEAKERS,GIVING ME 7.1 SYSTEM.THE SURROUNDS WILL NOT BE POWERED.MY QUESTION IS,DO I HAVE TO USE ALL CHANNELS ON MY GFA7700? CAN I JUST USE IT FOR MY MAINS AND CENTER? WILL THIS GIVE ME MORE POWER?I WOULD LIKE TO DO THIS AND MAYBE GET SOME OF THESE 200'S FOR MY OTHER SPEAKERS.OR MAYBE SOMEONES GOT A BETTER IDEA? THANKS

Or you could bi-amp the fronts with the spare channels on the adcom... I would prefer to use gonks last suggestion, using the mulitchannel for surround and the monos for the mains.

The idea of getting a set of four monoblocks for the surrounds will work fine. Another option would be to get two or three M200's for the front soundstage (mains or mains and center) and let the multichannel amp handle the surrounds. FIRST OF ALL, THANK YOU ALL FOR QUICK REPLIES,AND HELPFUL.I THINK I WILL START WITH TWO M-BLOCKS FOR MY MAINS,WHILE USING MY ADCOM FOR SURROUNDS AND CENTER-[FOR NOW].IS IT POSSIBLE TO HOOK THESE AMPS TO A SUBWOOFER THAT ALREADY HAS A BUILT-IN AMP?IT IS A VELODYNE CT-150 AT 250 WATTS. OR WOULD THIS JUST BE OVERKILL?

The sub it's normally conected to the processor or receiver using the .1 output, and if it's overkill it will be just fine.
