    you would be better off using a seperate amp on your center and your left/right and you can let the amp in the 803 power your rears.

    If you get a 5 or 7 channel amp then don't use the onkyo at all. A good seperat amp to start with would be Emovita or Outlaw. If you have more money to spend you should think about B&K, Rotel and Sunfire. It depends on your $$$.

    Forgot to tell you how to do this. It is easy. Just buy 3 or 4 sets of good rca cables. run them from the pre out on the back of your avr to the input of the amp. If you want color coded cables go to Blue Jeans cables and I think they have color coded ends to keep everything straight.

    I second T..03's suggestions above.

    The 803 should be able to run your surrounds. Get a 3 channel power amp. What you will do is run RCA cables from the Onkyos Pre-outs Left/Center/Right channels to the appropriate RCA ins on the power amp, you will wire your Left-Center-Right speakers directly to the power amp and the Onkyo will control the volume and equalizing functions, etc. This assumes your surround speakers are 6-8 ohm impedance loads. If they are 4 ohms or less you'll need amplification for all speakers!

    Currently if I'm not mistaken, one of our members is selling a nice 3 channel Aragon amp that would do you fine. Look through the threads or use the search function to see if that amp is still for sale.

    Also, check out www.audiogon.com for primo used power amps at good prices. Welcome to the club and check your wallet at the door!

    Don't know that....it's an older model...might be OK if we knew what it puts out per channel...8 ohm, 4 ohm, 2 ohm? No specs on ebay site. Maybe you could ask the seller!

    Or someone else here knows???

    Shondoman..

    That doesn't make any sense. 150 at 8 ohms should be able to handle those speakers unless the guy who owns it is running the amp to the clipping point? Or the amp needs WORK!
