    I know this is probably a stupid question, but I'm trying to figure out how these things work.

    If you have a 100 watt per channel receiver and you add a 5 channel amp at 80 wpc does it increase your per channel power to a total of 180 watts or are you bypassing the internal amp and getting 80 wpc from that external amp only?

    Thanks for the links Vince!

    Some related questions.

    1. So is an external amp always going to give you better quality sound and more power even if its wpc is rated lower than your receiver?

    2. In one of the links it mentioned that 4ohm speakers needed twice as much power as 8 ohm speakers. I would assume then that 6ohm speakers would take 1 1/2 times more power. If this is the case then my 120 wpc receiver isn't truly going to give me 120 wpc unless I am using 8ohm speakers and in fact may only give me the equivilant of 90 wpc when used with my new PSB speakers which are 6ohm. Is this correct?

    Personally I believe a stupid question is usually one that is asked after the problem has occured which is what I am trying to avoid.
    My Kenwood 1080VR receiver only refers to the channels being driven 120 W each at 8 ohms so should I keep a fire extinquisher near by?[​IMG] or better yet use this as an excuse to my wife that I need to upgrade my receiver now due to my ignorance?

    I called Kenwood technical service and the guy said I should be fine under normal listening conditions. He also said the reciever will automatically power down if it can't handle the load.
