Before you shoot me, as this topic has been covered many times, I did do a search on this and read about 20+ threads on this subject before posting .
Here is the deal:
I currently have a Carver 5 channel amp capable of doing 125 x 5 @ 8ohm with all channels driven. It is connected to a Integra receiver. I currently am only using it to drive my front 3 speakers and dont really plan on changing that. I figure the Integra which is rated 125x7 can handle a pair of Monitor 40 surrounds in a 5.1 setup without any issues, especially since thats all its got to power.
The current speakers for my Left and Right are Monitor 60?s which are 8 ohm 90db efficient speakers but am looking to upgrade my fronts in the next couple months and not sure what efficiency or ohm rating I will end up with yet...
Here is the question: Is it better to use just 3 of the 5 channels, or is it better to use all 5 channels and split the Front Left and Front Right signal to 4 of the 5 channels (2 channels per each front left/right speaker + 1 for the center) using only the Carver amp?
I am wanting to make sure I am not limiting the power draw ability of the low frequencies (which you need more power to produce) to give power to the highs/tweeter (which doesn?t draw nearly as much power as the lows). My thought is that if I am only using 3 channels it allows each channel to have a higher wattage of power to draw from as needed and that using all 5 channels changes this a bit.
But since the speakers only draw what they need shouldnt adding the tweeter on its own dedicated channel on the amp not make a big difference due to the small power draw it has?
Also if I get speakers that are not as efficient as the Monitor 60's would running 2 channels of the amp to each of my Left and Right speakers be more worth it than my current situation or no?
I am currently running 2 channels from the amp to each Left and Right and while it seemed to make a difference to my ears, I am not sure if I am just not hearing what I want to hear to justify running it this way.
