im back wth a noob question!

[i JACK o]

philosphically speaking if my recieve could produce 100 wats of power to my speakers and an amp could produce 300 wats to that same channel, would the reciever and amp work together to producea total of 400 wats to that 1 channel or would the amp do all the work in turn only giving the channel 300 wats

No. The amp will do all the work.

When using a receiver as a pre/pro you bypass the internal amp of your receiver when connecting to an external amp.

Generally speaking, it is not a good idea to connect two power sources to the same speaker unless you are bi-amping. If you are not bi-amping and connect two different type amplifiers to the same terminals of a speaker, the stronger amp will see the other amp as a load and will try to drive it.

Furtermore, when you are adding two 100 watts power sources together, you will not get 200 watts. You will get 400 watts.

This is Big Daddy's new math:

100 Watts + 100 Watts = 400 Watts

First of all, you cannot add power or Watts. Power and work do not exist until some action takes place. In the case of speakers/amplifiers, you will need to add voltages.

Assume we are adding two 28.3 volts to an 8 Ohms load. The relationship between power and voltage is as follows:

Power = Voltage^2 / Resistance

Therefore, 28.3 volts is equal to 100 Watts for an 8 Ohm speaker..

Power = (28.3^2) / 8 = 100 Watts

When we send two 28.3 volts to the same 8 Ohm load, the total voltage will be 56.6 volts.

Total volts = 28.3 + 28.3 = 56.6 Volts


Total Power = (56.6^2) / 8 = 400 Watts

It is all magic.

Big Daddy math!

thanks for the extra details, details are good

So breaking it down for us non-rocket scientists you could substitute this formula.

Problem -> a miracle happens = 400 watts!

If you look at the specifications of most amplifiers, you will notice that when you bridge a 100 watt per channel stereo amplifier into mono mode, you will get up to 4 times the power rating. Of course, this assumes a perfect amplifier with a perfect power supply and a wall outlet that is capable of providing as much juice as the amplifier needs.
