When you add the two signals together. A linear addition give twice the 
amplitude and 4 times the power assuming the same impedance, but to 
achieve this you need an active amplifier. A passive adder will 
naturally not produce more power out than put into it, so it dampens the 
signal, but will also dampen the noise applied to the input, so the same 
relative gain remains.
