what is the point of running a 4 pill amp after a 2 pill radio???
you have basically made a 2 driving 4 amplifier, which is a crappy design from the get go.
it is a great way to make your wattmeter lie to you though!
the 2 pill driver section drives the 4 pill section right into saturation and they start spewing harmonics which make wattmeters show more watts, but doesnt help your signal one bit.
if a 2 pill amp does 150 watts PEP, then the equivalent 4 pill will do around 300 watts. about a 1/2 an S unit increase.
if your 4 pill seems like it will do a lot more watts than double the 2 pill output, then the transistors are being driven into saturation and your wattmeter is lying to you.
it sounds to me like you are overdriving the input of the amp in order to see numbers on the wattmeter that allow you to believe that its worth it to have it in line, but that is not the truth.
the truth is, if you just run the radio with the power up at a normal level, then you are doing just about as well as with the amp in line.
probably putting out a much cleaner signal also.
