I have heard the higher voltage can reduce noise but i dont know if this is true.  It shouldnet matter what your voltage is as long as it is in the range of your amplifier.  Once you get your new headunit you are going to have to reset your gains to match the voltage of your new headunit.

Yes and this time I will do it with a meter instead of by ear, I have a question though... I read the sticky but I am a bit confused because the amp manual says that my target output voltage at 2ohm is  31.5 vac for the sub amp (TMA-T2-500.1) and 25vac at 4ohm on the highs amp (TMA-T2-320.4). am I missing something?

Thats correct you have to measure it on the speaker outputs of the amps.  Thats whay you have to use a signal generator or a test cd with tones.  The current going to your speakers is a AC current not a DC current.  Make sure when you are measuring to set your gains you have the meter in the AC setting while measuring.  Also i would use a 60 hz tone to set your gains.

I would test an array of around 30hz to 1kz incremented in 10 or 20 hz steps to make sure there is good overlap in all frequencies as well as the correct voltage across frequencies.  start with something around 70hz and then fine tune from there...
