[QUOTE="squeak9798, post: 2930105, member: 555320"] Not inherently true. Potentially a lower noise floor with the higher preamp voltage due to the lower gain setting. But if you have no audible noise with a lower voltage headunit, increasing the voltage is going to result in zero benefit. Likewise, if you go to a lower preamp voltage unit and experience no increase in noise floor then you didn't lose a thing. Remember that the amplifier gain will need to be readjusted for the different headunit in both instances. See above. [/QUOTE]
