Here's my experience with different pre-out voltages.
Have an Excelon with 4.5v and was running a sealed Tempest that sounded very good and hit pretty hard.
Move the sub/amp into the GF's car with a 2v Pioneer HU. Reset the gains correctly with a DMM and the sub sounded like crap!!! Just hollow and empty with NO impact. Tried turning up the gain and no difference. Messed with the EQ settings for hours on end and it still sounded like crap. Gave up for a few weeks.
Then I decided to try the "forbidden" and used the loudness button on setting 2 and the sub came to life. Also made her coax's sound MUCH better. What exactly does the loudness button boost?
Any ideas on why her HU made the sub sound so bad/have such little output? The only real difference was the pre-out voltage...//content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif
