[QUOTE="shizzzon, post: 7462885, member: 590338"] preout voltage has nothing to do with getting louder on the meter... All it does is allow the user to turn the gain down on the amp to match the HU's output... And since the gain on an amp isn't a volume control.. that is also why i very rarely will ever recommend anybody using a line driver unless they are running a LOT of amps and the signals going into them are virtually non-existent. Now, having the gain cranked to max may induce, "MAY", a light amount of noise but doubt it would be audible. I would look into the settings on the headunit itself. Sub level output bass setting Loudness EQ All of those things can have an effect on the sub's ability to get loud or less loud. Assuming you have changed absolutely nothing except the headunit.. check those things above. Also, it wouldn't hurt to check to make sure both channels on the RCAs are plugged in and working from the headunit to the amp as well. If one of those channels is dead, then you would only be getting half the signal which would force you to crank the gain a lot higher to match preout voltage. [/QUOTE]
