I think you´ll have to go into every .prs file and find the "[spl] xxx"-line and change it to your preference, I belive the [spl] should read out as "speakerlevel". I remember doing that when certain modded ACs produced soundlevels far above the main levels of other ACs long time ago. It´ll be some timeconsuming handywork but it might be worthwhile. Hope it helps. (By the way the prs files are found in the Mods/STD/presets/sound folder or root 1946/files/preset/sound)
