Reply to Traktor / Abelton/Soundflower Very Quiet Output

I have been experimenting/messing around sending Traktor though soundflower into ableton (been using ableton for different effects) and out to my Db4 but the audio is very quiet coming into the Db4 , I need to have the gains cranked way up to get the leds on the volume faders to show above 0 into the + area . Anyone got any ideas I am pretty new to ableton so not sure what setting to change .
