Why have the subsonic filter OFF when you're trying to avoid playing low notes?yeah its hard to tell what you have them set to? i would do like deuce said set the amp gain to 1/2 and adjust the remote gain til u see the red light, thats how i did mine. and when i first got mine i had the lpf too low lol. i would probly set the low pass all the way up and subsonic all the way down first,then adjust them later to like 30hz and 80hz
