[QUOTE="trumpet, post: 8162606, member: 628688"] "Gains all set at half" - this is your problem If the sub is actually bottoming out, meaning you've looked at the sub and it's looking like the cone is trying to jump out of the box, you're causing damage. The bass boost or EQ knob is best left at 0. The low pass filter might be fine where it is, but that can be addressed later. The gain or input sensitivity knob is not your volume knob for the amp. It's to get the input section of the amp matched to the voltage coming in from your head unit. Turn this knob down and I think you'll find the bass sounds better. If, after changing the settings, you want louder bass you need to change your equipment. A ported box designed for the sub and for the sound you want will be louder to your ears without changing the amplifier or the sub. Something to try that won't cost anything is to change how the box is aimed and move it around. [/QUOTE]
