[QUOTE="Lasherž, post: 8712894, member: 679555"] I'm partial to bass boost. Obviously if your setup is good you won't need it because the enclosure will fill in that dead spot. The input signal isn't what's clipping, it will be the output channel. Like in other scenarios you can check for output signal clipping with a multimeter and various 0db sine wave tones. It's true that it "stretches" the signal, which is always a negative thing for clarity, but I'd rather have a slightly stretched previously clean signal than an overly boomy midbass followed by an underwhelming low bass in enclosures that offer no resonance in the low end. By using the bass boost knob you're sacrificing volume in more efficient ranges and signal clarity for equal volume between high and low in an over-dampened enclosure scenarios. That is if you correctly set it up to avoid clipping. The clip lights make it much easier since you can tune for flat response through sweeps while being mindful of clips. Distortion is a whole other beast, but provided your signal actually contained audible bass in that frequency before you modified it I don't believe the boost knob will distort it to the point of harm so long as you don't clip it. The worst case scenario for distortion would be if you use an lc2i to boost bass signal that was all but missing from the head unit source for those two speakers and then further bass boost it using the amp. Alternative if your head unit has a very weak pre-out voltage. You can't expand on a signal that's not there and expect it to be clean still. In that scenario the primary quality loss would be from the LOC resurrecting a signal that was hardly there, not the bass boost further stretching the undead signal, but they both contribute to the issue.
