Actually, this can be attributed to the fact that every noob and their mom buys Kicker because they know they can be loud for cheap. These are the same people, however that think the gain knob is a volume control and that remote bass knobs
make their system sound good. The reason so many are for sale with one blown is these morons keep screwing with the settings after someone who knows what they're doing installed it for them, or they and a buddy installed it and wired it backwards or at .5ohm with a BS "1600w" amp with 40A of fusing that has a damping factor of 40 and sends straight clipped after 300w RMS
i have only ever had one good experience with kicker. some old xpl 12s. pounded like crazy for bein on a alpine mrp 500 and good lord the sq was out of this world, but those were oldies and goodies, they dont do em like that anymore.
