    Amplifier Rocks
    This amplifier rocks I have it running to a Kicker solo x18 and yeah you would think a subwoofer that is rated for way more power would not do much with this amp but, god, it pushes that sub like its nothing and there is no distortion I can hear. This is one hell of a good amplifier I love it I would buy it again!
