If your amplifier isn't FIT, what good is it?
Kicker DX Series amplifiers provide the utmost reliability from the biggest name in trouble-free amplification and loud, clear sound. All Kicker DX amplifiers feature FIT™ (Fail-Safe Integration Technology) to kill the noise created by the alternator, computer, and audio/video entertainment components found in vehicles today.
FIT's isolated differential inputs reject noise and electrical interference for the quietest operation possible and ultimate audio clarity. Differential inputs also make Kicker amps compatible with any factory or aftermarket radio. Stereo RCA pass-thru outputs make daisy-chaining amplifiers simple.
A muting circuit cancels out additional noise that may surge down the line, so listeners enjoy the cleanest, clearest sound possible. Additionally, a choice of three automatic turn-on modes—remote, DC offset, and signal sense—provides ultimate flexibility.
Kicker Certified Power!
Kicker's DX Series DX250.1 mono subwoofer amplifier is factory tested and certified to provide at least (and in many cases, more than) 250 watts RMS per channel into a 2 ohm load. Each amplifier includes its own serialized test certificate that documents how much power it can actually put out. Not only is this amplifier powerful, the efficient Class D topology keeps the amplifier footprint small.

Tweak Your System!
9 dB of boost (centered at 40 Hz) is switchable to add in extra bass to suit your taste. Turn on the available -24 dB/octave, fixed, 25 Hz subsonic filter to prevent harmful ultra-low frequency content from damaging your ported subwoofers. The built-in, fixed 80 Hz, 24 dB/octave low-pass filter keeps the mids and highs out of your subwoofer's operating range.
