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 DX400.4 four channel amplifier is factory tested and certified to provide at least (and in many cases, more than) 100 watts RMS per channel into four channels at 2 ohms or 200 watts RMS bridged into two mono 4 ohm loads. Each amplifier includes its own serialized test certificate that documents true power output.
Example from a Kicker DX200.4
Tweak Your System!
Use up to 18 dB of boost (centered at 40 Hz) to dial in extra bass to suit your taste. Two switchable crossovers are built into the DX400.4: a 12 dB/octave high-pass filter with variable frequency control from 50 to 200 Hz for front stage and rear fill use, or a 12 dB/octave low-pass filter with variable frequency control from 50 to 200 Hz when using the DX300.2 as a subwoofer amplifier.
