A kilowatt of bass power

For some people, great bass is what makes life worth living. Kicker built their DX1000.1 mono amp to send up to 1,000 watts RMS to your car's sub system, so you can feel the low-frequency joy, too — all from an amp with a footprint that's about the size of a piece of computer paper. You can harness this awesome power with a built-in low-pass filter that tailors the bass notes you send to your sub, while the subsonic filter removes the super-low frequencies that your sub can't play. A bass boost lets you add some extra bump in your music, and the remote controller lets you control the amp's level from the driver's seat. You'll also find the set of preamp outputs handy for getting signal to another amp in your system.

Isolates and eliminates noise

You want lots of power for your subs, but this Kicker DX amp gives you something extra — clean power. Kicker's FIT™ — Fail-Safe Integration Technology — rejects noise from alternators, audio/video gear, and other car electronics for crisp, clean operation, and accepts a wide range of signals so you can hook up the DX1000.1 to almost any stereo.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

CEA 2006 Compliant: The Kicker DX1000.1's power and signal to noise ratio are measured according to CEA 2006 standards (Consumer Electronics Association). These standards allow you to accurately compare the specifications of all CEA 2006-compliant amplifiers, even if they are different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The rated power output is 550 watts RMS x 1 channel into 4Ω (20-200 Hz, <1% THD+N). While the CEA 2006 S/N is 75 dB (measured at 1 watt), the S/N at rated power is >95 dB.

Kicker Livin' Loud Certified Power: The amplifier comes with a certificate that indicates the total maximum wattage of the particular amplifier, along with the model number, serial number, tested date, and whether the amplifier passed the total harmonic distortion, signal-to-noise ratio, and protection circuit tests.

Protection Circuitry: The DX1000.1 has protection circuitry that will turn the amp off in the event of overheating, over voltage (power input), under voltage (power input), short circuit (speaker output), and over current (speaker output). If the Protection LED on the left side of the amp illuminates red, the protection circuit has engaged and the amp will not play until the problem is resolved.

Fail-Safe Integration Technology (FIT): To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the DX1000.1 utilizes Fail-Safe Integration Technology (FIT), offering isolated differential inputs for significant noise reduction, and compatibility with virtually any factory radio.

Speaker Level Input: High level inputs can be used when the source device doesn't have preamp level outputs. The same RCA inputs on the amp are used for either speaker level or line level connections. When a speaker level signal is used, speaker wire to RCA adapters are needed (item number 20609ZISL, sold separately) and the Input Level should be set to High.

ZXRC Remote Bass Control: The DX1000.1 comes with the ZXRC Remote Bass Control, which allows you to control the output level of the amplifier from the front of the vehicle. The wired remote comes with a bracket to mount it under the dash. The supplied 18' cable, with RJ-25 phone plugs at each end, connects the wired remote bass level control to the amplifier.

Note: The Remote Bass Control measures approximately 2-1/4" wide x 1-1/4" high x 1.75" deep (2-3/8" deep including the knob and wiring).


Gain Control: With the Input Level Control switch at the appropriate setting, you can set the rotary Gain Control to match the output of the source unit. The Gain Controls are adjusted with a flat-head screwdriver and can be set between 0 and 11.

Input Level: The input level control is switchable; when set to Low, the amp can accommodate a line level input signal of 125mV-5V, on High, the amp will accept a 250mV-10V speaker level signal.

Auto Turn-On: The Auto Turn-On switch offers three options:

  • +12 V: the amp turns on when +12 volts is applied to the remote terminal
  • DC Offset: the amp turns on when a 6 volt surge is detected on the signal inputs (from a speaker level source); in this mode the amp's remote terminal acts as a +12 volt output to turn on another component
  • Audio: the amp turns on when an incoming audio signal is detected; in this mode the amp's remote terminal acts as a +12 volt output to turn on another component

Low Pass Filter: The DX1000.1 is equipped with a low-pass electronic crossover; the crossover point is continuously variable from 50 Hz to 200 Hz and the slope is 18dB per octave. Properly set, the low pass filter creates a smooth transition between the subwoofer and the sound system's full-range speakers.

Subsonic Filter: Frequencies that cannot be reproduced by the subwoofer do not become sound, but unnecessary oscillations causing distortion; these frequencies also waste amplifier power and can damage speakers. The subsonic filter removes the frequencies below the crossover point to improve the performance of the speakers by eliminating this harmful distortion. The 18 dB/octave subsonic filter's crossover point is continuously variable from 10 to 30 Hz.

KICKEQBass Boost: When you want more bass from the amplifier, you can adjust the Bass Boost circuit. The bass boost is centered at 40 Hz and is continuously variable from 0 to +12dB.


Left Side of Amplifier:

  • +12V (power): set screw terminal; accepts up to 4-gauge wire; the included 3mm Allen wrench is required to tighten/loosen the terminal
  • REM (remote turn-on): set screw terminal; accepts up to 8-gauge wire; the included 3mm Allen wrench is required to tighten/loosen the terminal
  • GND (ground): set screw terminal; accepts up to 4-gauge wire; the included 3mm Allen wrench is required to tighten/loosen the terminal
  • Speaker Outputs: one pair of set screw terminals; accepts up to 8-gauge wire; the included 3mm Allen wrench is required to tighten/loosen the terminals
  • Fuses: three 30-amp ATO fuses (factory installed)

Right Side of Amplifier:

  • RCA Input: one pair of RCA input jacks
  • RCA Output: one pair of RCA input jacks (the amplifier's crossovers have no effect on the line level output signal)


Extended Warranty: Kicker will add a year to the standard two year warranty (for a total of three years) when any matching Kicker amplifier wiring kit is used with this amp (4 gauge minimum). Both the amp and wiring kit should be purchased on the same order and the usual warranty limitations apply (covers manufacturing defects, must be purchased from an authorized Kicker dealer, etc.).

Customer Q&A

1 question already asked

Tony - I've never had the protect light come on in mine. Do you have sufficient area surrounding amp to get good ventilation? Are you trying to drive too big of a speaker? Both of these factors will push the protect light to come on. [ JIMMY  Jan 20, 2014 ]
Yes, my protection light comes on when it hits hard as well. [ SEAN  Jan 19, 2014 ]
mine has never. what is happening is you may be pushing to hard to your sub. your sub should be less powerful then your amp so your amp isnt "overloaded". if this is the case you can bridge it to another amp to split the energy. i have 1 JL 12" sub thats about 800 watts. since this is 1000, it never hits full potential keeping the amp lasting longer. also, your wiring may not be rated high enough for the output. check if the gauge is thick enough. [ CHRISTOPHER J  Jan 19, 2014 ]
I haven't noticed it if it does, [ TYRONE  Jan 19, 2014 ]
light turns on for me if I have the volume cranked. I find it is a pretty good indicator off when you are going" too loud." [ MATTHEW  Jan 19, 2014 ]
