About the Kicker 46CXA400.1T

High-level bass power

Do you like clean bass? Kicker's CXA400.1T mono subwoofer amplifier can put out up to 400 watts RMS, so your bass will both sound loud and full. The quality of the bass tone matters as much as the volume, so a variable low-pass filter helps get maximum performance from your sub/enclosure combination, while a fixed subsonic filter removes the extreme low resonances that cause distortion. A variable bass boost allows you to add some extra low-end punch if you want.  An optional wired remote lets you conveniently adjust the bass level from your front seat.

Hooks in almost anywhere in almost any position

This amplifier works with 1-ohm loads, so you won't have to worry too much about matching impedances when you add a second sub to your system. Kicker's Fail-Safe Integration Technology (FIT™) keeps this amp's input free from noise or interference, so you can tap into your vehicle's speaker wiring for an input signal without a worry. A 3-second turn-on/turn-off delay eliminates system pops and other noises. The CXA400.1T comes with hardware that lets you mount it vertically, so you can put it in a location that takes up very little floor space and looks cool too.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).

CEA-2006 Specifications:

  • Power Output: 150 watts RMS x 1 into 4Ω
  • Signal to Noise Ratio: 75 dBA (measured at 1 watt into 4Ω)

Other Specifications:

  • Power Output:
    • 2Ω: 300 watts RMS x 1 (14.4 volts, ≤1.0% THD+N)
    • 1Ω: 400 watts RMS x 1 (14.4 volts, ≤1.0% THD+N)
  • Signal to Noise Ratio: 95 dB (at rated power output)

Controls:

  • Input Level: 2-position switch; select high (speaker level) or low (line level)
  • Input Gain Control: rotary input Gain control; continuously variable from 250mV to 10V with the input level switch set to low; 1V to 40V with the input level switch set to high
  • Crossover Frequency: continuously variable rotary dial; set the low pass crossover point between 50Hz and 200Hz; the crossover slope is 12 dB/octave
  • KickEQ Bass Boost: increase the bass level between 0dB and +6dB via the rotary control; centered at 40Hz

Subsonic Filter: The amplifier features a non-defeatable 25Hz Subsonic Filter with a 24dB/octave slope. The Subsonic Filter rolls off extremely low frequencies that can't be cleanly reproduced by the amplifier and subwoofers. This reduces distortion and helps the amp run more efficiently.

Mounting: The efficient Class-D Kicker CX Series amplifiers can be mounted vertically, if desired, with the included mounting brackets. When mounted vertically, the dimensions are:

  • Height: 6⅞"
  • Length: 8⅝"
  • Width: 2⅜"

Auto Turn-on: The amplifier has two methods of turning on: +12V and DC Offset. The preferred method is to run an 18-gauge wire from the remote turn-on lead of the source unit to the Remote (REM) terminal on the amp. When a +12V signal is detected on the wire, the amplifier will turn on. If your source unit lacks a remote turn-on lead (a factory head unit, for example), you can choose to turn on the amplifier via the DC Offset method. When a DC offset is detected (>2.5 volts) on the speaker level inputs, the amplifier automatically turns on.

Wire Connections: The CXA400.1 has screw-down terminals for power, ground, turn-on (REM), and speaker output, which will accommodate bare wire or spade connectors. The power and ground slots are 0.512" wide and the remote and speaker slots are 0.335" wide.

External Fuse: The amplifier does not include a built-in fuse, therefore an external fuse should be placed on the power wire, within 18" of the battery. It is recommended that an 8-gauge amplifier wiring kit and a 40A external fuse be used when installing the amplifier.

Note: Currently (as of 4/11/19) Kicker will extend the standard warranty by an additional year (for a total of three years) when a qualifying Kicker Installation Kit is purchased with the amplifier.

Input Signal: The CXA400.1 accepts either high (speaker-level) or low (line-level) input signals on the RCA inputs, selectable using the input level switch on the end of the amp. When using a speaker-level input signal, add the optional Kicker KiSL speaker level to RCA adapter. The input sensitivity is 250mV-10V (low) or 1V-40V (high).

Preamp Output: Using either a speaker-level or line-level input feeds the stereo RCA output, which passes the audio signal to another amplifier or component. This allows you to daisy-chain another amplifier without having to run RCA cables from the head unit to the second amp.

Optional Wired Remote: The optional CXARC remote bass level control can be added to remotely control the output level of the amplifier. The CXARC's control knob can be mounted near the driver's seat, and the control's cable extended to the amplifier location.

Certified Power: Each amplifier is tested when it comes off of the assembly line. Tests are run for Total Harmonic Distortion, Signal-to-Noise Ratio, Protection Circuit, and Total Power Output. A Certified Power certificate with model and serial number is included with each amp with the measured power output figure, and a pass/fail grade for the other tests.

Q
will this amp work with 2 10" kicker 44cwcd104 subs?
[ BRIAN  Sep 22, 2020 ]

A
yes it will. I had it running 2 tens but gave them to my son. I have it running 1 12 inch comp c now. Sounds great.
[ BRIAN  Sep 23, 2020 ]  Staff
A
Absolutely... Depending on what impedence you subwooferes are, this amplifier should be sufficient. Always make sure to match you RMS wattage and impendence when amp shopping.
[ Scott  Sep 22, 2020 ]  Staff
Q
Wired at 1 ohm. What size power and ground wire for this amp? (Approx 15 feet to battery)
[ Dusty  Sep 13, 2020 ]

A
You will need an 8 gauge amplifier wiring kit for the installation of the Kicker 46CXA400.1T amp.
[ Jess  Sep 25, 2020 ]  Staff
A
I'm pretty sure 8 Guage is recommended. It's what I used for mine.
[ Jeremy  Sep 24, 2020 ]  Staff
Q
Will this work with a single Kicker 44CWCD84CompC Series 8" subwoofer with dual 4-ohm voice coils?

Yes, this will work great. It's a great amp.
[ Anh  Jun 18, 2020 ]  Staff
Q
Would this amp be overkill for just ONE JBL Club WS1000 800W 10" Club Series 2 or 4-Ohm Selectable Shallow-Mount Subwoofer in a box?
[ Grimmlock  Apr 26, 2020 ]

I originally purchased an infinity amplifier that I would have assumed would run their REF flex8D subwoofer. With nothing but problems using that amplifier I was able to return it and switched to the Kicker amp to power it. I have been pleased with the results ever since.
[ Brian  May 06, 2020 ]  Staff
A
I think it would be gust fine I always try to over power a bit than I tune it way like it
[ Jubal  May 06, 2020 ]  Staff
A
I don't think so but the Crutchfield Advisor can match everything for you. For a compact and shallow setup in my 06 Wrangler I connected that Kicker 46CXA4001T Amp with a Kicker CompRT 43CWRT81 8" with Dual 1-ohm coils SW that I wired in series and placed in a poly fiber stuffed Pioneer UD-SW200D 8" Enclosure. I did use the EFX Amp 8 gauge wiring kit too. It sounds fantastic. Good luck!
[ Dan  May 06, 2020 ]  Staff
A
I don't believe it would. My set-up is a Kicker 8" sub, 2-Ohm, with an in-line control knob. Sounds great
[ ISAAC  May 06, 2020 ]  Staff
A
you could use it, just turn it down If to much
[ Borden  May 06, 2020 ]  Staff
A
No, I have a Jeep Wrangler I used this in with a shallow mount sub. It worked perfect and sounds great.
[ JASON  May 06, 2020 ]  Staff
A
No I'm running two 8inch Pioneer subs on it and 150 W apiece works just fine get the base Knob
[ Ernest  May 06, 2020 ]  Staff
A
That amp would be a perfect match for that subwoofer at 2 ohms.
[ Roger Kyle  May 06, 2020 ]  Staff
A
I don't believe so

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.
[ Krissy  May 05, 2020 ]  Staff
Q
Would. A kicker Amp.246cxA40000 1T. Push or pound 2-8" kicker subs 44cwcs84 .?
[ Antdogg  Jan 28, 2020 ]

[ IAN  Jan 28, 2020 ]  Staff
A
I think it would have no problem. I'm running a single 10" alpine type S sub and it hits this sub nicely.
[ Brett  Jan 28, 2020 ]  Staff
A
YES!
[ JEFFREY D  Jan 28, 2020 ]  Staff
A
It would be a good matching combination. The amp is stable to 1 ohm, so If you wire the speakers in parallel to achieve a combined 1ohm resistance the amp rms and the speakers rms are equal. Should work great.
[ LUKE  Jan 28, 2020 ]  Staff
A
Yes
[ Jason  Jan 28, 2020 ]  Staff
A
Its should push good if you get 2 4ohm subs. You can expect a total output of 300w (150 each) and Kicker usually exceeds the rated power output.
[ Philip  Jan 28, 2020 ]  Staff
A
It would be more than enough. Mine is pushing (2) 12" and sounds awesome. Small but mighty this one is..
[ Anh  Jan 28, 2020 ]  Staff
A
I have mine hooked to two 12 " kickers in the cab of a 3/4 ton full size extra cab truck and the are amazing. I have the adjustable dial sold by cruthfield well worth the money.
