About the Kicker 43CXA1200.1

Mega-power for your bass

Looking for massive bass? Kicker's CXA1200.1 mono amp can send up to 1,200 watts RMS to your subwoofer. But brute force isn't everything with this CX Series amp — you can use the variable low-pass filter to get maximum performance from your sub/enclosure combo, while the fixed subsonic filter removes the extreme low resonances that cause distortion. The variable bass boost allows you to add some low-end punch if you need it (but you probably won't).  An optional wired remote lets you conveniently adjust the bass level from your front seat.

Hooks in almost anywhere in almost any position

Kicker's Fail-Safe Integration Technology (FIT™) keeps this amp's inputs free from noise or interference, so you can tap into your speaker wires for a signal without a worry. The CXA1200.1 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.

Note: This amplifier can draw some serious amounts of current (up to 108 amps), so you may have to upgrade the electrical system in some vehicles to power it effectively.

Perfectly matched AMP, with the help of a Crutchfield tech. Thank you Crutchfield for taking the time to help me pick out the perfect components for my Son's first Car. He is a United States Marine. We wanted to set up his vehicle super special since we do not get to see him very often. When his car was delivered he was blown away with the system we had installed for him. Thanks again!!!!!

Pros: Matched perfectly with speakers. Packed with great features. Cross over and boost were super easy to set up.

Cons: NONE!

Awesome amplifier

Angel from Dallas, TX on 3/1/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This amp is by far everything I need to power my two Kicker 43CWR122's (wired in series parallel to get 2 ohms). I had the Kicker 43CXA600.1 amp connected but it was not enough juice to get the clear bass I was looking for. This larger amp gives them the power they need to hit super solid!! Has this current set up in my 2011 Honda Civic and it sounds awesome! No capacitor needed to feed this beast, just a quality 4 gauge Kicker amp wiring kit that also extends the amps warranty by an additional year. I'm running this system with a Pioneer AVH-X5700BHS head unit. I'm don't even have the gain is only half way up and it sounds fully powered. I can go on and on about the amp for hours about how great the quality and for the price isn't bad. If you're thinking about this amp do yourself a favor and buy it!! I have the bass level adjustment knob on the way so that I can stop the bass in a second when I see the police. I don't need another citation for disturbing the peace, because this setup BOOMS!

Pros: Easy installation, great quality product, Crutchfield support

Cons: None

Great amp pulls alot of power

Jon from Charlottesville, VA on 8/29/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

Great amp. Pulls a large amount of power from the auto. Make sure you have a large cap and upgrade your alternator wire, or it will clip as it can't pull the amps it needs. Mine is hooked up to 1 15 4dvc wired 2ohm mtx 9500. Mine is dynoed at 1276watts.

Pros: Plenty of true rms power Doesn't get hot Price

Cons: Pulls alot of power from the auto. Electrical upgrades are needed if clipping is present

This amp is pretty awesome. I have 6,12s and 3, 10's hooked up to it and the gain is only at 3.5 ,bass boost at half,and it really pushes the subs and slams hard. I bought 2 of them from best buy and the second one is not even hooked up

Pros: Puts out a real 1200 watts,I had it dynoed

Cons: None yet

This amp is awesome. There is so much power I have to upgrade my 2 10" Infinitys because it keeps clipping. Very easy set up.

Pros: Small and compact and does not get hot due to the class D amplifier.

Cons: If anything too much power, but that is not a problem!

Product Research

Features

Overview: Kicker CX Series amplifiers can deliver plenty of power when you need it, utilizing high-grade internal components and an optimized circuit layout. This Class D amp has highly efficient heat sinks to keep the amp running cool. You can mount the amplifier vertically, if desired, with the supplied mounting brackets.

Power Output: The CXA1200.1 is a mono amplifier designed to output 600 watts RMS at 4Ω (<1% THD+N @ 14.4V) and 1200 watts RMS at 2Ω.

Controls: The controls for the amplifier are located on the side of the amplifier:

  • Input Gain Control: The rotary input Gain control lets you match the output of the source unit to the amplifier. When setting the Gain, you should turn the source unit up to about 3/4 of the maximum volume, adjust the gain until audible distortion can be heard, then back the gain down slightly. The Gain control goes from 0 to 11.
  • Low Pass Filter: You can select a crossover frequency between 50Hz and 200Hz. This adjusts the upper frequency limit of the amplifier's output. The rotary control can be adjusted with a small slotted screwdriver (not included).
  • Input Level: The RCA inputs on the amplifier will accept a high-level or low-level input. Using the Input Level switch, you can select high level (button in) or low level (button out) input.
  • KickEQ Bass Boost: The bass level can be increased between 0dB and +12dB via the rotary KickEQ Bass Boost control. The bass boost circuit is centered at 40Hz.

Subsonic Filter: The amplifier features a non-defeatable 25Hz Subsonic Filter with a 24dB per 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.

Auto Turn-on: The amplifier has two Auto Turn-on modes: +12V and DC Offset. The preferred auto turn-on 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 6V DC offset is detected on the source unit's speaker outputs, the amplifier automatically turns on.

Connections: The CXA1200.1 has set screw terminals for power, ground, and turn-on lead (REM). The power and ground terminals will accept up to 4 gauge wire (recommended), and the turn-on lead will accept up to 10 gauge (18-gauge recommended). The set screws can be loosened/tightened with the supplied 3mm Allen wrench. The speaker outputs are slotted, screw-down terminals, which will accommodate bare wire or spade connectors. The speaker slots are 5/16" in width, and will accommodate up to 10 gauge wire.

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 a 4-gauge amplifier wiring kit and a 150A external fuse be used when installing the amplifier.

Note: 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 CXA1200.1 is capable of receiving either high- or low-level input signals, and you can select the input type on the end of the amp. A pair of female RCA jacks is provided on the end of the amp. If you are using a speaker-level source, you can use the optional Kicker KiSL speaker level to RCA adapter. The Input Sensitivity is 250mV-10.0V (High Level), while the Low Level Input Sensitivity is 125mV-5.0V.

Preamp Output: The CXA1200.1 has a 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. Either input method, high- or low-level, will provide a low-level output signal at the RCA output.

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
I purchased the 15in kicker comp and this amp. The kicker 1200 watt 2 channel amp. But it's just not pushing the subs very well. I feel like there is a different way I can wire it to get best performance. But on crutchfield sure it days N/A for bridging amp but it days amp can do 600 watt at 4 ohm. An 1200 watt at 2ohm both by 2. So my question is how do I wire it to get 1200 at 2 ohm ? And. Can I safely bridge this amp?
[ Kimberly  Dec 16, 2016 ]
1 answer
A
This amp is a mono (single channel) model so it cannot be bridged. The two sets of terminals are provided to make it easier to connect multiple woofers but they are wired in parallel inside the amplifier. The basic Kicker "comp" models are single voice coil so, if you have a single 4 Ohm model, you will not be able to present the final 2 Ohm load to the amp without adding a second 4 Ohm 15" comp wired in parallel: http://images.crutchfieldonline.com/ca/learningcenter/car/subwoofer_wiring/2SVC_4-ohm_mono.jpg I hope that helps.
