Power for your bass

Leave it to Kicker to come up with this bantam heavyweight. The CX600.1 amplifier delivers up to 600 watts RMS to your subwoofer from a 7" x 8" chassis that'll fit almost anywhere. And they don't cut any corners building this amp, using oversized transistors, special transformers, and a heavy-duty heat sink to bring you awesome power that won't fade when you push your system hard.

Control over your bass

Kicker includes a low-pass filter to keep high frequencies away from your sub, a fixed subsonic filter that protects your sub from inaudible, power-devouring ultra-low frequencies, and a variable bass boost that allows you to add some kick to the mix. An optional wired remote bass level controller is available so you can crank the bass up or down from the front seat.

Vertical mounting

Includes hardware for vertical mounting

Hooks in almost anywhere in almost any position

Kicker uses their Fail-Safe Integration Technology (FIT™) to keep this amp's input free from noise or interference, so you'll get a clean signal from almost any system, even a factory radio. Rugged metal end panels provide even more shielding from radiated interference. The CX600.1 also comes with hardware that lets you mount it vertically, so it'll take up very little floor space and look ultra-cool.

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.

Written By Rorge, Indiana on Monday, October 19, 2015

Crutchfield Customer Review (What's this?)

I went with this amp for two reasons. 1. Compact, 600+ watts in a small package. 2. Price, under $200. I am satisfied with it, but don't expect too much, You get what you pay for.

Pros: Size, price

Cons: Not a top of the line amp.

Love it!

Written By John P., New Jersey on Sunday, October 04, 2015

Crutchfield Customer Review (What's this?)

I love this amp. I bought this after attempting to buy used equipment on craigslist, and nothing worked out. I have had it for about a month now. This amp has a great warranty. It is small, powerful, and sexy. Easy to set up using 4 gauge power wire. Used a DMM to tune the gain, and it stays put perfectly. This combined with 2 12" kicker subs is amazing! My rear view mirror is useless now, it just gets shaken down within seconds LOL. Great quality sound, great bass, great everything. For sure recommend this amp.

Pros: Small, powerful, sexy, upright mounting, warranty.

Cons: None at all.

Perfect Amp

Written By Adolfo B, Maryland on Tuesday, July 21, 2015

Crutchfield Customer Review (What's this?)

When this amp arrived, I was surprised to see how small it actually was. But it has a lot of power! I matched this amp with Kicker's dual 10 inch CompS subs and together they work perfectly. I couldn't be happier with this amp. I attached it to the top of my sub right next to my 4-channel amp. This amp was easy for me to install (partially because I already had an amp in my trunk) and did not heat up very much after an hour of use or so in the beginning of July.

Pros: size excellent build quality plenty of power does not overheat easily

Crutchfield Customer Review (What's this?)

This is a high quality, user friendly, dependable amp with heavy duty connection posts. This amp is small in size, but big in power so it's ideal for areas with little room to work with. I always feel confident when purchasing kicker products because they stand tough when put to the test, Very nice amp that's well worth the money.

Pros: The amp comes with an instruction manual and an Allen key wrench for making your connections

Cons: None

Big Power--Small Package

Written By J_tosti, Indiana on Wednesday, December 17, 2014

Crutchfield Customer Review (What's this?)

To be honest, I had some reservations regarding Kicker's CX line of amplifiers. However, after having experiences with two (2) of their models, I must say I am very impressed with the quality, design, and performance of this product. Regarding power: This amplifier is advertised as producing 600 watts x 1 at 2 ohms. Upon delivery, the final product quality certificate confirms that this power is achieved plus some. Regarding features: Nothing really special. You will find typical features such as gain, frequency, bass boost, and hi/lo pass; however, for the type of amplifier this is, I wouldn't expect much more. Amplifier adjustments are simple and directions are intuitive. Very nice amplifier at a nice price point.

Pros: Powerful, Efficient, Small Footprint, Option for remote bass control available.

Cons: None at this time.

this app is awesome I have it pushin a 1 12" Kicker comp R it is wild it sounds amazing I really think that it's pushing more than 600 watts I would highly recommend any kind of kicker amp to any of my friends or family

Pros: the pros of this app is at its compact holds a lot of power and I don't get hot easily and its just a good all around

Cons: honestly I don't have no cons I have no complaints about the dimensions: nothing this this technology is just superior

Tiny size with huge power!

Written By MavericksDad, Elk Grove ca on Monday, September 08, 2014

Crutchfield Customer Review (What's this?)

This amp was recommended by my Crutchfield technician, and I must say I was alittle skeptical that an amp rated at this output and at this cost could really be as good as advertised. Well let me say I am extremely happy with the clean, crisp lows this amp is providing my 2 12in JL W0's. The footprint is tiny and can be mounted dang near anywhere I wanted. Does not get that hot either! Overall bang for the buck?? 10/10

Pros: Plenty of wattage, small size, ease of adjustments

Cons: None

Crutchfield Customer Review (What's this?)

This amp brings out all the bass needed for both my 10" JL subs. The bass is so clean and clear. This amp has the option for me to install a volume knob. When i have people in the car I bring it down or just all the way down so it doesnt bother people. I love that. The amp itself is so small and I can fit it just about anywhere i like. I love it. Worth every penny.

Pros: Size, quality, clean bass

Cons: None

Very surprised of the size of the unit itself. I installed it in my nephews car and with the small footprint I was able to put it pretty much any place. Its got great power and easy to setup. Would recommend this item especially if you are limited on space like a single cab truck or lacking trunk space.

Pros: small, easy to setup, clean power

Cons: none so far

  • "Coolness Factor"
  • Build Quality
  • Ease of Use
  • Sound Quality
  • Value

This amp is great as far as size and power. I purchased it to install in my 2003 wrangler. This amp has brackets that allow you to install standing up on its side which is perfect because I selected the space inside the center console where the factory amp and sub lived prior to upgrade. The amp is pushing two SVC 4 ohm kicker subs that I ran in parallel for a 2 ohm load and the amp is perfectly suited. I ran 4 gauge wire for power and ground so the amp gets all the power it needs and did not get hot at all during the tuning process. The jeeps like mine that were equipped with factory sub and amp have a slotted hole where the sub fired out that also should help keep the amp cool.

Pros: Size is great, power is awesome, and the ability to mount standing on its side makes more install options possible. Not to mention the competitive pricing and kicker quality.

Cons: None yet

Crutchfield Customer Review (What's this?)

This is my first Class D amp. I am pushing two Kicker 10" DVC's, with them set to 1 ohm resistance and wired in serial to the amp. It is such an improvement from my last amp, which was rated at 850 Watts RMS. Well worth the price for this amp if you want to hear clean, powerful bass.

Pros: Lots of Power. Small Footprint. Easy to set up.

Cons: None that I have found.

very good affordable product great value

Written By bryanplez, Denver, CO on Tuesday, April 15, 2014

I got this amp to replace a blown jbl amp. It's powering two Boston G2 10s in a custom box. And gives all the power i need! Installed in a BMW 323I E46, absolutely pushes these high quality subs perfectly!! Great amp for the price. Easy to install,and also running a avh-x7500bt, and they compliment each other great!

Pros: Price,dependability,power, ease of install, i like the fact you do not need a LOC if you want to use the amp with a factory radio. The yellow line is a great value from Kicker!!!

Cons: Not many cons at all with this Amp after 3 months of being used. May have some complaints in the future. I will just have to wait and see.

Big boom for the buck

Written By ptk61, Skiatook, OK on Thursday, December 26, 2013

Crutchfield Customer Review (What's this?)

This was my first foray into installing a power/sub amp in a vehicle, so I'm writing this from the perspective of someone who felt his way through the install. To someone new to car amp installs I would offer this advice: buy the Kicker PK4 wiring kit to go with the amp if you don't know what size wire or what the amperage of the fuse should be. There are plenty of good vids on a Kicker amp install, please watch at least one comprehensive one before starting out on your install if you are new to this.

I bolted the amp to the passenger seat back in my '07 Corvette and ran the cables along the passenger door panel. The amp is connected to a Polk Audio DXi104 10" subwoofer and even at low power the amp will really move the speaker. It sounds great and provides the bottom end depth that the miserable 2 ohm factory mid-bass units in the doors lack (and which are nearly impossible to replace). Although I'm impressed, this is the first car sub amp I've ever owned so I have nothing to compare it to.

Pros: plenty of power, multiple mount options

Cons: The volume and adjustment knobs on the amp don't have a detent you can put a screwdriver in so you can adjust them easily. I don't care for the mash-down connectors for amp power/ground/speaker outs.

The kicker cx 600.1 amplifier is by far the best for the money and it puts out what it says it will. Great investment.

Hands-on research

What's in the box?

Download owner's manual

  • Mono subwoofer amplifier
  • 2 Vertical mounting brackets
  • Four 3/4" Self-tapping screws
  • 3mm Allen wrench
  • Owner's manual (English/ Spanish/ German/ French)
  • Power certification sheet

Product Research



Gain: The rotary gain control is continuously variable from 125 mV to 5 V when the Input Sensitivity switch is set to Low and 250 mV to 10 V when the Input Sensitivity switch is set to High.

Input Level Switch: Set the input level switch to Lo when using a preamp level input signal and Hi when using a speaker level input signal.

Crossover: The crossover is always engaged (cannot be bypassed). The crossover point is continuously variable from 50 to 200 Hz and the slope is 12 dB per octave.

Subsonic Filter: The subsonic filter is fixed at 25 Hz and 24 dB per octave.

Auto Turn-on: The amp offers two automatic turn-on modes:

  • +12V: connect a wire from the remote turn-on lead from your source unit to the REM terminal on the amplifier; this is the preferred turn-on method
  • DC Offset: turns the amp on when a 6-volt DC offset is detected at the high-level speaker inputs when the source unit is turned on

Bass Boost: The bass boost circuit is continuously variable from 0 to +12 dB and centered at 40 Hz.

CXRC Remote Bass Control: The bass output level can be controlled remotely using an optional wired remote bass control (item number 20612CXRC, sold separately).

Vertical Mounting: The amp can be mounted vertically using the included brackets. The vertical dimensions are approximately:

  • Width: 9"
  • Height: 7-1/4"
  • Depth: 2-3/8"

Signal to Noise Ratio: The S/N under CEA-2006 compliant conditions (1 watt output) is 75 dBA. The S/N at rated power is 95 dB.


Left Side of Amplifier:

  • +12V (power): set screw terminal; will accept bare wire up to 4-gauge
  • REM (remote turn-on): set screw terminal; will accept bare wire up to 8-gauge
  • GND (ground): set screw terminal; will accept bare wire up to 4-gauge
  • Speaker Outputs: terminal strip with two pair of subwoofer outputs; the two outputs are internally shorted together, making it easy to wire two subwoofers; accepts spade connectors up to 0.325" wide
Note: The Amplifier is not equipped with an internal fuse. An external 80-amp fuse (not included) must be installed on the power wire. If the system has only this amp and a wiring kit is used that includes a fuse with a value other than 80-amps, the original should be replaced with an 80-amp fuse.

Right Side of Amplifier:

  • RCA Input: one pair of stereo RCA input jacks; also used for speaker level input (item number 206KiSL needed, sold separately)
  • RCA Output: one pair of stereo RCA output jacks; line level output when using either preamp or speaker level inputs
  • Remote Bass: 3.5mm mini-jack for use with the optional CXRC wired remote bass level control

Amp Wiring Kit: Kicker recommends using a 4-gauge wiring kit with this amplifier.
