Power for your bass

Leave it to Kicker to come up with a great way to get strong bass in your ride. Their CX300.1 amplifier delivers up to 300 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 CX300.1 also comes with hardware that lets you mount it vertically, so it'll take up very little floor space and look ultra-cool.

Putting together a bass system with this amp? Check out these Crutchfield-approved 150-watt and 300-watt bass packages.

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.

Great Bang For Your Buck!

Written By JasonM, SO. ILL. on Friday, April 24, 2015

Crutchfield Customer Review (What's this?)

You will look long and hard for a amplifier with this kind of power for the price. I am running this amp at 2ohms to a single HELIX 10" sub in my GMC crew cab and it is amazing the amount of bass being produced. I have owned many brands of amps over the years and this one is up at the top of the list. Also kicker tests its amps before they ship and you get a factory power output slip with each. Mine came in at 318.


Cons: I have not one complaint about this product.

Top of the line amp

Written By Jon, Texas on Tuesday, April 14, 2015

Crutchfield Customer Review (What's this?)

I pared the amp with a JL Audio CS110LG-TW3 Single 10 inch sub woofer in a 85 Chevy C10 truck . The recommended RMS watts for the sub woofer was 100-400 watts. With the brand Kicker they will always exceed the watts of their amps, so instead a 300 watts I received amp that delivered 346 watts RMS. Being the first amp I have ever bought kicker is now my go to amp brand. The amount of POWER coming from this little amp was flawless and gave plenty of power to the Sub Woofer. I will be keeping this system for a long time in my truck.

Pros: Quality Sound Power Customer Service Size Design

Cons: None

Dont be fooled by the size!

Written By Kyle, New York on Saturday, March 21, 2015

Crutchfield Customer Review (What's this?)

GREAT Mono amp! Awesome compact size fits anyplace, mounts any direction and simple controls. Great look can go with any interior style, but so small you'll never see it. Pushes hard and stays clear. I bought a second for my other truck!

Pros: Small yet powerful!

Cons: NONE.

300.1 amp

Written By Scott, Florida on Wednesday, January 28, 2015

Crutchfield Customer Review (What's this?)

I love the size of this amp!! Very small footprint, came with a certified power output from Kicker, tested and passed at 310watts RMS. I love this about Kicker! I have had it for about a week and it pushes my enclosed comp s 10 perfectly! So far, so good. Thank you Crutchfield, for carrying a great amp from a great company!

Pros: Small footprint, and even though I didn't use it, the vertical mounting bracket is a nice touch.

Cons: Would have liked to see a 40 amp fuse built in, just for extra security.

Great liittle Amp

Written By Brian, Island Heights, nj on Monday, December 29, 2014

Crutchfield Customer Review (What's this?)

I am using this to drive a Sony XS-GS80L subwoofer. This is a great little amp. It is small yet puts out plenty of power. It is also very adjustable to get the sound you want out of it, The control buttons need accessibility and if you plan on mounting the unit somewhere difficult to reach, I would recomment the remote. I was concerned about mounting it on a crapet floor due to heat so may a thing platform out of HDPE. Not sure if it was necessary but...

Pros: It is unit is small and can be placed anywhere due to its sze. It comes with brackets to mount off a wall. It has a good clean sound.

Cons: Cannot be mounted upside down (Such as under something). It appears the fin orientation is important for cooling it the manufacturer always wants teh unit laying flat. Although there is no mention of mounting flat to a side wall, they provide brackets to reorientate the unit flat even when mounted to a side wall.

'08 350-Z Install

Written By Sunnfunnc, North Carolina on Sunday, November 02, 2014

Crutchfield Customer Review (What's this?)

If you need more crisp, clean bass than this amp provides (coupled with a Kicker 40CWD104 subwoofer) for a 350-Z, you are going to have serious loss of hearing at a very young age. . . . I SAID IF YOU NEED MORE CRISP, CLEAN BASS . . . . I think you hear me now.

Pros: More than enough bass without being obnoxious, good value

Cons: No installation instructions for non-professional installers

Very Impressive

Written By FM Steve, Flower Mound, TX on Tuesday, September 02, 2014

Crutchfield Customer Review (What's this?)

I was impressed with this amp the second I opened the box. The amp's birth certificate said it bench tested at 337 watts when it was rated at 300. Stuff from China won't do that. All the necessary mounting hardware and instructions were included for a pain free installation. I'm driving two 10" Kicker subs with this amp and it rocks. I couldn't be happier with my combination. Thanks for recommendations Crutchfield, I trust you with my future audio needs hands down. Cheers!

The BIGGEST 300 watts I've ever heard!

Written By Terry, Marquette Heights, Illinois on Monday, July 15, 2013

I'm in my mid 30's and have been doing high powered car audio for a long time. In the past, I've done the multi-amp systems and pushed over 1200 watts. However, in my 2002 Mustang GT that I race, I wanted less weight. I just put this amp in because it was small, light and cheap. This thing HAMMERS! This is the biggest bang for the buck that I've ever gotten in car audio. I'd easily put it up against most other brands' supposed 500 watt amps.

Pros: Small, lightweight, extremely efficient, very affordable

Cons: Absolutely nothing!

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
  • 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): terminal strip; accepts spade connectors up to 0.5" wide
  • REM (remote turn-on): terminal strip; accepts spade connectors up to 0.325" wide
  • GND (ground): terminal strip; accepts spade connectors up to 0.5" wide
  • Speaker Outputs: terminal strip with two pair of subwoofer outputs; the two outputs are internally shorted together, making it easy to wire two subwoofers; accept spade connectors up to 0.325" wide
Note: The Amplifier is not equipped with an internal fuse. An external 40-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 40-amps, the original should be replaced with a 40-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 an 8-gauge wiring kit with this amplifier.
