Our take on the Kicker 12CX300.1

by Buck Pomerantz
Kicker

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.

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.

Features

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.

Connections

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.

Just what I needed

Written By Julio, Danvile, KY on Friday, November 15, 2013
Crutchfield Customer Review (What's this?)
 
I purchased this amp in order to replace what Nissan and Bose considered to be an amp that came standard with my Nissan 350Z 345th Anniversary edition. It was easy to install and it fit perfectly in the globe compartment of my Z. I wired a Kicker 40CWD104 subwoofer that truely enhanced the sound of my car. Very easy to use as well.
Pros:
Easy to use and instal
Cons:
None.

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!

Great amp

Written By Noel R, Hawaii on Saturday, July 06, 2013
Crutchfield Customer Review (What's this?)
 
I was a looking for a simple amp that allowed for a high freq connection without a crossover. In the end, I didn't even use that set up. Amp matched perfectly with my sub.
Pros:
A lot of flexibility with the setting to get the sound you want.
Cons:
None that I can think of.

  • 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.

1 answer
  • I forwarded your question to an Advisor and they responded with the following: From the information we are provided and looking at the owner?s manual it looks as if you will need a remote bass controller for each amplifier individually.
