Our take on the Kicker 08ZX300.1

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.

If you're into cruising to great music, Kicker's powerhouse ZX Series amplifiers offer exceptional sound quality, along with distinctive, no-frills good looks.

The Kicker 08ZX300.1 mono subwoofer amp will drive your subs with up to 300 watts of power — enough to give you the big bass sound you want. Kicker's ratings reflects a true measure of the amp's power capabilities — no inflated "peak power" ratings here. Efficient heat sinks and rugged internal components ensure reliable operation and clean power output, even when you crank your system hard for long periods of time.

Switch on the built-in low-pass filter to send everything below 80 Hz to your subwoofer, while the subsonic filter removes the extreme low frequencies that hamper system efficiency. You can kick in more low-end bump with the bass boost, and the included wired remote control lets you turn on the boost from the driver's seat.

Features

CEA 2006 Compliant: The ZX300.1's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.

Kicker "Livin' Loud" Certified Power Certificate: The amplifier comes with a certificate that indicates the total maximum wattage of the particular amplifier, along with the model number, serial number, tested date, and whether the amplifier passed the total harmonic distortion, signal-to-noise ratio, and protection circuit tests.

Dual Input Sensitivity Differential RCA Inputs: The ZX300.1 has one pair of RCA inputs which will receive either high or low level signals from your car stereo. The unit has an input level switch that allows you to select a low- or high-level input. A low-level signal from the stereo's preamp output is recommended. If the stereo lacks preamp outputs, you can use the unit's speaker-level outputs by splicing RCA plugs onto the speaker wire or using an RCA-to-Speaker wire adapter (136CLR2SW, sold separately) , and setting the input level switch to "HI".

Auto Turn-on Selection: The ZX-series offers three different automatic turn-on modes that can be selected on the end panel. You can select from the following modes:

  • Remote Turn-on: You can connect an 18-gauge 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 Turn-on: The DC offset mode detects a 6-volt surge from the high-level speaker outputs when the source unit is turned on. If remote turn-on is not an option, this is the next best choice.
  • Signal Sense Turn-on: This method detects the incoming audio signal from your source unit and automatically turns on the amp. This method will not work properly if the input gain control is not set properly.

Protection Circuitry: The ZX300.1's protection circuitry guards against accidents and undesired operation. The amp is protected by thermal protection, voltage protection, and short circuit protection. The Power LED on the left side of the amp glows green and the power indicator on top of the amp glows red when the amplifier is connected correctly and the protection has not been engaged. If the red Protection LED illuminates, the amp's protection circuit has been engaged and the amplifier is in protect mode until the problem is resolved.

Optional ZX-Series End Caps: You can add the optional ZX-series amplifier end caps (2068ZXEC, sold separately) to this amplifier. These plastic end caps cover the wire terminals and controls located on the ends of the amp for a clean installation. When installed, the end caps add approximately 2-5/8" to the overall width of the amplifier.

Controls

Low-pass Filter: The internal low-pass filter, fixed at 80 Hz, can be switched on or off as needed. The filter has a slope of 24dB per octave.

Subsonic Filter: The subsonic filter allows the amplifier to block ultra-low frequencies that your subs can't reproduce, improving the efficiency of your speaker system. The filter is fixed at 25 Hz, and has a slope of 24dB per octave.

KICKEQ Bass Boost: The ZX300.1's KICKEQ bass boost circuit provides a +12dB signal boost at 40Hz. The bass boost can be switched on or off as needed.

Remote Bass Level Control: The Remote Bass Level Control lets you adjust the output level of the amplifier from anywhere in the vehicle. When attached to the mounting bracket, the Remote Bass Level Control has the following dimensions: W=2.207", H=1.175", D=2.133" (including the knob). A 19' 9" cable is included for routing the remote bass level control signal to the front of the vehicle.

Connections

Left Side of Amplifier:

  • +12V (power): gold-plated set screw terminal (accepts up to 4 gauge wire)
  • REM (remote turn-on): gold-plated set screw terminal (accepts up to 8 gauge wire)

Kicker ZX300.1

Written By Reagan, College Station, TX on Sunday, April 18, 2010
 
All the rave reviews about it got me thinking. I have it wired at 2 ohms to push two 12" RF Punch stage 1 subs, and it hits way harder and much more crisp than my old Sony amp, even though it's used!! The settings are conveniently located, especially since its mounted behind the seat in my truck. A previous reviewer said he took 30 minutes to get the sound he was looking for. It took me about 30 seconds just because it was so easy to find the perfect setting!

Pros: excellent sound, especially for a 300W amp. Crisp, clear, and loud.
Cons: absolutely none.

Powerful

Written By no, NYC on Sunday, October 25, 2009
 
This amp has multiple turn on features. Which is good since I kept the factory
radio. My amp exceeded specs listed on the box, it rated at 346 when tested. The
amp runs cool. To bad it is not as small as the Rockford in the same range. This
amp is one of the few that can still use 8 gauge power wires and put out this
much power.

Crutchfield Customer Review (What's this?)
 
I used to own a 600 watt Kenwood amplifier that was hooked up to my Kicker comp vr subwoofer it got me threw with what i wanted but also distorted the sound a lot! then one day it somehow got wet from inside of my trunk. it continued to work after that but then the fuse broke. i tryed replacing it with many types of blade fuses, no success. so it was time to get a new amplifier. after looking around at various other amplifiers this was the one i decided on. i always knew kicker was one of the best it cost the same as my Kenwood and was labeled under kicker. i was hesitating about the maximum power wattage in this amp for it said 300 watts max power. i went ahead and bought it and boy was i wrong! this amp packs a huge punch! it is louder than my old amp, perfect on pitch sound with no distortions, and very cheap :D i would diffidently recommend this amp to anyone!

Kicker 08ZX300.1

Written By Anonymous, Prattville, AL on Sunday, January 25, 2009
 
I just bought a 10" kicker L5 Solo Baric enclosure for my 98 firebird
hatchback. And paired it with this amp the sound is incredible it produces
enough bass to satisfy your want for that extra thump, while still keeping a
good articulate sound you get more than your moneys worth.

Fine Amp

Written By Tracy, Minneapolis, MN on Sunday, November 30, 2008
 
I have this powering a single, 8-inch, 4-ohm, single-voice-coil subwoofer. I later learned that mono amps are best when powering two subs wired together to present a 2-ohm load, so I may not be using this amp to its full potential. It seems to be doing just fine though for the way I am using it.

Pros: rock solid piece of equipment, very reliable, easily powers my sub, and plays my music as loud as I want it to

Cons: it has my biggest pet peeve of any amp... that is, it has an annoying "pop," a loud sound heard through the speaker, when it turns on. I hate it when an amp does this! You'd think that with being amps as good as they are this day and age that this is something they could get rid of once and for all, but--sigh--this amp has the "pop."

Top of the line--no question.

Written By Robert, Garner, NC on Monday, May 26, 2008
 
I purchased this gem of an amp to push a Kicker 10C sub in my 1996 Dodge
Dakota pickup truck. I custom built a 1'2" plywood box, sealed it with
fiberglass resin and mounted it to the backwall on a double layer of
dynamat and two coats of herculiner.

Once I hooked up this amp, and powered up the stereo--i was amazed at
the crisp clean low sound. I have always utilized 8" Kicker Solobarics--and
was kind of antsy about using a new sub--but once I paired it with this
amp--there was no question I made the right decision.

This amp rocks. I would suggest to take your time on initial setup and play
with the crossovers, ranges, etc. and be sure you have it right for your
vehicle. I spent about 30 minutes doing this--and definitely made the right
decision.

Buy this amp--and you will definitely not regret it.
