Our take on the Kicker 10ZX700.5

by Buck Pomerantz

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 appreciate the difference between great sound and just blowing a lot of air, then you'll really like the way Kicker ZX amps play your music. This ZX Series 10ZX700.5 5-channel amp employs a low-distortion Class AB design that'll power your front and rear speakers, along with a highly efficient Class D subwoofer section. You'll enjoy thrilling details, plenty of bass power, and newfound clarity from your vehicle's entire speaker system.

Power your entire system
Of course, this Kicker can play loud if you want, pumping 70 watts RMS to each of your front and rear speakers, as the dedicated subwoofer channel puts out up to 420 watts RMS of clean bass power. This versatile amp will power your entire sound system, filling your listening space with the clean power you need to overcome road noise and grab your passengers' attention. You can also switch the 4-channel section over to 2-channel mode, and drive your front speakers with a slammin' 165 watts each. The high-pass, low-pass, and subsonic filters, along with the variable bass boost, allow you to get the best possible performance for your car and your system.

Extended warranty
Balanced differential inputs help prevent noise from entering your system, and also allow you to wire ZX amps to almost any receiver. This ZX amp is so dependable that Kicker normally warranties it for two years, but they'll extend that warranty to three years if you purchase the appropriate Kicker amp wiring kit with it.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.



CEA 2006 Compliant: The ZX700.5's power and signal to noise ratio ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the output ratings of all CEA 2006-compliant amplifiers, even from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The manual lists three signal to noise ratios:

  • CEA 2006 compliant:
    • Full Range Channels: 92dB (ref: 1W, A-weighted)
    • Subwoofer Channel: 62dB (ref: 1W, A-weighted)
  • At rated Power: >95dB (A-weighted) for both full range and sub channels

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.

Five Channel Design: The amp is divided into three sections, essentially two 2-channel amps and one mono amp in one chassis; Amp1, Amp2, and Sub. The hybrid design uses Class AB for Amp1 and Amp2, and Class D for the subwoofer amp. The three sections have independent inputs, gain controls, and crossover controls. The rated power output is as follows (measured at 14.4 volts with <1% THD+N):

  • Amp1 and Amp2:
    • 4Ω Stereo: 70 watts x 4
    • 2Ω Stereo: 85 watts x 4
    • 4Ω Bridged: 165 watts x 2
  • Sub Amp:
    • 4Ω Mono: 210 watts x 1
    • 2Ω Mono: 420 watts x 1

Dual Input Sensitivity Differential RCA Inputs: The ZX700.5 has three pair of RCA inputs that will accept either high or low level signals. The unit has an input level switch that allows you to select a low- or high-level input; low-level signals from the stereo's preamp outputs are recommended. If the stereo lacks preamp outputs, you can use the unit's speaker-level outputs; attach RCA plugs to the speaker wires (adapter item number 136XDCLR2S) and set the input level switch to HI (one switch controls Amp1, Amp2, and Sub inputs).

Auto Turn-on Selection: The ZX-series offers three different automatic turn-on modes; select from:

  • Remote Turn-on: 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 Turn-on: the DC offset mode detects a 6-volt DC offset 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; the REM terminal will have +12V out for turning on an additional amplifier
  • Signal Sense Turn-on: detects the incoming audio signal from your source unit and automatically turns the amp on; will not work if the input gain control is not set properly; the REM terminal will have +12V out for turning on an additional amplifier

Protection Circuitry: The ZX700.5's protection circuitry guards against damage and undesired operation. The amp is protected by thermal protection, voltage protection, and short circuit protection. 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.


Crossovers: The internal crossovers for Amp1 and Amp2 are set independently to high-pass or turned off (full range). The crossover points are continuously variable from 50 to 200 Hz and the slopes are 12dB per octave. The subwoofer crossover is always engaged; its crossover point is continuously variable from 50 to 200 Hz and the slope is 24dB per octave.

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

Bass Boost: The ZX700.5's subwoofer section has a bass boost circuit that provides up to 18dB boost at 40Hz; the boost is continuously variable from 0 to 18dB.

Fader: You can connect one, two, or three pair of input cables to the amplifier. If only one pair of inputs is available, the amp's Fader button allows you to feed signals to all six channels from the single input pair. In this case, the fader of the source unit will not affect the output of the amplifier. If two or three pair of inputs are available, the amp's Fader button should be turned off, allowing you to use the fader of the source unit to control the front to rear volume of the amplifier. If front and rear preamp inputs are available, but no sub, the Sub Input button allows you to feed the subwoofer amp from the Amp1 inputs.


Left Side of Amplifier:

  • +12V (power): gold-plated set screw terminal (accepts up to 2 gauge wire)
  • REM (remote turn-on): gold-plated set screw terminal (accepts up to 12 gauge wire)
  • GND (ground): gold-plated screw set terminal (accepts up to 2 gauge wire)
  • Fuse: three 30-amp ATO fuses

Right Side of Amplifier:

  • Auto Turn-on Selection: 3-way switch (+12V, DC Offset, Audio)
  • Crossover: 2 switches (Amp1 and Amp2); high-pass or Off (full range)
  • Input Level Switch: 2-way push button (Low, High)
  • Fader: 2-way push button; on/off
  • Sub Input: 2-way push button; Amp1/Sub
  • Speaker Outputs: gold-plated terminal strips for Amp1 (stereo), Amp2 (stereo) and Sub (mono); each accepts spade connectors up to 0.34" wide
  • RCA Inputs: gold-plated RCA input jacks for Amp1, Amp2, and Sub Amp
  • Remote Bass: RJ-14 jack for use with optional ZXRC remote bass level control (ZXRC will only work with the subwoofer output)

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


Warranty Note: The warranty on this amplifier is 2 years parts and labor. If the amp is installed using a qualifying Kicker amplifier wiring kit, in this case item number 20609PK4, the warranty is extended to 3 years parts and labor. The amp and wiring kit must be purchased on the same invoice from an authorized Kicker dealer (Crutchfield for example) and the warranty extension is only valid in the USA.

Great sound!

Written By J-Mac, Alpharetta, GA on Tuesday, March 08, 2011
I replaced a Memphis amp in my 26' boat with this killer amp. I have it
running 4 JBL M650's 6.5's and a 10" sub (about to upgrade to a 10" JBL
HO110RG-W3v3 ). Sound is loud and clear. it's nice to have the adjustments on
the top of the amp rather than the side so tuning was a breeze. Sound is so
much better than the memphis it replaced. very happy, I am considering buying a
second to replace the other amp I have running the other 4 6.5's on the boat.

Awesome Amp

Written By jc, SoCal on Monday, March 07, 2011
Crutchfield Customer Review (What's this?)
This is a great amp. It was recommended by a Cruthfield advisor, and I think it was a great
call. I am running a set of Alpine 6.5 type R components and a set of 6x9 type R coaxials
along with Rockford 12 P31412 Sub. I have this system in a new Camaro running of a
Pioneer P4300DVD head unit. The amp powers everything with ease, its rated at 700 watts
but the birth sheet said 987 watts. The system sounds great . If your looking for a single amp
solution this here is it. I picked up the kicker amp wiring kit which bumped up the warranty to
three years. The best thing too is that it was on sale when I bought it.

Good for standalone installtion

Written By DavidR, Seattle, WA on Monday, January 24, 2011
Crutchfield Customer Review (What's this?)
Install was quick & easy. No major issues with what is a fairly standard amp unit
installation. I bought it to connect directly to my DroidX phone without going through any
head unit. The dual inputs allow a secondary 3.5mm input from another device (iPod
Touch) - while the primary device supplies navigation instruction, music and handsfree
phone operation. Set up and dialing in the levels was easy and fast. The only issue I
had was with the audio signal detection on switch. I was unable to get the system to
power on with the signal from my phone. I wired in a +12V switch - which is probably
better choice in the end. Overall, nice unit. Can't wait to get the sub wired in too.

With power to KICK!!!

Written By SteveL, Mpls, MN on Friday, November 19, 2010
Crutchfield Customer Review (What's this?)
After much reading and still having trouble deciding what to buy to go along
with the JVC Arsenal KD-AHD69 head unit and two pair of Infinity Kappa 682.9cf
100W RMS speakers, I called Crutchfield. I told him I wanted to buy a sub and 5
channel amp to drive my speakers along with the sub. Well he did a great job with
recommending this Kicker amp! This amp pushes 70W RMS to my
four 4 ohm speakers and 420W RMS to my 450W RMS 2 ohm Kicker enclosed sub. Just
how you want it and the system is loud and very clean. Thanks Crutchfield. Oh
yeah, I picked up the Kicker 09PK4 4 gauge wiring kit too. Very nice stuff.
