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 08ZX750.1 mono subwoofer amp will drive your subs with up to 750 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 the bass notes to your subwoofer, and use the subsonic filter to remove 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.

Product Highlights:

  • mono subwoofer amplifier
  • 375 watts RMS x 1 at 4 ohms (750 watts x 1 at 2 ohms)
  • variable low-pass filter (50-200 Hz at 24 dB per octave)
  • variable bass boost (0-18 dB at 40 Hz)
  • subsonic filter (24 dB at 25 Hz)
  • wired remote bass level control
  • Class D design
  • CEA-2006 compliant
  • speaker-level inputs (requires an optional adapter)
  • preamp outputs
  • fuse rating: 40A x 2
  • 4-gauge power and ground leads with 80-amp fuse recommended — wiring and hardware not included with amplifier
  • 14-11/16"W x 2-3/16"H x 9-5/8"D
  • warranty: 2 years
  • Our 60-day money-back guarantee

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.

A strong amplifier...and a good deal

Written By Beau, Nashville, TN on Wednesday, October 14, 2009

I have this Kicker amp. I must say, I was doubting how much wattage this amp could dish out at first, judging from the looks of the amp's terminals, etc...Now it doesn't exactly have JL Audio's quality, but for the money you are getting some clean power and a lot of it....it produces maybe a tad over 750 watts which is Plenty for the dual 10" or 12" Kicker CVR 2 ohm ported enclosure... pretty much a perfect match there...This amp is a solid contender for its price, and also having the remote bass level knob included is great... however in my opinion, an amp that is a little more powerful and cleaner is the JL Audio HD750/1... although it lacks a bass frequency "boost" control, it can dump 750 super-clean watts into a 1.5- 4 ohm load, and fit places the Kicker amp can't without overheating... But friends, if you are looking for a serious amp with extremely clean, HUGE power that's versatile, wait & save up, or put the JL Audio 1000/1v2 on a credit card plan with Crutchfield.

Crutchfield Customer Review (What's this?)

I bought it at Crutchfield since I was getting a HU from here as well. Well after less than a week the amp went out. I tried to call customer support and they did not know what to do with me. After talking to 3 different people I told them I was going to return the product. This is a good amp, I think Crutchfield just got some bunk stock.

Under Rated..... Just A Little Bit

Written By Fraws, Waterbury, CT on Saturday, August 29, 2009

I have this amp installed into my 2009 Mustang GT and it truely holds its
own. This amp works extremely well and is such great quality it produces
excellent power. Setup: Kenwood DPX503, Kicker KS680, KS6502, DCVR10,
ZX7501. The amp is powering the DCVR10 without any problems. Just a bit
loud, maybe louder then I expected.

Won't get again, sorry kicker

Written By christian, Los Angeles, CA on Thursday, July 30, 2009

Well I bought this bad boy because of all the hype that I heard about it. Hooked up to 2 10" w3 with a cap. Loved the power that it had, great sound and got lots of compliments on it. Then after about 3 weeks of usage my silverado started smoking from the back seat, and not just a couple of puffs but the chimney type of smoke. Thankfully it was still under warranty so we'll see how the new one holds up. Honestly it was probably my fault for having the base knob maxed out for two days straight.

Sick Amp!

Written By Kristine, Townsend, MA on Friday, July 24, 2009

I just bought this and installed it in my 02 Protege5, along with the cvr 12
2ohms, and I have to say by far the best ive had yet!


Written By William, Charlotte on Monday, July 20, 2009

This is an excellent amp. Underrated, comes certified at over 900 watts
rms. Mine is 963 rms.

I have it hooked up to two 12" Kicker Comp CVR's in a Jaguar X-Type and it
hits hard.

You WON'T find a more powerful amp out there for the price of this thing.
Highly recommended!

I just ordered another one to put in my RX-8.

Buy this amp.

Nice Amp

Crutchfield Customer Review (What's this?)

This amp is definitely worth the money. Its pushing two Sony 12s and it sounds awesome.Probably the main reason why I bought this amp was the signal sense auto turn on. I wanted to keep everything factory on my 09 Dodge Charger and this amp made it possible without buying any extra sound processors. It made everything much more convenient since all I had to do is tap into the rear speakers. Plus it comes with the remote while with other amps, you will purchase the remote separately. Now all I need is Dynamat because this baby rattles the heck out of my trunk.

always wanted a kicker amp.

Written By j.o, Ill. State on Monday, April 20, 2009

i bought this amp to push 2-12" alpine type-R 2ohm dvc in a ported box,
my subs are 500w rms a piece so i thought i needed more power for the subs. man i was i wrong. i bought a zx1000.1 at a different web site. so when i got the zx1000 it sounded like the zx750 i should have stuck with the zx750 it has power, shakes the heck out my SUV. so the only reason way i didn't give this amp 5-stars is you have to take time to adjust the gain, bass boost, and crossover to get the right bass thump (depending on the listeners preference) which was the problem all along.

This is it

Written By james, Mount Vernon,WA on Tuesday, April 07, 2009

I don't know how many people I've had walk up to me at the gas station or grocery store and been like" We hear you like 2 or 3 minutes before we see you, what do you have in that blazer?" and when i show em its two kicker cvr 12"s and this amp they are amazed. Livin loud is not just they're motto, its what they do for real! I've had the 06 model in my previous car and this one in my current vehicle and never had anything but great performance out of either. Def recommend to any bass head out there who don't want to spend all their hard earned money, but still want to rattle their neighbors windows.

Best Boom for the $$

Crutchfield Customer Review (What's this?)

This Amp has the serious Power your looking for, and for the best price. I
use it to push 2 Kicker 07DCVR122 in my Rav4 and i was not let down by
any means.
I would however recomend getting a Farad cap of some sort to combat the
dimming of the lights when that bass hits hard, you know how we do ~

Great product & great service - just like we expect

love it

Kicker 08ZX750.1

Written By vjo90rs8, San Jose, CA on Thursday, October 23, 2008

1. You should never use the bass boost knob unless you want boomy, terrible sounding bass (although small adjustments are usually okay depending on the listeners preference, but only 40Hz is boosted)
2. You probably didn't set your gain correctly because you have 3 things to adjust, bass boost, gain, and crossover. You want to match your gain to the amps output and/or subwoofers RMS ratings.
3. The low pass filter crossover is adjustable from 50Hz to 200Hz, so if you set it to 50Hz then all frequencies below 50Hz are played by the subwoofer. You are not missing the low frequencies, it is a lower pass filter, not a high pass (which would not make sense with a sub.)

I do not have a 750.1 but a 400.1 which is rated at 480W and it is a perfect match for my Alpine Type R 10' and sounds great. I just didn't want people to be turned off by a negative review.

Nice Amp

I have the Kicker 08ZX750.1 and its a great product to buy. I have it installed in a small one cab pickup with two Kicker CVT's and its of great quality. The bass is lound like I like it but it also has great responce in all kinds of music.

this amp says 750 but mine is rated at 936 rms. i have this paired with an L7 12in and its extremely loud and has low end bass.

no low end bass

Written By james big, california on Monday, June 30, 2008

I bought this amp with great hopes and spent alot of money thinken I was geting the best!!!!! boy was I wrong...........There really is no low end bass!!!The only way to make this amp sound almost decent is too turn the bass bost all the way down......So you can only adjust the low pass and thats it!!!Plus the low pass is 50hz so your missing part of the bass.The low rumbling bass that I love.....................On the plus side this amp has alot of power.and will make your car shake.Also I think it whould last along time.But If you really want your music to sound good.Don't buy this amp,buy a mtx,eclipse,Jl slash or a fosgate.

Product Research



CEA 2006 Compliant: The ZX750.1'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 if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The manual lists two signal to noise ratios:

  • CEA 2006 compliant: 68 dB
  • At rated Power: 95 dB

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 ZX750.1 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 attaching RCA plugs onto the speaker wire, and set 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 ZX750.1'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.


Low-pass Filter: The internal low-pass filter can be adjusted from 50 to 200 Hz, and 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 ZX750.1's KICKEQ bass boost circuit provides up to 18dB signal boost at 40Hz. The bass boost circuit is continually adjustable from 0 to 18dB.

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.


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 8 gauge wire)
  • GND (ground): gold-plated screw set terminal (accepts up to 2 gauge wire)
  • Fuse: two 40-amp fuses

Right Side of Amplifier:

  • Auto Turn-on Selection: 3-way switch (+12V, DC Offset, Audio)
  • Input Level Switch: 2-way push button (out=Low, in=High)
  • Speaker Outputs: gold-plated set screw terminals (accepts up to 8 gauge wire)
  • RCA Input: gold-plated RCA input jacks
  • RCA Output: gold-plated RCA line output jacks
  • Remote Bass: RJ14 jack for use with supplied Remote Bass Level Control

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