Why Choose Kicker Amplifiers:

Kicker Always Exceeds Rated Power

Kicker Performance Audio has been around since 1980 and has been producing amazing products since then. Kicker’s drive to consistently produce products that not only are great but also push the standards of the car audio industry is very apparent in all series of their amplifiers. All Kicker amplifiers are CEA-2006 Compliant, assuring you are receiving a continuous certified RMS power rating. Kicker will always exceed the rated power because Kicker is notorious for under rating their amplifiers. So really you will be getting more power than you actually pay for, which is not true for other lower end performance amplifiers that generally over rate their amplifiers. Kicker amplifiers will provide a choice of three automatic turn-on modes; remote, DC offset, or signal sense, which make them compatible with any car audio system. Along with their high-density convection heat sink for extreme heat dissipation and high efficiency MOSFET power supply, Kickers amplifiers are great way to go when selecting the perfect amplifier for your car audio system.

Kicker FIT Fail Safe Integration Technology

Kicker Fail Safe Technology (FIT):

Kicker has manufactured a new Fail-Safe Integration (FIT) technology into all of their amplifiers. The FIT technology uses isolated differential inputs in order to reject noise or electrical interferences, caused by engines, alternators or any other audio or video component throughout your vehicle. The differential inputs will use a muting circuit that will block out any additional noise that may stream down the line. The FIT technology will help created the cleanest and purest sound possible for any audio system. The Kicker FIT technology is setting the standard for high quality sound.

Power Specifications - Subwoofer Channel

RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
1250 watts x 1 channels
RMS Power @ 2 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
2500 watts x 1 channels
RMS Power @ 1 ohm
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 1 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
Not Stable
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage. Often times this maximum is achieved during a brief musical burst, such as a drum accent or low bass hit. Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison. This is the peak power output for the amplifier's 5th channel.

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

2500 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
1/0 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<1%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 200 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
95 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 18 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Yes
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
300A x 1 
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Awesome Power

June 5, 2013

I currently have this amp pushing 2-10" pioneer premier pro series subwoofers and its incredible the amount of available power from this amp. Birth Sheet:( 2870RMS ) I currently have a factory sized battery and a 350A alternator, i get voltage drop big time when i crank it up. To solve that i just placed an order for 2 XS Power XP2000's which are overkill for the system but i am a firm believer in doing it right once. I have used this amp for well over a year now and have had no issues what so over. It is a very well designed piece of equipment and i would definitely buy one again. Also the price was FANTASTIC! You will need a-lot of available power to run this amp, if you plan to order one highly consider getting an Alternator and Battery.

January 7, 2013

This amp has been my favorite one i have ever bought, yes it is extremely exspensive but, you do get atleast 2800 rms continuous power. Only downfall on this amp i see is that it does require a H/O alternator and a XS Power battery. If you are wanting to get full power out of this amp. It produces power but you have to have the batteries etc... to back it up. Overall good amp if you want it stupid loud.

Incredible power!

February 3, 2012

If you are looking for a raw power amp this is for you. Rated at 2500watts is simply an understatement, my amp arrived with a birth sheet reading 2870watts. I am running two 10" pioneer priemer pro series dual 2ohm subwoofers in a custom ported box. Have a look on youtube to see this amp pounding (RobHoffmann20). Also plan on adding a high current alternator and possibly a second battery to your system. Keep the bass pounding!

Beast!

June 23, 2011

This amp is a true monster! I started with the zx1000 and then went to the zx1500. Now I'm up to the zx2500 and this is where it will end! 3 solobaric classics are pounding hard. No complaints at all. I'm currently not running at the correct ohm load which means this amp has room to grow. Word of caution: This amp is truly not got the weak. It requires zero gauge wire and an extra battery. Forget about adding a cap. That won't get it done. I love this amp and can't wait to unlock the full potential.
