Class D KICKER Power

Introducing the newest line of Kicker amplifiers, the IX Series. For the first time ever in Kicker history, they have entered the world of full range Class D technology. The amplifiers have been carefully designed and engineered with the incredible attention to detail, intense research and development, as well as proprietary Kicker components that only Kicker amplifiers are made with. The result is a dependable and highly efficient Class D amplifier that can produce an enormous amount of power. The Kicker IX amplifiers also feature the smallest amp chassis that Kicker has ever manufactured. The compact size enables the amplifier to fit in the smallest compartments of the vehicle. These amps are so small that some installers have been able to put these amplifiers inside of a glove compartment! The amps are so efficient that they are able to run all day long with little current draw and very little heat generated. Even though the heat sink is less then 10" in length, the amps still are barely warm to the touch after hours of intense use. Kicker makes the choice easy. For a high-powered, highly efficient, and compact amplifier, choose the Kicker IX amplifiers.

Full Range Class D mean High Output

The four-channel IX amplifier is a one of a kind. Offering a full range of amplified frequencies across four audio channels. With the installation of this single amplifier, a vehicle can have all four speakers powered with Kicker power. For the Kicker IX500.4 amplifier that means 75 Watts x 4 Channels at 4 ohms, and an impressive 125 Watts x 4 Channels at 2 ohms! No matter what type of after market speakers are installed, the IX amp will provide plenty of clean power. Since the amplifier is bridgeable, it can be configured in 4 channels, 3 channels, or 2 channels. It also features an advanced 12 dB/octave electronic crossover for the finer acoustic tuning. Following Kicker's tradition of high output, each amp exceeds the rated power. That means the 500 Watts RMS is actually more than that. Each amplifier is tested, rated, and given a "birth sheet" in the Kicker factory that listed the tested power. Every amp exceeds the rated power. That just one more reason to choose Kicker!

Power Specifications - Full Range Channels

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 speakers or subwoofers 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.

75 watts x 4 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 speakers or subwoofers 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.

125 watts x 4 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

250 watts x 2 channels
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 occurring. 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.

250 watts x 4 channels

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.
4
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

1000 watts
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.

500 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.
4 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.
4 ohms
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.
No
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)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below 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
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.
98 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.
No
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
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 Amp!!

June 17, 2011

I am over 40 and have owned several amps over the years. This class D four channel amp is one of the best I have ever owned and is without a doubt the most efficient! Bridgeable down to 2 ch. The heat sink is only 10 inches. You could mount this amp almost anywhere. It is crystal clear and extremely loud! I will be buying another for my boat very soon.

Clean sound

March 1, 2012

I chose this amp for the limited amount of available space and low current draw I was looking for. I like the ability to stack multiple amps and have them still run cool. I have played it loud for extended periods of time and have never had any hiccups.

Kicker class D

January 23, 2012

This amp is bangin!!! You don't need anything bigger for your high and midrange speakers. I have focal polyglass mids and high range speakers and this amp pushes them to their max. I can't turn my music up all the way with out irritating myself. This amp was definitely a good investment for the discounted price I paid for it. I will be back to order more equipment when bring my caprice out of storage this summer.

First digital amp

January 19, 2012

I had an oldschool MTX 40x4 running 4 MB Quart 6.5 on 2 channels at 2 ohm stereo and the other 2 channels 4 ohm mono on 2 8 ohm MTX blue thunder 12s in parallel. System sounded great but I wanted more power and headroom in a small amp that would fit in the cubby hole under the floor in the back of my 98 pathfinder. After some research I purchased the Kicker IX500.4. 75x4 It is a nice strong amp. It did what I wanted for the bass but the mids and highs sound a bit harsh compared to the MTX. I would recomend these class d amps for bass amps but like the more natural sound of a class a/b amp for the mids and highs. Amp runs cool but I do have a fan on it. Over all I think the IX Amps are solid for a bass amp.

Great Amp.

November 19, 2011

I just put this in my car with 4 Kicker 6x8's. It sounds great and looks very nice. I was pretty impressed by how small and heavy it is (which is always a good sign). Also, I like the simple look of it and the blue LED that comes on when it powers up. It was also small enough to mount on the back of my fold down back seat. So far, this seems like powerful yet inexpensive amp.
