Certified Output and Reliable Efficiency

High powered subwoofer applications tend to generate plenty of heat to the amplifier powering them. Music can only be enjoyed when an amplifier is on, and when an amplifier reaches high temperatures it will usually shut off to protect from it damage. The Kenwood KAC-8105D has a built-in heatsink to protect from high temperatures so your system can play longer without having forced intermissions.

With an impressive output rating of 300 watts RMS x 1 Channel at 4 Ohms, and 500 watts RMS x 1 Channel at 2 Ohms, this amplifier is CEA-2006 compliant so all wattage specifications are true to industry standard. Combined with their total efficiency and high power output, the Kenwood KAC-8105D is the perfect option for any compatible subwoofer application!

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.
300 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.
500 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 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
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.
0.8%
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
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 25 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.
80 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
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
30A x 2 
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.

Bang for your Buck

November 25, 2010

Amp pushes 500w RMS at 2 ohms which is perfect for my two MTX Terminator twelves that are rated 300w each so its giving them both a solid 250w. I've taken it on multiple 3 hour trips and has never overheated. For those of you bridging your amp and complaining about them overheating, you need to buy a monoblock. Bridging puts much more stress on the amp and you can get the same power output from a monoblock without putting additional streets on the unit. Sounds great for a low wattage system.

April 14, 2013

I' am running this amp to the Jackhammer dual 12" ported enclosure. I have had this setup for a couple of years now and I' am very impressed. I run it in a 2001 Oldsmobile Alero Sedan with two Bi-Amplified SoundStream 6X9s run by another amp in the rear deck. I listen to rock only no rap. This set up is pretty loud I must say and very reliable I have had 0 issues. the amp is screwed to the back of my enclosure and sits between the enclosure and the rear of the rear seats. I never have any issues with clipping or overheating. I would recommend this amp.

I bought this as my first amp when getting started into the car audio game. This amp has held perfect for what i've put in my car which was a 10" and 2 12" Dual subs. I was pleased with it. If your looking for something cheap but good, buy this. I myself am stepping up my game and going from this kenwood to a Rockford 1000.1bd. and hopefully new subs once i get the cashflow

Great amp. Sylish, too!

March 14, 2013

I used this amp to power 1 alpine sws-10d2 sub. I have the sub wired to 4 ohms, which gives it 300w rms. Even though I don't have it running the whole 500w rms, there is still plenty of power to rock you car and shake the mirrors. As for the design of the amp, it looks very cool with the blue and red lights on the top. My only prblem with the amp is that the wires and control knobs are on the same side of the amp. The way my amp is mounted, it makes it difficult to adjust the bass when I first set it up. After it is tuned though, its not as much of a problem. Overall, this amp is a great investment, and it still has plenty of power left for adding another sub in the future!

It's a powerful amp with a compact size. Fitted perfectly behind the passenger seat in my Ford F-150 (standard cab). In fact, the audio shop that did the install just bolted the amp on my Sony boxed subwoofer. Never had any problems with it. The sound quality was excellent. Very satisfied with the product.

Definitely an instant classic in modern car audio

November 12, 2012

Bought this Kenwood amp not knowing what to expect, as I had never owned anything from Kenwood's "Performance Series" line of car audio products. Let me tell you. . It's definitely an instant classic. Not many other amps out there can promise the same wattage for the same dollar (except maybe HiFonics, and even then you know it's not true). Being CEA compliant, I have full faith that this amp does what it says it does. It seems a bit power hungry for just 500 watts RMS though, as it makes my lights dim depending on the gain setting. I use it for occasional musical enjoyment, not really everyday use. I don't have a capacitor, nor have I done the "Big 3" upgrade. Having said that, a true enthusiast should probably do these before purchasing this. The sound is amazing. Clean bass no matter what you're playing. The settings are simple to use, yet functional. The overall design of the amp is classy, in my opinion. Overall a solid, great value for plenty of good sound. Would recommend in a heartbeat.

I purchased this amp for the class D series and match up to my excellon reciever. To fire my 12" CVR dual 4 ohm. A perfect match it was. No need for a remote boost control. Take advantage of the KW reciever controls. This 8105D is running at 2 ohms. With a little adust its totally pounds. True watts. Looks so killer in design. Never even gets hot. Just wire it up correctly give it perfect ground the proper volts. I gave it shurken from Sonic. I highly recommend. You wont be disappointed. It pushes my 12 so hard my door seals will leak water in on a heavy rain day. Thanks Sonic.
