Kenwood KAC-9105D

KAC Car Amplifiers

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 it from damage. The Kenwood KAC-9105D has built-in self-activating fans to protect from high temperatures so your system can play longer without having forced intermissions. That means even under stressful conditions, the built in fans will aid the heatsink to effectively cool the amplifier.

With an impressive output rating of 500 watts RMS x 1 Channel at 4 Ohms, and 900 watts RMS x 1 Channel at 2 Ohms, this amplifier is CEA-2006 compliant so all wattage specifications are true to industry standard. The Kenwood KAC-9104D also has the Capability for a 1-Ohm load to achieve over 900 watts RMS! Combined with their total efficiency and high power output, the Kenwood KAC-9105D 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.
500 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.
900 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.
>900 watts x 1 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. 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 Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Performance (Kenwood)
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.

1800 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.

900 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.
1 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.
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
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.
75 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).
Yes
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.

Yes
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.
Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.

April 4, 2011

I have owned this amp for almost a year now and have had no problems with it. I have it pushing 2 Kenwood 12" KFC-3011s at 4ohms and this thing is a BEAST! I have owned a few other amps, but nothing like this one, it has the same power as any other amp in its category at a lower price. I also own a Kenwood KAC-8404 4-channel that is pushing 2 Kenwood 6x9s in the rear and 2 Kenwood 6x8s in the front doors and its pure Sound Quality all the way around. Definitely recommend this amp for anyone looking to build a beginner to intermediate system.

Sounds great running 2 Kicker CVR's, turned up it will make your head hurt, doesn't drain alot from car electrical system, just wish the control dials were under the removable plate instead of on the side with the connections

Just a note tho, running at 2ohm load this thing gets pretty warm after 45 minutes to an hour, make sure it has ventilation

Best Amp For The Money

January 18, 2014

I have this amp running 3 10 inch subs at 275 watts each rms wired to 2 ohms and it hitting very hard at only about 25% turn up on the gain. I have owned this amp since last February and it performs like its still brand new no problems at all.

This amp is a knock out!

September 18, 2013

This amp is another one of kenwoods best. I have it powering one 12' alpine type R at 950 watts RMS @ 2ohms. This amp is one of the best i have owned so far (4 years) and I can see my self using it on many more sub builds. I wasnt big into kenwood until I plugged this amp in but man I am a fan now!

i purchased this amplifier after running through 2 soundstorm ev.4000's in a month. This amp not only sounds better, it has performed without any issues for the last two months. i am only running my 15" at 4 ohms and it shakes my entire car, i am very pleased with kenwood as a brand and will continue to buy their products, sonic electronix was great about replacing the garbage that i bought by mistake from s******.

They may cost a little more than your other amps but will deliver more clean power without turning the gain all the way up like most amps to get the power you want. Best value in name brand amps

Great Bang for the Buck

September 5, 2013

I originally installed this amp in my 06 Civic with 1 Kenwood KFC-W3013PS subwoofer wired at 4 ohms for a 500 watt load. I had also bought a 1.4 cube single sealed sub box from Sonic. And of course a wiring kit – you can’t beat the prices here. This amp has a really cool feature that allows you to feed the signal straight from your other speakers with no need for a remote turn on wire. Perfect for an install like mine where I kept my factory head unit and didn’t have to figure out how to run a remote wire. It senses the signal coming from the speaker wires to turn itself on. Even though this pounded pretty loud, I soon decided to get the most out of the amp and buy another identical sub and a new double sealed box from Sonic. Now wired at a 2 ohm load for the full 900 Watts RMS. I was already running a capacitor but that wasn’t enough (Headlight dimming). Since my starting battery with that car was kind of weak (Honda seems to think a 400 CCA battery is appropriate for Minnesota winters) and I can’t find a more powerful one that fits in the engine compartment without modifying things, I bought 2 Kinetik HC1200 (1200 cranking amp each) batteries from Sonic. I replaced my starting battery with one (Just cut a board that I put on the battery tray for the battery to sit on and strapped it in) and put the other in the trunk with a fuse on both batteries. I also did the big 3. That solved the dimming headlights but if I really crank it on the right song I get some voltage drop so next step is buying a high output alternator. Meanwhile I figured out how to take my rear view mirror off because my windshield bounces with the bass and the mirror vibrates like a mofo. Normally if I listen at volume 30 (Car goes up to 40) I don’t get voltage drop, everything rattles, I can feel my hair move, it tickles my nose, It hurts my ears, and I can even feel it in my throat on some songs. I consider that pretty loud. I recently built a custom ported box for my truck that matches the specs for my sub perfectly and that sounds so much better and is louder than the sealed box I was using so my next step is going to be building a custom ported box for my 12’s in the Civic. That should add some volume. I’m writing this review (Sonic sent an email asking for such) even though I see this amp is out of stock. That’s a shame. Hopefully they will get more because this was an awesome purchase. I would recommend this amp to anyone who is looking to get a good bang for your buck.

Cheap, good amp. Not for Longevity

July 11, 2013

I have owned this amplifier for over two years and have had mostly a good experience with it. The amp itself was fairly easy to wire in, performs quite well at high power(excluding battery limitations). Living in Kansas, you basically put everything in your car through hell in terms of temperature changes - the amp kept up like a champ... for a while. After changing cars and moving the amplifier, one of the internal circuit boards on the amplifier has failed and would cost in excess of $200 dollars to repair. The amplifier will switch in and out of protection mode(powering off the amp to preserve itself from other shorts in an audio system) and will not produce a sustainable power output. While I am disappointed with the end of this amplifier coming at an internal flaw, I have been satisfied with its performance.

Im not gonna say this is a good budget amp or "good for the price" because this amp is phenomonal. I am using a 12 inch pioneer 4 ohm and not suprised by the quality. Like the built in fan and the amp looks too cool to hide by the way. Just wish it came with the little bass boost knob thing.
