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

Peak Power @ 4 ohms
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. However, some manufacture's do not provide an RMS figure and therefore one cannot be advertised.

Bridged Peak/Max 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 Peak/Max power created once an amplifier is bridged.

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.
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
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
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 
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
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.

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.

This amp is fantastic

September 5, 2012

I hooked this amp up to two 12" MTX terminator subs and turned up the input sensitivity and LPF and they hit so hard. I took that setup on a 4 hour car drive through Illinois and the amp did not overheat during the whole trip (with the car running and audio going the whole time). Class D amps are the only way to go for subs and anyone who uses A/B is doing it wrong ;D

Amp powered on, but would not produce a signal to the subwoofer. Testing with voltmeter, multiple head-units and another amp confirm diagnosis.

Installation was time-sensitive so I have purchased another unit locally, and am awaiting RMA refund - will return to report on performance of new unit.

Solid entry level amp

May 27, 2012

I bought this when they had their black friday deal. So far the amp has held up perfectly fine. Being a entry level amp, it was a solid investment for my 12" sub. I had the audio shop professionally install my system so they pre-set the amp settings. It was powering my 12" MB Quart ONX304 and ended up blowing it. I figured the extra 100wrms delivering into the sub caused the sub to fail. That should tell a bit how the amps power wattage is accurate as rated.

Ahhhh My First Amplifier

March 16, 2012

For what it is, its great if your just getting into car audio and want something to make your car beat, it serves that purpose perfectly. Its only real fault is that its ENTIRELY to power hungry to only push out 500 watts, the purpose of the 500 watt system is to be just powerful enough to shake stuff around, but not quite comp worthy. Or (if your like me) to add some extra low end to aid the musicality of your car. You really shouldnt have to do any extra to maintain a 500 watt system, good wires and stock everything else should do the trick. Still, this amp gave me some good times in my prelude, i most definitely recommend it if your looking to get into the game.

For the price, I really think you'll have a hard time finding a better sub. I know a lot of audio snobs look down on Kenwood, but this is a solid amp. It looks great, and it puts out very well.

I was slightly disappointed at the lack of a bass remote(very useful), and the adjustment knobs were difficult to access. But like I said, If you're setting your first system up, this amp will treat you well.

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.

I first got one of these amps, being an avid believer in their speakers which i still am. My kenwood 5x7s and my headunit have treated me well. But i have gone through two of these specific amplifiers in less than 6 months. And my friend burned through his excellon 1700w amp very quickly. In short do not buy kenwood for amplifiers everyone i talk to in the audio business has told me never to buy their amps because they know they'll eventually burn out.

Great beginner's amp

August 24, 2011

I've owned this amp for a few months now, my first amp. Have to say it really kicks for the price its at. Have it powering one Kicker CVR 10". Already not enough for me, so I'm saving up about $3000 to sink into a serious system now that I've learned the basics and am confident in my own abilities. For the guys that say it cuts out on them, monitor your voltage because if you are running this on stock electricals (no "big 3" upgrade etc) then you are experiencing voltage dips likely down to 11 volts. First off this means the amp is working much much harder to provide the same output, and second off it means that you arent getting as much power to your sub as you could.
Putting in a second battery or possibly just a capacitor may help a little but if you want that big of power you are going to need a more expensive amp.
I have yet to do any real upgrades to my own equipment besides a cap (which was like a bandaid on a cut artery) and even just my 10" CVR gets anemic for power at a certain level.
If you are serious about your BASS then you will want more from this amp. I would say unless you are willing to upgrade your electrical system, go with a better amp such as the KAC-9105D.

Decent Amp

July 1, 2011

This amp is a bang for the buck kind of amp. It shorts out a lot even when tuned down, all because of stupid "protection mode"... really embarrassing when you show friends and it just stops outta nowhere. Get this amp if you are powering a low wattage sub.

Good amp!

May 30, 2011

I've had this amp for about a month now,and Im completely satisfied with it. Never experienced any of the heat issues others have talked about. In fact its barely even gotten warm expect for when I had my gains set wrong and was pumping it hard for about an hour(even then, it was still barely warm). Then again, I have it matched perfectly RMS wise to a 300rms Infinity sub. I also added a PAC-LC1 remote to it, and I'm enjoying it now more than ever cuz I can dial in just right amout of bass to go with different types of music now. I recommend the PAC-LC1 to anyone whos amp doesn't have a remote or sub control on their head unit.
But back to the topic...if you're looking for a good entry level/budget amp, this ones got u covered! Look no further. This amp is solid, it puts out a clear signal, and its priced right.

This amp is a must buy if you have a sub that needs 500w rms and up to 1000w peak. Its never overheated or cut out. I have it mounted under the rear seat of a jeep cherokee ad this thing pounds!! Highly recommend this amp, you wont be sorry.

this amp is very good for the price offered here, i bought mine at b***b** for 199 plus tax and a $25 four year replacement program. This amp is sooo much better than the legacy rebel amp offered for this same price. with this amp and two 12s you can hit 138 decibels (+/- 5). Good entry level amp. It hardly draws the alternator at all.

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!

I purchased the 8105D to power a DVC 12. The amplifier performs flawlessly and remains acceptably cool while hard driving the 12 and it's overall quality is comparable to higher priced units. For someone who has a receiver without sub-woofer controls, a remote would be a plus but I would still recommended the amplifier to anyone.

Only downside is amp will overheat within 10 min. at max.gain and max. volume. I have mine mounted on top the box in my Ford Focus. Not much room to breath with only about 3" clearance of rear deck. Great overall amp for the price.

November 4, 2010

I bought this amp at a stereo shop locally, where they have given it great reviews as long as its tuned properly. I decided to go with since I just bought a Kenwood head unit. Im using it to drive a sub that handles 750 watts RMS and 1500 peak. Its a 4 ohm load, and I know this is only rated at 300 rms x1 @4 ohms, but WOW. This amp drives that sub very nicely and then some. With the cap i have NO light dimming and i am getting amazing bass. I am very happy with this the only thing i wish it had a wired remote.

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.

It's a powerful amp with a compact size. Fitted perfectly behind the passenger seat in my Ford F-150 (standard cab).

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.

Kenwood KAC-8105D

July 14, 2012

I got this amplifier second hand about a week ago. It was used gently, but still the newest model. First things first, Kenwood has always put out pretty good equipment. They're like Alpine or Pioneer, but cheaper. Right now, I'm running them to two ten inch Alpine type E's in a massive ported bandpass box which makes those little guys pound like the cops with a search warrant. (It might be because they are in the backseat of my 84 Z28 which has about as much storage space as your back pocket). The sound is still very clean you can tell its a quality amp. It stays true to its power ratings for sure, and you can crank it for days and have no trouble. In my opinion, if this amp blew on you, you wired it wrong. It's not the 5000 watt blah blah. But for a good amount of clean bass, this amp is worth it for sure. I would consider buying more Kenwood equipment because of the quality and craftsmanship of this amp.
