Reliable performer

Kenwood makes tough, rugged amplifiers that bring you superior sound quality along with reliable performance. When you power your subwoofer with Kenwood's Performance Series KAC-9106D amplifier, you'll hear all the great tonal color, impact, and detail in your music's bass, from the hard punch of the rhythm section to the soft thump of a quiet kick drum.

The KAC-9106D mono amp puts out up to 1,000 watts RMS to your subwoofer. Onboard low-pass and subsonic filters let you adjust the signal so you'll get the best sound possible from your subwoofer/box combo. You can dial in up to 18 dB of bass boost if you want to really fatten up the sound.

This versatile amp features speaker-level inputs and signal sensing turn-on, so you can put this amp to work in just about any kind of system. Aluminum cover plates cover and protect the amp's connections and controls, giving your installation a neat, professional look.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples). Using CEA-2006 criteria, the Kenwood KAC-9106D is rated at 500 watts RMS x 1 channel with a 76 dBA signal to noise ratio. The signal to noise ratio at the rated power output (not CEA-2006 conditions) is 100 dB.

2-Ohm Stable: The amplifier can also support a 2-ohm load; the 2-ohm power output is 1,000 watts RMS x 1 channel.

Cast Aluminum Heat Sink: The KAC-9106D utilizes a cast aluminum heat sink design to ensure the amplifier stays cool.

Protection circuitry: The amplifier features protection circuits that will turn the amp off in case of the following events:

  • speaker wire short-circuits
  • speaker output contacts ground
  • unit malfunctions and DC is sent to speaker output
  • the amp overheats

Power Indicator: When the amplifier is turned on the Power indicator (on top of the amp) lights up. This indicator turns off with the amplifier, and will turn off if the amplifier goes into protect mode.

Auto Turn-on: When using a speaker level input, the amp will turn on automatically when it senses the input signal.

Controls

Gain: To accommodate the varying range of signal levels from today's factory and aftermarket radios, the KAC-9106D features an adjustable gain control; 0.2-5.0 volts line level (RCA) and 4.0-12.0 volts speaker level.

Crossover: The built-in 24 dB/octave low-pass filter has a continuously variable crossover point; 50Hz to 200Hz. Because this is a subwoofer amp, the crossover is always engaged.

Infrasonic Filter: The 24 dB/octave Infrasonic Filter removes ultra-low frequencies that cannot be reproduced by most subwoofers. These frequencies do not become sound, but unnecessary oscillations which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to speakers. The filter's crossover point is continuously variable from 20 Hz to 50 Hz.

Bass Boost: The bass boost is adjustable from 0-18dB at 40Hz.

Connections

Power Connections: The power and ground connections are 0.55" wide screw terminals. The remote turn-on screw terminal is 0.335" wide. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are recommended. The manual lists a minimum of 10 gauge wire for power and ground, but given the 120 amp fuse value and the current consumption specification of 65 amps, we recommend a 4 gauge wiring kit.

Speaker Outputs: There are two pair of 0.335" wide screw terminal speaker outputs; they are internally wired in parallel, making it easy to connect two subwoofers. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are also recommended for the speaker wires.

Line Level Input: The line input is a pair of stereo RCA jacks.

Line Level Output: The amplifier has a pair of RCA line level outputs for feeding another amplifier; it is the same signal that is input through the RCA line inputs. The amplifier's crossovers have no effect on the line level output signal.

Speaker Level Input: A wiring harness is included for the speaker level input.

Fuses: The amplifier uses three 40-amp ATO blade-type fuses.

Simply AMAZING

Written By Certified, Knoxville, Tennessee on Thursday, October 16, 2014

Crutchfield Customer Review (What's this?)

I believe this amplifier is the most amazing amp ever made. The tuning capabilities are infinite. I am able to push my 12" subs to their limits. Others can NOT believe that it is only 1000W and two 12" subs destroying their thousand dollar systems.

Pros: The capability to fine tune the sound and being able to subtract the unnecessary oscillation of the speakers when there is no sound coming from them.

Cons: I have yet to find one.

5 Stars!!!

Crutchfield Customer Review (What's this?)

Best amp for your money! I'm very impressed. For many years I've only had jl audio slash series amps and this amp does the same and puts out almost the same quality for power and sound! I'm running a jl audio w6 v2 on a 2 ohm load and this thing feeds it more than enough power =)

Pros: Price, quality

Cons: None

Tons of power

Written By Ben, Silvis, IL on Thursday, August 07, 2014

Crutchfield Customer Review (What's this?)

Tons of Power output, doesn't kill your battery.

Pros: Stays cool with high output use.

Cons: My face plate was for a different model.

Overall a great amp that is easy to inatall

Well worth the money

Written By Degs, Regina Saskatchewan on Wednesday, June 25, 2014

These amps can,t be beat for the price of them, I had a Audison mono bloc amp that was suppose to be 1200 watts (RMS) end 3 times the price of the Kenwood -9106 D. I still kicking my butt for buying that Audison, It was the worse sounding amp I ever had in my life. The kenwood blows the Audison away, I only got the gian turn up not evan a quarter ways, End it shakes the whole car, Wth 2- 12 Alpine R series subs in a seal box, I have the subs wired down to 2 (Ohms) End run my car stereo at 3/4 volume all the time, When I playing my stereo, End I in my car for hours driving around, End never had a problem with it. I have install car audio for over 38 years on end off, I have had lot of kenwood mono bloc amps tough out the years, Since 1987, From a KAC-9152 D. Down to the KAC -9102 D. End they all were very good amps. With no problem with them. End really thump. you can,t go wrong buy buying one of these amps.

Pros: Easy to install, Doesn,t take up much room in vehicle, Verry clear sounding if set up properly. Good bang for the buck.

Cons: getting it fine tuned properly
