Versatile adjustments and setup

A built-in low-pass filter lets you adjust the output 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 fatten up the sound. An aluminum cover plate protects the amp's controls and connections, giving your installation a professional look.

Package deal: Save money when you buy this amp as part of these Kenwood dual 10" or dual 12" bass packages.

Bought this refurbished and you would never know. Works great. Inexpensive for a name brand product. I have two Alpine SWA-10S4 speakers hooked up to this and has plenty of punch.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining 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 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and over a frequency range of 20 Hz to 20 kHz, when applicable (20-200 Hz for this subwoofer amp). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Kenwood KAC-5001PS is rated at 300 Watts RMS x 1 channel with an 83 dBA signal to noise ratio.

Specifications: The manual also lists these non CEA-2006 compliant specifications:

  • Power: 500 watts x 1-channel (into 2Ω, at 100 Hz, no more than 1.0% THD, 14.4 volts)
  • Signal to Noise Ratio: 100 dB (at rated power)

Mono-Power Amp Design: The KAC-5001PS is designed with specific features to power your subwoofer(s) with a frequency range between 20 and 200 Hz. This amplifier is not designed to power a full-range speaker.

Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is much higher efficiency (less heat generated) than Class AB.

Low-Pass Filter: The built-in 24 dB/octave low-pass filter is continuously variable from 50 to 200 Hz. The crossover is always engaged (it cannot be bypassed).

Bass Boost: The bass boost circuit is centered at 40 Hz; boost is variable from 0 to +18 dB.

Controls:

  • Input Sensitivity: 200mV-5V; continuously variable
  • Low-Pass Frequency: 50-200 Hz; continuously variable
  • Bass Boost: 0-18 dB; continuously variable

Inputs and Outputs:

  • Signal Input: one pair of RCA inputs
  • Power: screw terminal; accommodates spade connector up to 0.55" wide
  • Ground: screw terminal; accommodates spade connector up to 0.55" wide
  • Remote Turn-on: screw terminal; accommodates spade connector up to 0.335" wide
  • Speaker Output: one pair of screw terminals; accommodates spade connector up to 0.335" wide
  • Fuses: two 30 amp ATO fuses

Crutchfield asked  
Why did you buy this?

Lotsa power [ JEFF  Mar 15, 2016 ]
To power my 10 inch Jensons [ David  Jul 18, 2016 ]
This amplifier may be refurbished, but it puts out 300 watts at 4 ohms. The subwoofer I just purchased has an RMS of 350 watts at 4 ohms. It's a powerful mono amplifer (powers only one speaker) that won't put out too much power for my subwoofer. [ Hunter  Jul 09, 2016 ]

Thanks for your question. For information on selecting the best amp for your sub I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Kenny  Mar 27, 2017 ]  Staff
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Kenny  Dec 24, 2015 ]  Staff
Its not melting anything but you don't want to touch it very long and the fan is running [ steve  Jul 20, 2014 ]
You have power to your amp,does it run really hot? [ steve  Jul 19, 2014 ]
Hello, that means it is turned on, has an active power supply, and the remote wire is hooked up correctly. Thanks, Clint MVP Motorsports [ CLINT M  Jul 14, 2014 ]
Thanks for the answer and incredible info to match. It also means I need a new amp to power the kicker or a new sub to match the Pioneer. But maximizing potential seems safer then under powering according to those links. I figured if I bought a sub that the amp couldn't blow I would be on the safer side, but apparently I figured wrong lol. Thanks again Krissy, forever in debt to your priceless advice ;-) [ John  Jun 27, 2014 ]
I forwarded your question to an Advisor and they responded with the following: The amplifier will automatically recognized the impedance that the subwoofer is showing to the amp and it will output the amount of power according to the impedance of the sub. Here is something that may help you understand a bit more: http://www.crutchfield.com/learn/wiring-subwoofers-ohms.html?showAll=N http://www.crutchfield.com/learn/how-to-match-subwoofers-and-amplifiers.html?showAll=N If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

Unless there is a third party controller you can find, there is no way to plug anything into the amp to control the bass output. Hope this helps. [ TYLER  Feb 15, 2014 ]
The Scion XB I installed this amp in powers a pair of 12" Kenwoods subs. I believe the sub is under powered for the application. The factory head unit in the XB has a sub output level control which is ideal and can't imagine why you couldn't install an inline contoller. [ DONALD G  Feb 14, 2014 ]

Right now I have a kicker 300.1 pushing all three and it is a mono so than it might work right? [ Benoit  Jul 13, 2016 ]
Have one pushing 2 rockford 10's, it works great, but I doubt it'll push all 3 of those together, all the subs need the same rms rating to use the same amp, and it depends on the total rms of all 3 subs together. So I'm sorry I can't truly help without knowing what subs they are. [ Andrew  Jul 13, 2016 ]
Its a mono amp which means it only has one set of outputs on it, so you can get two subs going with it but not the third set. [ NATHAN  Jul 13, 2016 ]
