Power and performance for your entire system
Kenwood's Performance Series KAC-7005PS 5-channel amplifier can take care of your entire car audio system's power requirements, and then some. Start with 40 watts RMS of musical clarity to every one of your front and rear speakers, then factor in up to 500 watts RMS for your subs — it all adds up to clear, loud, and rockin' sound in your car. Got a really nice set of speakers you want to drive? You can also bridge the amp into 3-channel mode and send 100 watts RMS to each of your front speakers, along with that 500 watts of bass power.

Reliability is key
This Performance Series car amp offers long-term reliability and superior sound quality in a compact, no-nonsense package. A rugged cast-aluminum heatsink and a cooling fan keep this amp running at optimal temperatures, even when you're pushing your system hard. This versatile amp features separate adjustable crossover filters for the front, rear, and subwoofer channels, as well as a bass boost, so you can dial in exactly the tone you want.

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.

Kenwood quality

Written by: R. L. Sr. from Courtland, VA on February 16, 2015

I used the amp to power door speakers, back speakers under the window, and the subwoofers in a box. I did good! The sound is like a being at a concert! I listen to jazz, raggae, R&B, pop, and old hip hop and ALL of it is superb! I have always been a Kenwood fan since I was 19 years old. I have a Kenwood stereo in the house that still sounds good! This amp is great! I am proud and thankful for the choice I made.

Pros: Great sound and does not take up a lot of space.

Cons: none

Good Amp. Difficult controls.

Written by: Jeff from Dallas, TX on January 13, 2015

Crutchfield Customer Review (What's this?)

Nice 5 channel amp with plenty of power and good sound to power 4 speakers and a subwoofer. You don't have to worry about two amps and two power cables. The controls for the gain and pass through and bass boost were tiny and hard to see even with a magnifying glass. I wanted to make sure the frequency filter was off because I was filtering it through the head unit, but I could not see how to make the switch and could not tell if it was on or off. The gain adjustment had poor markings and tiny tiny little slots to turn it with a tiny little screwdriver and an itsy bitsy marker that I could only see with a magnifying glass.

Pros: Good sound. Pletny of power.

Cons: Poor manual, and extremely difficult controls for tuning.

Amp provides good clean power for quality sound. I have not hooked up the sub yet, but am very happy with the power to my Polk 6" speakers. They sound clean and get loud with no distortion on this amp.

Pros: Quality sound, good price

Cons: none yet

Product Research



Multi-Channel Design: The KAC-7005PS is basically three amps built into one chassis, two full-range 2-channel amps (A and B), typically powering the front and rear speakers, and one mono amp to power a subwoofer. Either of the full-range amps can also be bridged to one channel.

CEA 2006 Compliant: The amplifier's power and signal to noise ratio specifications are measured according to CEA-2006 standards, developed by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The CEA-2006 compliant power output is 40 watts RMS x 4 (into 4Ω, 20-20,000 Hz, no more than 1.0% THD+N, 14.4 volt power supply) plus 300 watts RMS x 1 (into 4Ω, 20-200 Hz, no more than 1.0% THD+N, 14.4 volt power supply). The CEA-2006 compliant signal to noise ratio is 80 dBA (at 1 watt into 4Ω).

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

  • Full-Range Channels:
    • 2Ω: 50 watts x 4 (at 1 kHz, no more than 0.5% THD)
    • Bridged: 100 watts x 2 (at 100 Hz, no more than 0.5% THD)
  • Subwoofer Channel: 500 watts x 1-channel (into 2Ω, at 100 Hz, no more than 0.5% THD)
  • Signal to Noise Ratio: 100 dB (at rated power)

Cooling Fan: There is a cooling fan to help dissipate heat and ensure cool, reliable operation. Make sure not to block the vents or the fan when installing the amplifier.


Input Sensitivity: The KAC-7005PS features independent gain controls for the front, rear, and subwoofer channels. The input sensitivity of each is adjustable from 200 mV to 5.0 volts.

High-Pass Filter: The front and rear amps have individual switches to set the built-in crossovers to high-pass or off (full-range). The crossover points are independently adjustable from 50-200 Hz. The high-pass crossover slope is 12 dB/octave.

Low-Pass Filter: The subwoofer channel's low-pass crossover is always engaged (it cannot be bypassed). The crossover point is adjustable from 50-200 Hz and the slope is 24 dB/octave.

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


Power And Ground Terminals: The amplifier features screw terminal power and ground terminals. They will accommodate spade connectors up to 0.55" wide.

Remote Turn-On Terminal: The remote turn-on is a screw terminal that will accommodate spade connectors up to 0.35" wide.

Speaker Terminals: The five pair of speaker terminals are screw terminals and will accommodate spade connectors up to 0.35" wide.

Signal Inputs: The amplifier features three pair of RCA input connections, A, B, and Sub.

Fuses: Two 40-amp ATO fuses are installed in the amplifier chassis.

Customer Q&A

4 questions already asked

The sub channel is a separate entity, I would recommend replacing the head unit altogether if you're going to run this. That way you won't have to split one, you degrade the sound quality doing that. [ WILLIAM  Oct 20, 2015 ]
The sub can use the rear outputs. It will still only send lower freq to the sub. [ David  Oct 16, 2015 ]
You should use a radio with RCA jacks for the sub(s) as well if your going to use a 5 channel amp for your system Just makes it an easier set up [ Joseph  Oct 16, 2015 ]

I do not see an option to make the sub full range. [ David  May 29, 2015 ]
I forwarded your question to an Advisor and they responded with the following: There is no way to remove the low pass filter on the subwoofer channel on any 5 channel amps. They are going to only produce the lower bass frequencies. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  May 27, 2015 ]  Staff
That is what I believe to be the case, but I'm not seeing the information to confirm this for sure. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help confirm. [ Jeff  Apr 21, 2014 ]  Staff
