Kenwood's Excelon XR400-4 4-channel amplifier adds clarity and punch to your car's audio system, as it powers each of your front and rear speakers with 75 watts RMS. As your system changes, you can also use the XR400-4 in 2-channel mode to drive a couple of subs with up to 200 watts RMS each. The XR400-4 can fit in many different places in your car because of its incredibly low profile — it's under 1-1/2" tall.
Kenwood packed this amp with space-saving features. Class D technology reduces the size of the power supply, while the internal heatsink is tilted to reduce height without compromising the amp's cooling system. Recessed power and speaker wire terminals help to further reduce the amp's footprint, protect the connections, and give your installation a neat, professional look.
You can contour the sound with high- and low-pass filters so your speakers play efficiently and sound their best. The front and rear channels have separate gain and filter controls so you can adjust for different types of speakers. The XR400-4 also gives you the ability to "biamp" your system, amplifying the tweeters and woofers separately for greater power and control over the sound.
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.
Nice amp, fits in tight spaces
Pros: Small Powerful
I have 09 Silverado don't have a lot of room. used this amp for my door speakers .amp gets a little warm but sound great.
I have been in the market for a small for factor high quality amplifier for a year. The space this thing takes up is roughly equivalent to a paperback book . the speakers used are from PhD and cdt and were originally powered from the internal amplifier of a JBL MS8. Quality was the next deciding factor the Rockford fosgate pbr amps were contenders too but after reading about heat issues I was worried about degrading sound quality . that's where the Kenwood xr400-4 fell into play. It gets warm but never hot to the touch its tucked away in a tight spot but is a sleek looking amp to boot. The quality of sound and power driven to the speakers now is fantastic, it was like falling in love with the stereo all over.
Pros: Form factor and quality
Cons: Wish the xovers and gain knobs were on the top of the chassis
Amp came with stripped Allen head screws for speaker wire terminations. They are completely round.
Pros: Unknown. Couldn't even install.
Cons: Poor craftsmanshipCrutchfield response on July 13, 2015 Our customer support team set up a return for this customer. Refurbished products we sell come with the same 60-day return policy that new items do, so you can make sure you're satisfied with your purchase from Crutchfield.
For the price this amp is amazing .. I usually go with a jl audio for my 4 channel but this one had decent reviews so I gave it a shot, that and my deck is an excelon .. I have this amp pushing a type r 6.5 component set in front and a alpine type r 5.25 set in rear .. More than enough power for all and the design profile is amazing it's small enough to fit under the dash in some applications .. I put mine under my seat so I can tune it easily
Pros: Price, size , look
Cons: Wish there were a bit more tuning options
It's a nice amp,clean power.The output watts are way over rated I am using the amp to power infinity kappa 6x8 speakers and i would say you would be lucky to get 50 watt RMS at 2 ohm.But that's plenty for me.
Pros: Small footprint,Nice clean natural power
Installed in a 2012 Sonata Turbo to power four Kenwood KFC-X173's. Plenty of power with clean sound. Small footprint is very nice.
Pros: Clean power / small footprint
I purchased this as a refurb. The packaging was pretty bad to be honest. Not on par with the normal packaging I have received from Crutchfield. It seems the item was shipped back from Kenwood to Crutchfield in a box with no peanuts or wrapping of any kind thus the amp was slamming around inside a box about 2-3 inches larger than the amp all the way around. When it was shipped to me that box was stuffed into a much larger box filled with peanuts. Still slamming around inside the smaller box... Very poor Packing by the Shipping and receiving department.
The item itself was a great product by a great Company. I paired this to run a pair of Polk DB461's and a pair of Infinity Kappa 93.11i's with a KAC-8105D that runs my 2 12" MTX JH45's. Superb value in size and features. The ability to run one set of RCA's in to power two separate pairs of speakers yet be able to use the pass filters = awesome. you can run 4 pairs of speakers on a 6 output headunit which is a super value if you want to run kicker area component speakers, door speakers and a sub.
The amp itself worked fine for a refurb I have no issues and you can't beat it for the price. Both my amps are Kenwood's and they are great bang for the buck. I would not hesitate to recommend the product.
Pros: Size is awesome a very very compact amp perfect for the two sets of cab speakers.
Cons: A little pricay brand new but that's why I went for the refurb. Hey can't beat that price with a stick.
Great amp. It sounds amazing and has plenty of power.
Pros: Easy connections.
This amp lives up to the Kenwood reputation of producing clean, distortion-free sound. It's small profile makes for an easy install beneath the seats, and the adjustment options are plentiful and effective. I've tried other products, but I always come back to Kenwood.
Pros: Clean sound, ample power, small size and ample adjust-ability.

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 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 4-ohm load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz, when applicable. 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 XR400-4 is rated at 75 Watts RMS x 4 channels with a 76 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006 compliant specifications:
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.
4-Channel Amp: The front and rear sections of the amplifier (labeled A and B) have independent gain and crossover controls.
Crossovers: The front and rear crossovers can be independently set to high-pass, low-pass, or turned off (full range). The crossover points are continuously variable with a selectable range, from 50-200 Hz or 2.5-10 kHz and the slope is 12dB per octave.
Aluminum Heat Sink: The aluminum heat sink increases the amplifier's heat dissipation efficiency, increasing the life of the amplifier.

price, size, reputation and ratings [ John Jan 10, 2016 ]
Great price for higher end item. Return policy good so hopefully no quality worries. [ Patrick Jan 10, 2016 ]
I'm running a 10" sub and 2- 6" speakers off mine without any problems. It gets warm but no warmer than any other amp I've used in the past. [ Randy Jan 29, 2015 ]
I' am running a pair of Kappa 693.11i's and a pair of Polk DB461's. Amp runs like a champ. It's a 4 way so not sure how you're gonna run 6 speakers off of it unless you're just using a set of components. [ christian Jan 29, 2015 ]
I do not know, I just connect 4 speaker, and it work find in my Ford Ranger [ Dan Jan 29, 2015 ]
I am running 8 off mine. I believe I ran 2 in series on each channel to give you 8 ohm per channel. [ Shaun Jan 29, 2015 ]
Would say yes depending on what wattage speakers your running and what ohms. Hope this helps [ Mathew Jan 29, 2015 ]
I run (4) OEM speakers in my truck. At moderate volumes, the amp runs pretty warm / borderline hot. I have no idea what the impedance values are for these stock speakers, and suspect they're between 4-6 ohm. Note - my front set are separate bass/tweeter combo, but I consider them a single unit. Thus far, I haven't experienced any issues - but my installation is open and there's nothing restricting cooling. For you to run a pair of drivers off a single output means you would expect to see impedance numbers drop to the range of 1-2 ohms (if attaching in parallel), and I would expect that to increase demands on the amp (read - run even hotter). However, I suspect you may also run into audio imaging and balance/fader related issues with such an hookup. [ STEVE Jan 29, 2015 ]
It's only a four channel amp. So you can run your doors and rears just fine and add your tweeters in with your front doors and it will word just fine as long as you don't exceed the amp specs [ Chase Jan 29, 2015 ]
yes absolutely, i'm running 2 6x8's in the front and 4 6x9's in the back of my car off this amplifier and you can push it hard for extended periods of time and it only gets a little bit warm. definitely worth the money [ ZACHARY Jan 29, 2015 ]
We don't have information on exactly how this is built internally so I cannot confirm exactly which way it works, but it would not make sense for the crossover to be applied after the amplification. Also, filtering the signal before its amplified is an active crossover. [ Paul Nov 09, 2015 ] Staff
