Cool running, lasts longer
The unique fin shape of the extruded aluminum heatsink helps pull heat away from the amp's interior, reducing distortion and extending the amp's life. An intelligent thermal management system continually monitors the temperature, saving your music from any interruptions due to overheating.

Crutchfield Customer Review (What's this?)

Performs exactly as expected. Does not have a gain knob but I knew that when I bought it. Fantastic performance for price.

Pros: Good Size

Cons: No Gain knob

Fits the bill.

Chris from Elk Grove, CA on 3/8/2017

Crutchfield Customer Review (What's this?)

Bought it open box and it works great. Matched it to a sub with a 300 rms rating and it seems to push it just fine. Actually hooked a multi-meter up to it and it hit 300 without being cranked all the way up.

Pros: Good power in a small package. Hardly heats up while in 4ohm. Powers my JL 10" just fine.

Cons: Cons: no remote and although you can adjust the sensitivity of the amp, there is no way to adjust the gain.

Another Great Kenwood Product

Crutchfield Customer Review (What's this?)

I have had this Kenwood amp for 2 weeks now & am very happy with it I have it powering a pair of Kenwood Excelon 12's in a ported box in my Charger Alpine Type R's in the door run bun a Kicker 2 channel amp & the sound is fantastic Once I set the gain to a little over a half & tuned my Sony dvd receiver (which I also bought with the amp from Cruthfield) I wars Very happy with my purchase This amp definitely gets the subs pounding if you are looking to run a pair of subs or even a single, you owe it to yourself to give this amp a look Don't be fooled by the small footprint.

Pros: Power, footprint, doesn't get very hot at long listening periods.

Cons: Not 1 thing I would by another without hesitation

Nick from Sparks, NV on 4/3/2016

Nothing is better than buying a product that not only has a small package ( the device) but also has big power output. Even though it's refurbished, the amplifier packs a punched paired with an Alpine Type S wired to 2 ohms.

Crutchfield Customer Review (What's this?)

The Kenwood Excelon X500 (factory refurb.) is a great valued product. It performs and looks like it is brand new and met the demands of the 12" subwoofer I wanted to install. If I need to make a future amplifier purchase, I will definitely look for another factory refurbished one.

Hlauver01 from Hampton Rhodes, VA on 9/24/2015

Crutchfield Customer Review (What's this?)

The kenwood X500-1 amplifier is a good bang for your buck. I purchased the amp factory refurbished, and it has run much better than my previous amp. There is no sound delay and doesn't get hot, and is very easy to install. All the connections fit 8 gauge wiring perfectly, and could fit bigger wire if needed. Everything is easily accessible, and can all be covered and hidden away with plastic end covers screwed in with an Alan wrench. The amp is a good purchase, and I would recommend it to anyone.



Simple, small, and powerful

Aaron from Florida on 9/21/2015

Arrylay from St. Louis, MO on 6/9/2014

This amp was out of stock when I ordered it and shipped only a few days later. Worth the wait. Delivers plenty of power to drive my subwoofer.

Pros: Affordable

Cons: No remote volume control, but my head unit has the adjustment anyway so no big deal.

Great deal!

Dz57 from st. Joseph, MI on 5/15/2014

Crutchfield Customer Review (What's this?)

Installed on my 03 Mini cooper. - Prefect size. - Lots of power. - Hooked up to Alpine SWA-10S4 BassLine Series 10" 4-ohm subwoofer. - Seems to run nice and cool. Over all, it does exactly what I wanted it to do. Intact it's got more power than what the sub woofer can handle. *highly recommended!

Pros: - Prefect size. - Lots of power. - Hooked up to Alpine SWA-10S4 BassLine Series 10" 4-ohm subwoofer. - Seems to run nice and cool.

Luis Z from San Diego, California on 4/18/2014

Crutchfield Customer Review (What's this?)

This Amp is great. I have it connected to 2 subs that output 400-RMS at 2 Ohm. The amp is 500-RMS at 2 Ohm, and is just perfect. I recommend this as an affordable amp that does the job.

Powerful amp at a great price. I ran 2 dvc 2 ohm phenix gold subs in an under seat truck box and they hit great. Won't win any competitions but if you want a nice clean sound at a great price. This is your amp.

Anonymous from Gering, NE on 8/29/2013

I bought a factory. Refurbished unit was told there was a scratch I could nit find,I am powering a JL W6V2 in 2 ohms load at12.8 volts set at about 155 hz +10 bass bost at at full power it bumps hard I love it an I have in many locations drove 8+ hours running it full out the hole trip never overheated or turned off just 100% EXCELON quality I love it going to add another X500-1 and another JL W6-v2

Pros: Super clean power low heat constant purformance

Cons: Hearing loss

Kenwood Excelon X500-1 - factory refurbished

JF from Norcross. GA on 8/15/2013

I bought the Factory Refurbished unit and I am very pleased with the product I got. Yeah, it has some scratches on the front that made it look a bit used, but it still has it's natural good looks. As far as features go, well there aren't any. You get the basics, a bass boost and a low pass filter. It's a simple design and for me, there is nothing wrong with that. That is actually part of the attraction I have for this amp - a simple design with few controls, compact and lightweight, great price, with certified power. Details are a little slim on the thermal shutdown function, but the amplifier should turn off to protect itself in case of overheating. I have this powering a sealed 8" subwoofer at 4 ohms, a very modest system for sure, but very enjoyable to listen to. I think this amp must be great for somebody who wants to add some low end impact in a simple configuration, without having to tweak too much. Performance is great in my setup. If you had a ported 2 ohm load, I'm certain this little amp could help rattle your car.

Pros: CEA 2006 certified power, compact, lightweight, simple attractive design, great price on refurb amp Thank you, Crutchfield for offering great deals on Kenwood products through factory refurbishment!

Cons: No subsonic filter, no speaker level input, no preamp output, no signal sensing turn-on - If you want any of these features you'll have to look elsewhere. Kenwood DOES offer these features in some of their other models, just not this one.

Great Sub Amp!

Shaggy from Hayden, ID on 6/11/2013

Crutchfield Customer Review (What's this?)

Great sub amp! Stays cool, small size, great price! I'm pushing a Kicker12' CVR and the gain is way low. Rattles my eye balls!

Pros: small size, stays cool, great price.

Cons: dumb little plates that need removal for install of wires.


Tony Ornelas from Frisco, Tx on 6/6/2013

Crutchfield Customer Review (What's this?)

Good bang for the buck, the first refurb unit I got was dead, but customer service got another unit to me right away. I paired this with a 4ohm excelon 10" subwoofer in my mustang gt and it sounds great... It really completes the sound system.

Pros: Cheap price, small footprint, low power consumption

Cons: Refurb unit arrived dead, I miss the sound from the older analog amps.

its tough

david from st.louis, mo on 5/12/2013

my be I got lucky... but I had it running two kicker comp 12"s and a alpine type r at the same time.... it didn't over heat at all... I know it wasn't enough power but im surprised it didn't fry r cook.... so imam see how tough it really is by running 3 type r's on it ... just to see... ps I know they r under powered n miss match.. but I was ballin on a budget.



Good sound, poor built-in boost

Anon from Ocean City, MD on 5/7/2013

Crutchfield Customer Review (What's this?)

Overall, this amp is great. It sounds great, was simple to put in, and really increased the quality of my bass. Built-in fuses is a nice feature. The dials on the back are easy to access and configure. The built-in bass boost goes from 0 to 18 dB, but it has issues (read cons for details). Looks sharp and has a nice profile. Doesn't have any problems with heat (so far) or for being on for extended periods of time (most I've had this thing pumping so far is 2.5 hours straight). Really makes my car bump.

Pros: Small size Easy installation Hasn't overheated in my trunk with 0 circulation in 90+ ºF weather. Have yet to test it above 100, but it hasn't gotten that hot yet. Sounds solid.

Cons: The built-in bass EQ doesn't boost all bass frequencies. It seems to boost up to 125-175KHz ish and then cut off. The mid bass is thus very quiet of you use the bass EQ. Quiet as if you had no boost on at all and that's not good. I had to use a mix of boosting at the headunit (which you're NOT supposed to do) and Bass EQ to get the mid-bass and high-bass sounding okay. Not enough to make me want to return the product. I don't know if this is a common problem, but if it isn't, would not buy again

Works flawlessly

Easy install, flawless quality from kenwood on this unit. Works perfectly and delivers clean power to my woofer.

Pros: Everything

Cons: Nothing


Noah from Salem, VA on 2/5/2013

this is my first amp ive ever owned, and i am completly blown away at how good it is!! ive been around a lot of other systems with poor sound quality and low power. i have a 12" JL W-O v3 in a ported box and i blow away any of my friends sound systems! i am about to upgrade to 2 JL W-O's running about 500 RMS and i cant wait to hear it! this Kenwood will have no problem suppling them. another amazing product from Kenwood.

Pros: Easy to use, looks great, stays at low temperature, even when running for awhile. not to mention the awesome sound quality.

Cons: not much customization for filters and things, and no remote bass knob. still a GREAT product though

Nice Amp!

SeanyD from Southern Oregon on 12/22/2012

Nice amp, compact, fits under my seat perfectly. I have had a lot of amps including JL 500/1, Alpine 1000, Alpine m450, and this amp is right there with these no problem. I pushes my 12" Rockford Fosgate WAY hard. Definitely get this amp.

Pros: Small, and solid.

Cons: None

Good little amp

Mike A from North Olmsted OH on 10/17/2012

Crutchfield Customer Review (What's this?)

Have it driving a used kicker CVR 10" wired up in 2 ohm in a sealed box in the trunk of my 2011 fusion. When cranked up it rattles my license plate on the out side of my trunk. Other reviews of kenwood amps people complain about them burning out after 6 months to a year, well that is because they don't set the gain properly. If you set the gain correctly then they are great little amps.

Pros: Very compact for its output.

Cons: None that I have noticed

Clean and good looking

Daren from Spokane WA on 9/5/2012

Crutchfield Customer Review (What's this?)

This amp is way clean and it has plenty of power. It is powering a Rockford 12" and I can only ramp the gain 1/2 way. I didnt need the bass boost either, as it is booming the neighborhood just fine without it. I could easily add another 12", and this amp wouldnt bat an eye. Love the clean look of the amp too.

Pros: small, and loud

Cons: None

Powerful amp compact size.

BuryYourDiamonds from Wethersfield, CT on 8/12/2012

Crutchfield Customer Review (What's this?)

I have this amp hooked up to 2 12" JBL GT-5 subs. I wired both subs in parallel so the amp is pushing out 500 watts RMS @ 2 ohms and I have to say WOWWW. Those JBLs pound so hard now that it makes my rear view mirror pretty much useless and i can feel the bass rattling my brain lolll and thats without turning up the amps bass boost all the way i couldnt imagine how hard they would pound if i did. This amp def has tremendous power and its very compact so it can fit pretty much anywhere in your vehicle, i just so happen to drill it down to the top of the sub box cuz it looks pretty cool there lol. Now besides its power and compact size, crutchfield offers a free 4 gauge wiring kit with it thatll save you $80 which is the cherry on top of the deal. I would def reccomend this amp to anyone who wants to add raw power to their subs and wants a sleek and compact amp doing it.

Pros: POWER, compact size, and a free wiring kit with it sweet freakin deal!

Cons: none


VictorM from Lakewood Ranch, FL on 7/7/2012

Crutchfield Customer Review (What's this?)

Great amp, small compact. I have it hooked up to a pair of MTX Terminators Sealed Box 400 RMS @ 2ohm. This amp can seriously move them no problem. I do recommend this amp to anybody.

Pros: Small compact looks good

Cons: No remote bass controller


Hands-on research

Product Research


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 X500-1 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 0.5% THD, 14.4 volts)
  • Signal to Noise Ratio: 100 dB (at rated power)

Mono-Power Amp Design: The Kenwood X500-1 is designed with specific features to power your subwoofers 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 X500-1 has a built-in 24 dB/octave low-pass filter, 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.

Aluminum Heat Sink: The aluminum heat sink increases the amplifier's heat dissipation efficiency, increasing the life of the amplifier.


  • Input Sensitivity: 200mV-5V
  • 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 0.54" wide
  • Ground: screw terminal; accommodates spade connector up to 0.54" 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

4 gauge is perfect for it. I don't have any overheating with the Amp. [ KENNETH  Mar 25, 2015 ]
I use 8 gauge on mine with no problem! [ Harrison  Mar 25, 2015 ]
Honestly, that's not necessary. I have two Amps on my mini cooper next to each other. About 2 inches apart. I used 10 gauge wiring on both. No excessive heat. Been running them for over a year now. The Kenwood X500-1Mono Amp is running a 10 inch sub. It kicks really good. More than enough for my Mini anyways. [ DAVID  Mar 25, 2015 ]
Yeah. I'm using 8 gauge, it's a little smaller than I should be using but it's worked for the last 2 years [ evan  Mar 25, 2015 ]
What do you mean by reset? [ Harrison  Jan 12, 2015 ]
Never had to reset it [ DARREN  Jan 12, 2015 ]
Turn all the knobs to the left? [ DUSTIN  Jan 12, 2015 ]
Reset? These amps don't hold any memory or setting other than the small dials on the ends. Blessings [ IGOR  Jan 12, 2015 ]
It doesn't have enough enough power for that sub, you never want to under power a sub, look for something with 750 watts RMS, always go a little more then what you need [ Timothy  Jan 02, 2015 ]
Yes it can, I'm currently using it to push an Infinity 12" and it works beautifully. It's very compact as well which is nice. As for wiring, i didn't do anything different than I would normally do. Just wire it like it requires aND you should be good. [ KYLE  Jan 02, 2015 ]
Thanks for your question. For information on selecting the best amp for your system 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. [ Krissy  Jun 11, 2014 ]  Staff
If you mean combine wattage like wire them both to the same sub. No. It doesn't work like that. If you have a DVC(dual voice coil) sub and 2 of the same amp and know what your doing. Yes you can put one amp per voice coil but two different amps, things will break and you will be sad. [ evan  May 14, 2014 ]
Yes [ GRIFFIN  Feb 24, 2014 ]
Yes it does require a remote wire, if it didn't have one it would draw too much power from your battery when your car wasn't running causing your battery to be drained. [ Robby  Feb 19, 2014 ]
Yes, I think all amps require one! If your RCA cables don't have a wire built in, just run one with those or the 12 volt power wire. [ MATTHEW  Feb 19, 2014 ]
Yes. Just a simple single wire to and ignition source or the blue remote wire on an after market stereo. [ JASON  Feb 19, 2014 ]
There are many variables with audio systems so that is why the amp has some of these adjustments. What works in one car may not work as good in another. The lpf depends on your speaker, I generally go with a lower setting, 90 or hz or lower. Sensitivity will vary with head unit. I like to get the system set up without the sub first, then turn it on and try to bring it in line with the rest of the system. You can try sensitivity at the half way point and go from there but in my vehicle I had to turn it down low! I enjoy tuning my system so try it out with different tunes and try to have fun listening to music. Sorry for such a long response but I hope it helps and I hope you enjoy your new system. Don't be afraid to change settings and listen again! [ MATTHEW  Dec 30, 2013 ]
