Our take on the Kenwood Excelon XR600-1

Kenwood's Excelon XR600-1 mono subwoofer amplifier adds power and punch to your car's subwoofer system, as it powers your sub with up to 600 watts RMS. The XR600-1 can fit in many different places in your car because of its incredibly low profile — it's under 1-1/2" tall. Amazing.

Super-slim profile, big-time power

Kenwood's Excelon XR600-1 mono subwoofer amplifier adds power and punch to your car's subwoofer system, as it powers your sub with up to 600 watts RMS. The XR600-1 can fit in many different places in your car because of its incredibly low profile — it's under 1-1/2" tall. Amazing.

Designed for optimum efficiency

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.

Controls for the best bass

This no-nonsense amplifier features a low-pass filter that sends the correct frequencies to your sub so it'll  play efficiently and sound its best. The amp also includes an adjustable bass boost that adds some low-end punch when you want it.

Great amp, lots of power for its compact size. Gets hot quickly but after installing fans it stays at a good temperature.

Packs a Punch!!

Crutchfield Customer Review (What's this?)

Purchased this amp after reading threads and good reviews about this amp! Crutchfield had a great refurbished price and decided on this amp to power two 10" CT Sounds Thermo series subs. I went more for SQ rather than SPL and I tell you, this amp can handle the load and produce some good quality bass from those CTS subs. My first Kenwood amp and may go for more in the near future!! BTW...if you're adding an amp to your OEM radio, Audiocontrol LC2 is the only way to go and stay away from those cheap converters out there. Pay the and get it done right the first time!! Crutchfield will assist you in all your car audio needs!!

Pros: Compact Design Powerful

Cons: Nothing yet

very imprsssive!!!

Carl from Shrewsbury, MA on 8/8/2017

Wow! Where do I start! This amp is mint!! I have it powering an Alpine 12 type R (ported box) and it matches it perfectly!! Nice clean bass with amazing spl and loudness. I have the matching 4 channel (XR400-4) and they look as good as they sound! Very impressive!!! You will not be disappointed.

Pros: Everything

Cons: None

Kenwood XR-600-1 (Refurbished)

Dave from New York on 5/20/2017

Crutchfield Customer Review (What's this?)

Bought the refurbished version of this product. Had no problems for the first 90 days, worked well with my 10" Memphis sub. Two weeks after the warranty was out (90 day warranty) the amp stopped functioning. The problem it was refurbished for (faulty ground connection at the amp) was now back. Crutchfield said they couldn't help and now waiting for Kenwood to get back to me. Also the screws for all the wires that connect to the amp are three different sized allen wrenches and there is a plate covering them all that needs two screws to come off before checking connections. Pain in the butt if you want to trouble shoot problems.

Pros: When it works it's small, very responsive and hits hard.

Cons: Three different allen wrench sizes make plus a protective plate on the back make it hard to trouble shoot connection issues.

Great product

One of the best amps ever!!!

Pros: All great.

Cons: None

Very Pleased

Brad from Commerce, GA on 7/3/2016

Installed this amp to power a Kicker 40TCWRT122 sub and does it ever do it nicely. With the gains only set to 60% drives this 12" sub very well. I had an Infinity BassLink before upgrading with this amp and the Kicker 40TCWRT122. This new setup is not even in the same league. I listen to different kinds of music and it sounds great with them all. Very happy with the new bass!

Pros: Power Clarity Size Features

Cons: None

Crisp Power, easy adjustments

GRHowell from Palmer, AK on 5/20/2016

Crutchfield Customer Review (What's this?)

Very easy to adjust the power of this amp. Followed the set-up advice listed on Crutchfield, and the sound really came in full and complete.

Pros: Small size, easy use, bang for the buck

Cons: Subwoofer specific

Crutchfield Customer Review (What's this?)

Easy plug in installation while replacing existing amp . Quick to adjust and dial in. Convenient compact size for ease of location. I miss the cooling fan from the prior amp but so far no problems with heat build up. Great bang for the buck!

Pros: compact size, ease of location and hook up

Cons: no cooling fan


bobbo from Warwick, R.I on 2/14/2016

Crutchfield Customer Review (What's this?)

Great little amp. Was very skeptical when I seen the actual size in person but after installing it in line with a audio control 6xs and hooked up to a pair of Boston acoustic g2 12's I was blown away with the sound quality and power. Also very stable at high volume and does not get overly hot

Pros: Very small foot print Super simple installation and set up Very stable and efficient Can't beat the refurbished price

Cons: None so far

Awesome amp!

Andrew from Ann Arbor, Mi on 2/3/2016

Crutchfield Customer Review (What's this?)

This is a fantastic ampilifier! At first it confused me having 1 set of rca in, and 2 sets of speaker outs, but it works amazing. I have this amp powering two 4 ohm subs (shallow mount rockfords) and it does it like a champ! I am however disappointed by the screws for the speaker outs, one screw head (the part that the alan wrench goes in) had stripped as I was trying to loosen it to put 1 sub per set of speaker outs. Since 2 wires were already in I was able to just cut one off, but if I ever use this for another set up I have to make sure to leave myself plenty of wire so I can connect that terminal to another speaker/sub. Over very pleased with it, expecially for the price from the referbished model! The things brand new basically! Not even a scratch!

Pros: Small/compact Easy dial adjustments Very clean look with terminal screw covers Delivers power equally to subs

Cons: Screws seem cheap

Excellon XR600-1

Jimmy from Puerto Rico on 7/20/2015

Crutchfield Customer Review (What's this?)

Great amplifier for a 10 or 12 inch sub-woofer. I bought this amplifier because of the small size so I could fit it under my pickup truck seat. Don't be fooled by the size, it really move a sub woofer to get full rich bass in your ride.

Pros: Compact Size and powerful sound. Easy to Install.

Cons: None

Minnesota from Indiana on 6/22/2015

Great, small form-factor amp. Powers my 2-ohm, Kicker CompS subwoofer perfectly. I did have to trim my 1-ought wire to fit, but that was expected.



best Lil amp

gewber from lapeer michigan on 4/24/2015

Best amp I've owned yet. I have my xr600-1 hooked up to an american bass xo 1544. And wow. That's all I can say. Other than it makes my trailblazer rattle and flex all over.

Pros: Too many to list.

Cons: None

small amp with a big power punch

p. kidd from richmond, va on 7/15/2014

I purchase only kenwood amps for the past 18 years. I ran this amp to my P3 and I can't believe this little amp does so much.

Sounds great I have this amp on a rockford t1 12



The little amp that could!

Kawizx9r from Monterey Bay, CA on 3/2/2013

I never submit reviews however that's changed now with my new Kenwood Excelon XR600-1. Just purchased it along with a 10" JL Audio W3 subwoofer and together they sound great! I was a bit skeptical at first considering I've only owned one Kenwood amp in the past but this little thing puts out power! It took some time dialing everything in but once that was done, I was able to do a proper comparison against my retired JL Audio 500/1 slash amp. The two on the same subwoofer sounded nearly identical with the same 'oomph' and authority you'd expect from the slash amp.

Pros: Size Power

Cons: Price? I only purchased one. No sub-sonic filter


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 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 (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 XR600-1 is rated at 400 Watts RMS x 1 channel with a 78 dBA signal to noise ratio.

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

  • Power: 600 watts x 1-channel (into 2Ω at 100 Hz, with no more than 1% THD, 14.4 volts)
  • Signal to Noise Ratio: 100 dB (at rated power)

Mono-Power Amp Design: The Kenwood XR600-1 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 XR600-1 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 preamp inputs
  • Preamp Output: one pair of pass-through RCA preamp outputs; used to easily connect a second amplifier to the same signal feeding the XR600-1's input
  • Power: set screw terminal; accommodates bare wire up to 4-gauge
  • Ground: set screw terminal; accommodates bare wire up to 4-gauge
  • Remote Turn-on: set screw terminal; accommodates bare wire up to 10-gauge
  • Speaker Output: two pair of set screw terminals; accommodate bare wire up to 10-gauge; the two outputs are internally wired in parallel, making it easy to connect two subwoofers
  • Fuses: three 30 amp mini blade fuses
