This CA-C1AUX adapter converts the changer control plug on the back of most recent (1999 and later) Kenwood changer-controlling receivers into an auxiliary input. The 10" cable has the 13-pin male DIN connector at one end and female RCA plugs at the other (allowing you to connect an MP3 player, for example). Warranty: 30 days.

Note: When this adapter is used, you can't connect a CD changer to the Kenwood receiver. You can't connect this adapter to the pass-through changer port on a Kenwood SIRIUS tuner.

Exactly As Advertised

Written By RoyH, Montgomery Village, MD on Saturday, May 25, 2013

Crutchfield Customer Review (What's this?)

This makes adding a line in device (satellite, cell phone, etc.) easy. The sound is so much better than with the FM transmitter solution. For my specific install, the orientation of the plug was a little tricky, but that is more to do with the stereo install and not this unit.

Pros: Connected easily and securely. Seems very well constructed.

Cons: Orientation can be a trick for some tight stereo installs, but nothing hard to overcome.

The quality of this was very good. It works great with a Zune. The only minor
problem was that the 90 degree bend on the Kenwood round jack went the wrong
direction sending the cable up slightly above the top of the tuner. Good part, value

In 2011 I installed a brand new Kenwood KDC-516S headunit that was laying around
the garage since 2000. That was long before iPods or any of the smart phones.
This adapter with another cable allows me to plug in my Android to have a
completely current setup.

This is a great option for those who have an AUX input but no USB. i bought an ipod
shuffle to use and once i got it i plugged it in and all i can say is "WOW". i was very
impressed with the sound quality.

Excellent product. It was easy to install and I can now plug my satellite radio directly to my boat's stereo. I recommend this product highly.

This adapter works great, it is compatible with my old (circa 1998) KRC-3006 head unit in place of the CD changer. Makes Ipod listening a breeze. Money well spent.

Installed in my 2000 Honda Civic with my Kenwood KDC-MPV619 in under 30 minutes. I do hear an audible pop whenever I connect my iPod.

Great product. I used an FM transmitter for playing my mp3 player, and the sound quality wasn't too good. No highs and to much lows. When I added this to my head deck. It was music to my ears. :D Two thumbs up.

Great, but...

Written By Dave, Savannah, GA on Thursday, January 29, 2009

Crutchfield Customer Review (What's this?)

Functionally, this works great. Unfortunately, the connector is oriented upwards when attached to the receiver. This causes space problems behind the receiver, especially if space is tight already. There is no room for the tight bend the cable must make right away, since it has to bend 90 degrees to point out behind the receiver, then another bend to point in whatever direction your installation requires. Make sure it isn't riding against anything that moves or it'll chafe away the insulation!

Great for "Line In" Electronics

Written By Charlotte, CO on Saturday, April 26, 2008

Crutchfield Customer Review (What's this?)

I tried to use this to connect my circa 1995 Sony 10 disc changer directly to
a Kenwood KDC-MP338 rather than running it through the old FM
transmitter. Unfortunately, the changer must have a small amplifier in it
because the input signal was severely over-amplified, which greatly
distorted the sound.

This is an awsome way to add an auxiliary input to the rear of a Kenwood
stereo, but just make sure that what you're sending into the stereo is at a
standard "line in" amplitude (i.e. mp3 players, etc.)

I bought this adapter so I could listen to my XM radio through the CD changer input in my works perfectly and has alot better sound quality than with the dreaded built in FM modulator...thanks Crutchfield!

Great product

Written By Mike, St. Cloud, FL on Monday, August 21, 2006

What a great cable!! I bought it to use for hooking up my iPod in my car and it sounds awesome. If you are trying to figure out which option is best for connecting an mp3 player, this is it! It's much cheaper than buying a whole new head unit and definitely more reliable and better audio quality than an FM transmitter. Go with this option! It's so easy and cheap and you get great results!

I'm getting good clean sound from this adapter. The only complaint I had was that it does not fit very snug into the outlet on the back of my head unit. It seems like it could come loose after time fairly easily. Still a must have for any unit that doesn't have an aux input built in.

Serves its purpose well

Crutchfield Customer Review (What's this?)

I used this along with an Arista 18-3190 RCA-to-Stereo cable to connect my Creative Zen Sleek to the Kenwood stereo I installed in my '96 Jetta. With just a little effort I now have hundreds of songs at my finger tip. The only downside is when I compared songs from the MP3 connection to their parent CDs, the quality was marginally lower, but still barely noticeable unless direct comparison. Overall a very reasonable way to have your MP3s on the road with you.

This item works perfectly. I use this with my iPod and the sound is perfect with no static like radio transmitters (e.g. iTrip) usually have. The angle of the plug did not cause any problems in my vehicle. My local car audio store charged $10 more for this item.

This was a perfect adapter to convert my changer input to an aux input so I could connect my iPOD to my headunit. My eXcelon headunit has a 6" lead for the changer cable, so I had no problems with the design of the adapter.

So easy Koko the ape could do it.

Crutchfield Customer Review (What's this?)

What a great cable, the only problem was the angle of the connector. I was installing this into my wife's 1998 Corrolla so we can hook an I-pod to the head unit.We had to wiggle this and wiggle that to slide the head unit back into place because of some small interference with the A/C ducts behind the stereo.Other than that very easy.Were rockin with the I-pod now.

Works As Planned

Written By Bill, Sterling, VA on Sunday, March 26, 2006

I agree with the other reviewers regarding the direction the cable exits the connector. Just plain dumb. That having been said, this cable works perfectly with the Hyundai/Kenwood head unit installed as OE in the 2004 Hyundai Elantra GT (and only the GT model). My two teenage daughters love playing their iPods through the factory radio!

This product saved me about $200. I almost bought a new head unit with an auxillary input in it. But come to find out this product works with my Kenwood KDC - MP425. Installation is straight forward but I'd have to agree the design should be better. Also I couldn't find this product anywhere else. Only at CRUTCHFIELD.COM. Thanks guys.

Inexpensive solution for your iPod/MP3 player

Written By Jason, Los Alamos, NM on Thursday, June 30, 2005

Crutchfield Customer Review (What's this?)

I have a Kenwood DPX-MP4030 double-DIN receiver and wanted to connect my iPod to the receiver for better sound quality. For over a year I put up with the poor sound qualiy of an FM transmitter. This cheap solution is perfect for adding a basic aux. input to your Kenwood receiver. I almost purchased the Kenwood KCA-iP500 but read a review for that product that mentioned this CA-C1AUX device. I was very pleased to find this as I have a plug-and-play Sirius satellite radio receiver that I can now connect through my Kenwood receiver as well as my iPod. Not to mention the CA-C1AUX was MUCH cheaper!
Installation was easy and straight-forward. The pig-tail on this adapter is perhaps a bit short but I was able to find a place in my dash for it to stick out.

Slap the Engineers

Written By Bryan, Virginia on Monday, February 28, 2005

It works! What more do you want? Well, it could have been designed a little better. Install was easy, except getting the wiring to fit back behind the dash. Wire for the aux input comes up from the changer plug in the back of the receiver (KDC-MPV622 in my case) when it would be better designed to go to the left of the bottom. Easy use and only setup is plugging it in. Had some issues with contact to the heat sink on the back of the receiver. Fixed with some electrical tape and routing of the wires, but just not the best design in the world.

Hands-on research

Download owner's manual

  • 10" Auxiliary Input adapter for Kenwood head units (with a round 13-pin male DIN on one end and stereo female RCA plugs on the other)
  • Instruction sheet

Product Research


Compatibility: This adapter should only be used with changer control head units that have the adapter listed as an accessory. The adapter is not compatible with pre-1999 head units. This cannot be used with the pass-through port on Kenwood Sirius tuners. If you have a Kenwood Sirius tuner and want AUX in capability, a Kenwood KCA-S220A will be required; the KCA-S220A is a two changer switch with a stereo RCA auxiliary input.

Plugs into Head Unit CD Changer Control Connector: When the CA-C1AUX adapter is used, you cannot connect a CD changer to the head unit (the CA-C1AUX plugs into the changer control DIN connection on the head unit).

Inputs and Cable Length: The female RCA inputs are at the end of a 10" cable; they are coded red (for right) and white (for left).
