Our take on the Alpine KCA-121B Auxiliary Input Adapter

by Charlie Pastorfield
Alpine Authorized Online Dealer

The KCA-121B auxiliary input adapter allows you to convert the Ai-Net changer port on your Alpine stereo into an audio auxiliary input. One end of the adapter connects to your changer port, and the other end gives you a pair of female RCA jacks. Once connected, you can select the AUX source on your stereo and utilize the Bass Engine® sound-shaping functions to personalize the playback. 1-year warranty.

Note: When using the KCA-121B, a CD changer cannot be connected to the stereo; the KCA-801B auxiliary input adapter allows you to connect an auxiliary source and an Ai-NET changer to the stereo. The KCA-410C Versatile-Link™ Terminal allows you to feed audio from up to two auxiliary sources and two Ai-NET CD changers to the stereo.

Alpine KCA-121B Auxiliary Input Adapter

Written By memyself, CA on Sunday, October 22, 2006
 
I just thought I should add this little note, I just learned myself, since this pink/black lead is really intendede to MUTE your stereo when getting a phonecall or something of this nature, your stereo is DEFAULT set to 'MUTE ON' in the menu, so you need to set this to OFF after that it works like a charm on my late 90's Alpine unit!! Check your manual how to do this!

Bottom line if you have an AINET input AND a PINK/BLACK lead you should be good to go!

Works like a charm!

Written By BiggLou55, Nashville, TN on Tuesday, February 14, 2006
 
I got this for my CDA-7894 in the hopes that it would save me from having to upgrade to a new head unit to support my iPod. Well, it works GREAT!!... After connecting everything up, all I had to do was go into the menu and active the Aux port. I also have a Belkin power adapter with an audio jack (w/ volume control) built in. All I have to do is hock the power adapter into the iPod and it's on! I suggest this for anyone who has an older Alpine head unit and want to connect their iPod or other Aux device. All that is required is a 2001+ Alpine with an Ai-net connection on the back (CDA series)...

Universal connection for your Alpine received

Written By doru, Redmond, WA on Saturday, January 21, 2006
Crutchfield Customer Review (What's this?)
 
I'm using this with CDA-9847. I just went and bought wall mount audio RCA connectors ($2 each). I made two holes in the trim right above the cigarett lighter (I own a Camry 97) and mounted the RCA connectors. I route an RCA cable from the connectors to the Alpine KCA-121B and now I can connect any device that I want. The connectors are oriented downward at 45 degrees, so they are easy to access but not looking intrusive. Now I can connect my MP3 player and my notebook (for my kid in the back, to have good sound not only good picture).

Alpine Ainet to RCA

Written By James, Rolla, Mo on Monday, December 12, 2005
 
I bought one of these for my CDA9851, and it was a breeze to install and set up. This cheap cable is the reason I bought the 9851, Sony wanted nearly $100 to hook up my laptop to an RCA connection, so wth my new car, I pulled my old sony receiver, and put it in a box. With Monster Cable RCA to mini jack connector, the sound quality is perfect. Another thing that impressed me, is you see what look like covers over the RCA connections in the picture, but they are actually boots to better insulate your connection.

Must have Versitile Link or this work-around if unit is pre-2001

Written By David, Dublin, CA on Wednesday, November 30, 2005
Crutchfield Customer Review (What's this?)
 
This part works as long as your reciever is 2001+. It did not work for me and I called alpine. It turns out that you need to have Versitile Link which is on the Ai-net products after 2001. I had a 1999 CDA-D852. The good news is that there is a work around using the audio interrupt lead (pink/black) on the wiring harness. Pass this lead through a switch and ground the other side. When this lead is grounded it tells the reciever to listen to the signal coming from the Ai-net connector. Once you have this hooked up you just flip the switch to listen to your aux. device.

Works like a Charm

Written By Mike, Leesburg, VA on Thursday, November 10, 2005
Crutchfield Customer Review (What's this?)
 
After buying/using a FM Digital Transmitter for my Ipod, I was thinking I'd be set. I was with the auto charger feature but the radio part didn't statisfy me enough with static noise I was facing. I didn't know I could use such a cheap Alpine cable to use with my Ipod. I bought a Belkin RCA to Portable Audio cable to attach to the Ipod. So far I am using the cable with a 2001 Alpine CDA-7977 w/Ai-Net, I recommend this way versus the radio transmitter.

Excellent

Written By Jason, Chicago, IL on Monday, September 05, 2005
Crutchfield Customer Review (What's this?)
 
I bought this product to use for my ipod and the quality is outstanding. I would recommend combining this with the Monster iCable for iPod if you're really obsessed with quality. There is absolutely no static and the sound is crystal clear. Do not go cheap and save a couple of bucks, you will be very disappointed. You might as well spend the extra cash and get everything right the first time.

I bought this for my 2004 Alpine and it's awesome. I think even if you have a 2005, why get that expensive module? This took me 5 mins to hook up and it's the cheapest best way to hook up your ipod. Plus it takes forever to scroll the songs on the Alpine screen. Good buy! always from Alpine.

Don't Be Fooled

Written By Frank, Roanoke, Va on Saturday, April 16, 2005
Crutchfield Customer Review (What's this?)
 
I first bought a off brand and was not satisfied with the fit or performance. One channel did not work. If you are thinking of going with a outside source instead of a Alpine part, just to save a buck or two, forget it. This piece worked perfectly. I use it for my Skyfi. One other tip. Use the best interconnects you can afford. It does make a differance in sound quality.

Works Like It's Supposed To

Written By Curtis, Milwaukee, WI on Monday, March 21, 2005
 
I got this so I could hook up my iPod to my CDA-9883 and it works like a charm. The only thing I suggest is buying a high quality audio cable to use with whatever type of player you are hooking up. I went cheap and got a low quality cable. It sounds nice, except that at higher volume levels you hear a lot of white noise in between songs or during quiter parts of songs. That being said, there is no reason not to buy this, and I think it is a better solution for iPod users becasue you can use your iPod controls.
