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

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.

Perfect Fit

Written By Paco, North Miami,FL on Wednesday, February 08, 2012
 
Perfect fit. I love it. I use it everyday. I ordered the 6ft plug to go with it so my daughter can plug her dvd player to my sound system. I use it with my smart phone and ipod. Sounds clear. I'm happy I didn't have to buy a new radio. I love my radio.

Alpine KCA-121B Auxiliary Input Adapter

Written By B.A., Seattle, Wa on Sunday, January 30, 2011
 
Pretty straight forward, and simple. Did what it advertised, can't ask much more. Could be
cheaper, but I suppose you get what you pay for.

You get what you see!

Written By Vik, Long Beach, CA on Thursday, October 01, 2009
 
You get what you see explains all!
The cable on Crutchfield website were cheapest among all the competitor went I bought from them. They were brand new, worked absolutely fine after installation.
I do a lot of online shopping and my experience is not always pleasant with online shopping site but I will highly recommend this Crutchfield website based on my past experience.
Keep up the good work guys!

Excellent

Written By 245Dad, Edmonds, WA on Monday, January 26, 2009
 
Used this with my Alpine CDA-9884. Works perfect. The head unit came with an iPod adapter that allows me to charge and control my iPod with the head unit itself. The KCA-121B also gives me the option (with an adapter cable) to control my iPod from the iPod itself (although it won't charge at the same time). Great when you have a passenger who wants to "drive" the music without trying to learn how to use the head unit. Works flawlessly.

AWESOME Cable

Written By coolio1729, Kentucky on Friday, November 28, 2008
 
The Alpine auxiliary input adapter cable is a 5-star purchase. My uses for it are twofold - cell phone and iPod. I decided to also purchase a 6 foot generic 3.5mm mini-stereo male to two RCA male speaker cable. I connected the female RCA ends of the auxiliary input adapter to the male RCAs of the speaker cable. Now, I use the 3.5mm male plug to connect to my cell phone or iPod.

I recently upgraded my cell phone to the new HTC Touch Pro. After downloading the latest audio/video podcast, I connected the phone to the 3.5mm male plug (through a separate HTC adapter) and bingo, all of the audio was broadcast through the stereo. This capability is killer and the sound is great!

I also use the 3.5mm plug to connect to my iPod shuffle. Again, the sound is great! Any audio device that has a headphone jack can be connected to the stereo with the auxiliary input adapter and additional cable that I mentioned above.

In sum, this auxiliary input adapter expands the capability of your Alpine radio. It was also easy to install.

For Sat Radio and Alpine head unit

Written By Christopher, Plano, TX on Monday, September 08, 2008
 
This was a must have if you want to use your aux input on the back of the head unit. Quick to install and gave mush more flexibility to my jeep.
