Great Piece -KNOW WHAT YOU'RE BUYING PLEASE

Written By SlyWhite, Oklahoma City on Sunday, March 18, 2012

Kind of confused by the first two reviews. This item has one Ai-net input (from radio) which provides two Ai-Net outputs. Of course you can only listen to one at a time. Sounds like the first two guys who provided poor reviews were trying to get into a rear entertainment system on the cheap....This doesn't do that, and the description doesn't say it does. You have to pay for a unit that provides you multi-zone entertainment. Good piece from Alpine as always.

Well... okay

Written By Keaton, Norman, Oklahoma on Tuesday, September 09, 2008

Problem: you need to hook up more than one accessory to the head unit.
Solution: this product... right?

Well, you can hook them up, but only one works at a time, which may work for you, but not for me. Here's why:

I wanted to hook up my iPod and a Bluetooth adapter for my phone. With this product, I can hook it up, but I have to switch sources to take a phone call and by the time I tell the person to hang on and start changing things, the phone call gets dropped in the switch-er-oo.

Bottom line, Alpine dropped the ball on this setup. You'll spend more and more money until you have to have a trailer to carry all the add-on boxes for the unit.

Only adds one Ai-net input?! Shame on Alpine

Written By Mike, Phoenix, AZ on Saturday, August 23, 2008

Alpine markets its head units as being able to seemlessly switch from one add-on input to another, but they simply don't deliver on the promise. If you want to add, for example, a CD changer, an iPod adapter, a USB adapter and bluetooth, you have to pick just 1, because all Alpine decks only have one Ai-net input, and NONE of the Alpine add-on units have Ai-net pass-through connections. Okay, so maybe Alpine sells a add-on with multiple connections---enter the KCA-410c. Buuuuuuuttttttt, Alpine blows it there too. First off, this thing's price, which is simply too much for what amounts to nothing more than an A/B switch, but the real problem is that it only expands the Ai-net inputs by 1. Gee, great, Alpine makes all of these great add-ons, but you can only use 2 of them at a time, and that's only if you pop $ for this adapter. Am I supposed to fork out another $ to add a third add-on (and that's on top of the price of the add-on), while cluttering up my car with yet another one of these units? If I want 4, I have to spend a lot of $ for 3 of these? That's pretty ridiculous, and I just don't understand how Alpine doesn't realize that this is a huge problem. This really takes a product line with huge potential and makes it simply fail to cross the finish line.

Simply..............awesome!

Crutchfield Customer Review (What's this?)

First of all, GREAT SERVICE from Crutchfield!!!! I hunted this unit for months now. Tried Worst Buy and Tweeter/Sound Advice and was told it was a "special order". After being patient, for months, i called Crutchfield and ordered this unit. 2 DAYS later, i recieved it! I have the IVA-D310, KCA-420i, SIR-ALP1 and the CHA-S634. Because of the ONE Ai-Net connector on the unit, i was left to choose between the iPod/Sat radio OR CD changer. Naturally I chose the iPod/Sat radio. The KCA-410C lets me connect ALL units together and i still have 2 AUX to boot. 3 simple "clicks" of the cable and i was good to go. I will order from Crutchfield from now on. :)

Great Product But Shame On Alpine For Not Making Aux In Standard

Written By Keith, Ithaca, Michigan on Saturday, September 17, 2005

Crutchfield Customer Review (What's this?)

First off let me say that this box does everything it's supposed to do. I have my Nomad Zen Xtra hooked up to one of the two auxiliary inputs. I was able to adjust the kca-410c so the volume when on auxiliary matched the volume when I changed to XM or CD. With The Zen Xtra I don't know if I'll be adding a CD Changer but with the KCA-410C I know I can if I want to. My only problem is with Alpine the company itself. Why did I have to spend $150 on top of the $450 I spent for my CDA-9855 deck to have an auxiliary input?
The only Alpine unit that comes with it standard is the CDA-9845 that sells for only $179, but then they took away sat ready. If Clarion, Kenwood, JVC, Panasonic & Sony can offer auxiliary in, sat ready and cd changer as standard on their decks why can't Alpine & Pioneer.
I love my Alpine CDA-9855 but if I'd done a little more research I'd have a Kenwood now.

Add your iPod and a cd changer

Written By TR, Westlake Village, CA on Tuesday, March 08, 2005

Add this to your Ai-net head unit and you can add up to two cd changers or two ipods. I hooked this up with my ipod and an Alpine CHA-S634 6 disc cd changer. Great sound quality and works perfectly.

great product

Written By gandallf7, illinois on Monday, February 14, 2005

this is a wonderful product for anyone who has an ipod and wants to listen to it in their car. the only down side was that i had to buy another headunit than the factory one in my car. but once purchasing it i was greatly suprised at the quality of sound that came out of the reciever. i was finaly glad to have great sound and something that would charge my ipod as i drove. i recomend this for anyone who already has an alpine headunit that is compatable and also for anyone looking this combo is something to buy.
