Precision Interface Electronics designed the ALP/M-RCA adapter cable to allow you to connect one auxiliary audio source (MP3 player, iPod, DVD player, etc.) to any Alpine Versatile-Link™-ready M-bus head unit (the adapter will be listed as an accessory for compatible receivers). Once connected, you can select the AUX source on your receiver to permit playback of an outboard audio source through your Alpine receiver.

Important Note: When the ALP/M-RCA cable is used, a CD changer cannot be connected to the receiver. Warranty: 1 year.

Crutchfield Customer Review (What's this?)

To my surprise this item, along with the Scosche I6RCA35A, is all i needed for my 10 year old deck to be ipod compatible. Kudos to the very knowledgeable Crutchfield staff for providing me step by step information as to what i needed, how to switch on the Aux option on the outdated deck, and most importantly, save me $ in not having to replace the existing deck.

Works perfectly

Crutchfield Customer Review (What's this?)

This is just what I needed to breathe new life into my 10 year-old Alpine unit.
Initially I bought the wrong type of adapter. The newer Alpine units use a
different type of connector (Ai-Net), so I got this one instead (8-pin M-Bus)
and it works as intended. The sound quality is very good and I don't have to
deal with CDs any more.

As previously mentioned, there is an "Auxiliary" setting which must be turned on
to enable the input.

High quality, not too short for reaching behind the unit, good intermediate connector to allow an Ipod to be connected to your older stereo/CD unit.

Crutchfield Customer Review (What's this?)

I'm rocking now. The other reviewer forgot a critical step. You have to
manually turn your AUX input "ON". These head units are not computers
that automatically sense a signal. Anyway, it works great. I am very
pleased. I am just a little upset about the cost of the cable. But,
crutchfield made up for it by their super fast and good service!

Crutchfield Customer Review (What's this?)

I unplugged my CD changer and plugged this in hoping to use it to play from my MP3 device. The
Alpine stereo didn't recognize that anything was there and wouldn't let me select the source.
Don't waste your time and money on this product.

Hands-on research

What's in the box?

Download owner's manual

  • 11" Auxiliary input adapter cable (has an 8-pin male M-Bus connector on one end and left and right female RCA connectors on the other end)

Product Research


Auxiliary Input Adapter Application: The adapter converts the Alpine M-Bus CD changer port on many Alpine CD Changer controller receivers to an auxiliary input. The Alpine head unit must be Versatile Link (KCA-410C) compatible. This allows you to input line-level audio signals from such items as portable CD, MiniDisc or MP3 players, VCRs, satellite radio receivers, or video games.

Note: If you use this adapter as an auxiliary input adapter, you cannot connect an Alpine CD changer also.

Connectors: The adapter has a right-angle M-Bus connector on one end and gold-plated left and right RCA jacks on the other.
