The KCA-SR50 adapter lets you control a SIRIUS satellite radio with your Kenwood stereo. This adapter works with newer Kenwood stereos equipped with a CD changer connection, letting you control either of the following:

  • the SC-C1 SiriusConnect universal tuner;
  • a compatible SIRIUS portable radio, like the Sportster, Starmate, Stratus, or Stiletto, together with a SiriusConnect vehicle kit.

The KCA-SR50 adapter sends song text to the Kenwood stereo's display, and lets you browse SIRIUS channels by using your Kenwood stereo's controls. The KCA-SR50 adapter does not have a pass-through connection. You'll need to purchase an adapter if you want to connect multiple Kenwood components (CD changer, iPod adapter, etc.) to your in-dash receiver. Warranty: 1 year.

Note: A subscription to SIRIUS is also required. Satellite radio service is available only within the lower 48 states — not available in Hawaii or U.S. territories. Limited service is available in Alaska.

Great product, easy install. Compact and easy to tuck up under dash. More
than enough cable to run to unit.

Oh yes it does... and more!

Now when you pass people on the road with there Sirius mounted to the drivers left, up
on top of the dash... you'll say I remember those days. Now with my Sportster 5
mounted low, but all the controls going through my head unit, I'm as happy as one can
be! Tons of wire to mount anywhwere and not a large footprint to worry about. No lag in
response from selection to station move. It works as advertised... BIG TIME! Worth it!!!

Worked great with Kenwood KDC-BT645U

Had no issues connecting this up between my Sirius adapter and my Kenwood stereo. The connections are professional and sturdy, and it was up and running very quickly.

I find extremely difficult to believe that the functionality of this device can't be worked into a Sirius-ready receiver.

Works as it says

This box is needed for a Sirius direct connection to a compatible head unit.
This box takes the generic signal/connection of the universal Sirius box and
makes it compatible with the Kenwood brand head unit. It works.

I mounted it under my passenger seat (MX6) with [essentially] double stick

Great gear for the price

This product was exactly what I expected it to be. Extremely easy install that fits in the 2nd gen Tacoma Access cab perfectly under the rear seat. As always the customer support is awesome along with the price and product.

Works Like a charm

Crutchfield Customer Review (What's this?)

Install was super easy, must use with the SC-C1 tuner, works as advertised and I am loving Sirius radio. Bought from the outlet so it was 10 dollars cheaper. Had it up and running in little over an hour! Only complaint is clock on radio doesnt work dont know if thats because of the type of tuner I have or if its because of the sirius hardware.

Less is more

Written By Dean, South Central PA on Sunday, September 14, 2008

Crutchfield Customer Review (What's this?)

Less is more in most cases, and this is one of them. Last year I did a Sirius instal in my Jeep with a Kenwood brand module - it was one box. Oh so very easy. This year I go to do it and now I have to use TWO boxes - a Kenwood box AND a Sirius box. Shesh. K.I.S.S - keep it simple. If you can use one box to do the job, do it.

However, all that said, it was a straight forward easy install. Only thing that would help would be a longer cable. Not too much. Maybe 12 or 18 inches. I had just enough to go from the dash to under the rear seat in my bro's Grand Cherokee. I could imagine in a sedan or hatch if you wanted to rear-mount everything you'd need to get an extension cable for the control box.

Less is better!

This unit was exactly what I needed with my Kenwood Receiver. It allows you to rid yourself of that Sirius receiver; thus uncluttering your cockpit. There is one problem. I read that the cable was 10'; but it's only 8'. I wanted to put the unit along with the sirius adapter in the trunk; but needed that extra 2' that it was advertised with. This unit plus the sirius unit now allows me to use the head unit to control ever function. you can view sat info form kenwood head unit!

Kenwood is Sirius

Written By Travis, Orlando, Florida on Sunday, January 20, 2008

Crutchfield Customer Review (What's this?)

This adapter works well, and for the money you cant beat it. Kenwood hasn't let me down yet. You have to have the SC-C1 tuner for this to work. The best part is you don't need power. Your head unit supplies power to the tuner via a din cable and you plug the adapter into your head units CD-Changer control and your ready to go.

General Overview: The Kenwood KCA-SR50 Sirius Satellite Radio Interface lets you control your Sirius universal tuner or plug-and-play tuner (tuners sold separately) from your 2005-up Satellite Ready Kenwood head unit. In addition to the KCA-SR50 interface, you will need a Satellite Ready Kenwood headunit, a SiriusConnect Universal Vehicle Tuner (item number 607SCC1) or a Sirius plug-and-play device with a SiriusConnect Vehicle Kit (item number 607SCVDOC1) along with a subscription to SIRIUS Satellite Radio.

Compatibility: The KCA-SR50 is compatible with 2005-up Kenwood Satellite Radio Ready Head-units (which feature an 5L connector) and requires an optional SiriusConnect Universal Vehicle Tuner (item number 607SCC1) or SiriusConnect Vehicle Dock (item number 607SCVDOC1) and a Sirius portable plug-and-play tuner.
