Works well

Written By David, Minnesota on Friday, October 16, 2015

Crutchfield Customer Review (What's this?)

Easy plug and play, stations come in clear. Not much more to say about a simple product.

Pros: Fits well, has sufficient wire length to plug in with the stereo still out a little. (unlike some I've used in the past where you have to have it about an inch or two from its final position in the dash)

Cons: None

Did not fit my application

Crutchfield Customer Review (What's this?)

The adapter did not work with my cars antenna. I had to splice the factory end onto it.

Critical tip!

Written By Supertuner lll, North Dakota on Thursday, September 24, 2015

Crutchfield Customer Review (What's this?)

This antenna adapter is just what ya need for the 2006 Subaru Outback. Works well and came as part of the install kit offered. One critical tip tho: make certain you hook up the blue "powered antenna" wire to the blue one on your harness... Turns out the Soob has a 'powered antenna BOOSTER" that does not work if not connected. Hope this saves someone an afternoon.

Pros: Straight forward, works well.

Cons: Don't forget the blue wire on the harness...

It wasn't needed

Written By Robert, Oregon on Thursday, September 10, 2015

Crutchfield Customer Review (What's this?)

This was recommended by Crutchfield for use in a Sony stereo in my 2010 Subaru Forester. In reality, though the Forester connected to the new stereo without any need for an adapter. Crutchfield was AWESOME in crediting my money back without me even needing to ship it back to them. What a great company.

Works, but could be longer

Written By John S., Colorado on Wednesday, August 19, 2015

Crutchfield Customer Review (What's this?)

Works as expected, but could definitely be a couple-three inches longer, as it was the shortest of all the connections and made it tricky to connect and insert the stereo.

Antenna Connector

Written By Keith, Chicago, IL on Monday, July 06, 2015

Crutchfield Customer Review (What's this?)

As others have noted, could be a tad longer but does the job. Why Subaru has to come up with some different antenna connector is beyond me!

Pros: Works

Cons: A tad short

Listening to the radio is fun

Written By jackbattle, Georgia on Monday, April 13, 2015

Crutchfield Customer Review (What's this?)

Pretty soon you may not need to listen to the radio. In the meantime, you want an antenna that collects radio waves from the air and consolidates them inside your car stereo. Well this product does the trick, matched my car perfectly, and was easy to install. Lovin' this old-timey radio thing!

Pros: makes radio stations audible, easy to install, fits the car

Cons: None

Crutchfield Customer Review (What's this?)



Written By cdxskier, Columbia, MO on Wednesday, January 15, 2014

Crutchfield Customer Review (What's this?)

Used in my 2006 Subaru Legacy Wagon. Quick tip: do not cut the antenna wire from the factory head unit. Take some time to follow it (it's really buried) and disconnect at the harness.

While this adapter gets the job done, the connection the the factory antenna harness is pretty loose. I had to be very careful when reinserting the head unit back into the dash, as I was concerned the harness would accidentally disconnect.

Pros: Performs intended function

Cons: Really loose harness connection

Written By Hilldog, Union Dale, PA on Monday, October 21, 2013

No instructions came with this, so I cut the factory antenna cord, cut the adapter cord, and soldered them together.

Pros: works fine

Cons: no instructions

Does the Job

Written By achmafooma, South Riding, VA on Friday, May 24, 2013

Crutchfield Customer Review (What's this?)

Does the job and everything works fine with my install. I have two small complaints: first, the wire should be a bit longer. Subaru didn't leave much slack on the antenna cable in my 2008 Outback, so it was a bit of a stretch to get everything connected right. Had to position the stereo part-way in and squeeze my hand behind. Second, the connection to the OEM cable should be tighter. While fighting with the short length, it got pulled out a few times. But be patient and you'll get it. These are minor hassles and, in my opinion, only warrant a one-star deduction. If this stuff was too easy it wouldn't be as fun ;-).

Pros: Works fine, no problems.

Cons: Should be longer, and should snap more solidly into the OEM connection.

Something to Note

Written By Bass Lover, Tennessee on Wednesday, May 08, 2013

Crutchfield Customer Review (What's this?)

Five stars but......i needed an extension since my factory radio prevented me from locating my cd player in the normal location. My cd player is above the factory radio, about 8 inches further than the adaptor could reach.

Pros: Works as intended.

Cons: It's about five inches long.

too short for '08 Outback

Written By Anonymous, Boston, MA on Sunday, April 28, 2013

Crutchfield Customer Review (What's this?)

Functionally, this adapter is fine, and clips right into the Subaru harness, but for my '08 Outback, the cable was too short. It was stretched to the limit to get it to connect, to the point where I knocked it out twice trying to install the unit.


Written By A.Gray, Stonewood WV on Wednesday, March 27, 2013

Crutchfield Customer Review (What's this?)

I like the adapter only wish the cable was a bit longer.

Pros: good fit exact match.

Cons: Could be a bit longer

Subaru Antena Adapter

Written By Pete_VT, Northwest Vermont on Sunday, December 23, 2012

I did not use this adapter. I was able to use the stock adapter with my new head unit.

Pros: correctly converts Subaru connector to antenna input

Cons: not a 90 deg connector like the stock adapter

Subary Legacy 2005-2009 Antenna Adapter

Written By Anonymous, Gillette, NJ on Sunday, November 18, 2012

Crutchfield Customer Review (What's this?)

-Some directions would have been helpful explaining where the factory antenna plug is located and unfortunately that information was not contained in the Crutchfield Master Sheet. Though I'm sure if the direction were more clear I would not have assumed the antenna from the factory radio was hard wired to the car and I would not have spliced them together making an otherwise flawless installation take a sour turn.

Pros: -Right part.

Cons: -Directions were not clear.

I would prefer that the connector have a tighter fit, so that it would be harder to accidentally disconnect during installation.

Antenna connector

Written By DonA, Santa Cruz,CA on Thursday, July 05, 2012

Crutchfield Customer Review (What's this?)

Center lead wire not connected per ohm meter. Cut and spliced old OE connector to new lead. Not perfect install.

Pros: easy hookup

Cons: defective

Bad Cable

Written By Wiltonh, Mosier Oregon on Saturday, June 02, 2012

Crutchfield Customer Review (What's this?)

The cable did not work. It was open when using an ohm meter. The center conductor was broken inside the box end connector. The cable should be 2 or 3 inches longer to fit well in a 2006 Subaru Outback. There is a new on coming in the mail.

Cons: Did not work. Cable is a little to short.

Wasn't necessary (Don't buy?)

Written By Adam, Seattle, WA on Thursday, May 10, 2012

Crutchfield Customer Review (What's this?)

This adapter looks like it might come in handy for someone else. My base model 2012 forester already had the standard style plug for antennas, though, so I didn't need this. Rating it four stars because one-three seem harsh and I am not allowed to comment without rating.

Pros: Looks clean and sanitary Rarely barks No shedding

Cons: Wasn't necessary for installing JVC KDR730BT into a 2012 base model Forester.

Perfect fit

Needed this to install a Sirius FM direct antenna into the factory radio of a 2005 Subaru Legacy GT. Good fit. Pretty straightforward.

Pros: Straightforward, plug in, it works.

Cons: None

Does the job.

Would work but umm...

Written By Faith M, Wyo on Sunday, February 05, 2012

Crutchfield Customer Review (What's this?)

Give this four stars because while it would have worked great my 2012 Forester already had one on the factory unit. My advice is pop the trim panel off around the rafio and reach under the radio and on the lower driver side you can check it out.

Pros: Probably works great , plug looks like the factory style, also This one has a stright plug, factory one is a 90 degree plug

Cons: Subaru had one on the factory unit

Works as intended. I wish it was longer.

Written By Vlad, Boston, MA on Wednesday, April 13, 2011

Crutchfield Customer Review (What's this?)

This thing works as intended. Plugs snugly into the stereo unit, then the other
end to the car antenna plug. I wish it was a bit longer as the cable barely made
it. Subaru Outback 2005. Good call Crutchfield for including this along all that
is needed to complete the car stereo conversion job although not free as they
make you believe since the head unit is more expensive than the market price
from elsewhere, thus compensating for the cost of "free" accessories. Still,
it's nice not to have to worry what I forgot to buy to complete the job.


Written By Anonymous, Ohio on Thursday, February 10, 2011

Crutchfield Customer Review (What's this?)

It makes the connection from your factory antenna to your aftermarket stereo,
can't really ask it to do more. If you get bad reception, attach the antenna
wire (with be P. Cont) to the wiring harness, that is the antenna amplifier
which you will need.

Pretty Simple

Written By David, Austin, TX on Friday, August 22, 2008

Crutchfield Customer Review (What's this?)

Without this adapter you're not going to receive radio signals on your aftermarket head unit. It plugs right in, nothing to it.

Is there even another way to do it?

Written By riceye, Wisconsin on Monday, August 18, 2008

Crutchfield Customer Review (What's this?)

The Subaru antennae are different than most others. Without this adapter, I just don't see how an installation could be successful.

And the fact that Crutchfield includes this, and all related installation hardware for free makes it a no-brainer as far as whom to purchase from.

And fast, free shipping, too. WooHoo!!!

Just plug 'er in!

Crutchfield Customer Review (What's this?)

I have an 2008 Legacy, I don't know about other years but the 2008's have a powered antenna, without this connection, you get terrible signal. Other than that though, the product itself works great.

Gosh golly I love Crutchfield

Crutchfield Customer Review (What's this?)

Great product especially b/c I got it for free. It is a great adapter. No silliness and its real straight forward. Also it has a lot of cable so there is plenty of slack when you are attempting to move it around.
