I am getting no am reception and poor Fm reception. I am not getting power too the antenna amplifier. Where does the power to the antenna amp come from. All fuses are good? Any help would be appreciated.

Don't know your particular situation but is the blue wire from your radio connected? Oh, this is assuming you have an aftermarket HU. If you have a stock HU, then the power antenna + for a 2000-2004 is green and for a 2005-2008, it's yellow/black.

Thanks for the feedback....I should have been more specific. I have a 2005 outback with the antenna imprinted on the rear windon, not a power antenna. It is a stock radio.

There are two wires that connect to the antenna amplifier which is mounted to the hatch. One of the two wires is the antenna wire, the other wire is a power wire (black with orange) this wire should have 12 volts, but does not. I thought there might be a blown fuse , but all fuses are good.


Any idea where the power to antenna amplifier comes from? I am certain this is the problem , because I ran 12 volts directly from the battery to the amp and it works fine.

I had the same thing happen on my '05. The wires break inside the rubber boot that carries them into the rear hatch. I spliced extra length by soldering and insulating with shrink tubing. As I recall, the wire forin the antenna amp is in the left boot.

Bingo ....the hot wire was broken in the boot. Thanks for the help. Just solder a new wire and back to normal.

I have a 2003 Outback H6 and the radio didn't work when I got it so I replaced it. The antenna seems to be pretty weak, I can get FM stations OK if they are strong, but NO AM stations. The antenna is in the rear window, but I cannot find the antenna booster, if it has one. I am not sure about the pin on the multipin connector that might power the booster, but am not gonna take the whole radio out if I can't find the antenna booster. I have looked in the trunk and in the back. Do you think this is the problem? Anybody able to tell me exactly where the antenna booster should be?
Thanks

If you replaced the radio, you lost the connection that powers the antenna preamp. Without preamp power, the radio is quite deaf. Some FM will sneak through, but not as well as it should, and AM doesn't get through at all. The preamp power is a wire on the connector behind the radio. It'll be easier to solve on that end because you'll have sources of power readily available. There may not be a handy source in the rear of the car, where the preamp hides.
