Very poor radio reception

So I managed to fit my new stereo successfully (see this thread), and it's all good, apart from the radio reception. I previously had terrible reception, and it has not improved (can only get one really strong local station, and even then not always).
I have an in-windscreen antenna, with the Fuba (?) power amplifier, which I wired up correctly. I can tell it's not working because radio reception is vastly improved simply by holding my hand near the radio, or under the dash.
So, I know the antenna power amp is under the dash, but where is it exactly, and what does it look like? Can it be easily replaced, etc.?
 
Its a box about 4" square and mounted on the side of your car, on the drivers side under the dash. (I assume it's there anyhow, as I have a LHD, but the location of the ariel going into the screen is the same).

For me, first I'd confirm it's the right power source from radio to the antenna. The black wire bundled/attached with the main ariel lead is the one you need. Separate the connection you have already made to this wire (assuming you have), and bridge across the 12v switched source to the black wire. Any improvement, and you have a problem with the power source wire you've chosen from the radio. (although it doesn't sound like that from your "hand waving" test, check it anyhow. it's easy to do!)

If that doesn't help, check the connctor to the windscreen. There should be a small wire going from the box to the ariel. it is actually the ariel itself, but has a connector in the middle for if you break the windscreen or amp. follow the wire either from the box, or the screen, and you'll find it (be prepared to contort yourself into all sorts of positions crawling under the dash! [:mad:] )

If that's OK, the chances are it's the amp itself. You could probably replace it with a standard car ariel booster from anyone of these online stereo people, but don't quote me on that. I've never had to replace it.
 
Okay, cheers.

Yes, it's definitely connected right at the back of the stereo, because I checked the lead with a multimeter. I am assuming the wire is okay and it gets this 12V still when it reaches the amp.

I'll check the aerial connector!

Search also, there is a thread about 6-9 months ago with a paste-in of how to fix the connection to the screen.[FONT=verdana,geneva"] [FONT=verdana,geneva"]Mine doesn't work at all but my screen is broken so I'm waiting until I get a new one to worry about it. I have DAB so it isn't a hassle to wait.[FONT=verdana,geneva"]

Ha-ha! Problem solved! That article from 911 & Porsche World in the other thread helped, I worked out that I had not connected the proper aerial -- the one I connected was some wire that disappeared into the A-frame, presumably from some previous install or something.
Connected the in-screen aerial and Fuba pre-amp, and now I can get all sorts of crappy local commercial stations!
