Restoration Blog: 912/912E Audio System
 

Do you have an original working radio [i.e. a Blaupunkt AM/FM/LW], or is your audio system updated?  What's the best radio, antenna, CD, amp, speakers?  Can the components be installed in such a way your 912 still looks relatively original?  Where are some good places to locate the components?  Thanks to Jim White for suggesting this question.

From: Terry & Jean;  ; Our 68 targa came equiped with a Becker Grand Prix with an AM add-on. It does not work, am looking for someone to fix!

From: Steven Thomas;  ;  I am in need of information on radios and stereos for my 912....I have stock holes and cut-out in my dash....the ideal would be to find an original radio in pristine condition.....but then again I would like to also consider installing a new state of the art stereo, but I have noticed that they don't have knobs....the questions is can I purchase and mount one in my car without cutting further on my dash? If so then is there a recommended radio/stereo that really works well in this situation.   Steven Thomas, Santa Rosa, Ca.

From: Kirk Mcfate;  ; I have the original radio to my '67, it came in the bonnet when I purchased the car, however I don't intend to reinstall it.  The newer systems sound so much better.  Anyone interested in a 912 OEM radio?  Kirk

From: Patrick Van Asbroeck;  ; Hi, I got the article about the Blaupunkt repair which appeared in Classic Cars (november 96). For those interested here's the address:
Autoradio Wagner, Hardenbergstrasse 69, D-51373 Leverkusen, Germany. Tel: +49-214-61421 Fax: +49-214-66050 I havn't used their service sofar but from the article it seems they are very good in what they are doing. Patrick  

From: John f Lacey; ; ' 69 Targa #596 still has one original Blaupunkt AM/FM, one original speaker with undeteriorated grill cover in the dash, one original antenna, and two original antenna keys.  I am thankful every day, regardless of reception.  Best to all for the holidays.  John L.

From: Patrick Van Asbroeck; ; Rick, My reimported '68 912 came equipped with an American digital radio which certainly looked too modern in the car. Luckily my dad- the never throws anything away type- still had his first bought radio in a box. A Blaupunkt with FM range and original amplifier in a separate chassis in good condition. I tested it on a workbench and found that somewhere a short circuit was present. Being an electronic engineer I investigated further and found the short circuit was caused by an electrolyte capacitor in the amplifier box. A common problem on old electronic equipment and often overlooked. Replacing the faulty component was no problem. Everything worked fine again. The radio was then fitted in the car with the amplifier box hidden under the passenger foot panel. The original piece of interconnecting cable was of the exact length as if was made to fit in a Porsche. The original dash speaker was still in place and the radio was connected to it. Unfortunately one of the previous owners fitted speakers in the door panels.. They don't look right but are left in place till I find replacement door panels or a way to cover the holes in a neat way.
The antenna was replaced with a standard one which gave a much stronger signal and so more radio stations to enjoy. Note that to fit the antenna  easily you need at least   3 cm (1.2 inch) of thread length.  The fender has a second piece of sheet metal under it where the antenna fits and this piece is about 5 mm (0.2 inch) away from the outer side. I found that most antennas havn't got enough thread length to cover this distance. So check before you buy. Second difficulty to fit an antenna is getting the antenna connector through the hole behind the door. With the door left half open and a piece of coathanger wire with a U bend at the end it can be done. I found another period Blaupunkt  radio at the local second hand shop for 2$/Euros! I havn't tested it yet but its in perfect looking condition. Keep looking around, they are not that rare.
Regards,
Patrick

From: markmaui;  ;  Aloha!! My '68 has the original am/fm Blaupunkt radio with the original, center of the dash speaker.  Just the way god and Dr. Porsche intended!!!!!!!!!  FM seems to come and go as it pleases, sometimes the only station that it catches isone that plays 60's oldies, go figure.....  Most of the time. the sounds of the motor, and exhaust note are music enough!!!

From: David Lovato;  ; Merry Christmas!   Mine's got a posh Pioneer (if there really IS such a thing) installed by the second owner.  'Supreme Audio' or some such thing.  My last one had a blank-plate (matt black crackle finish), so this is quite an improvement!!  I'm tempted by the ads in Excellence and Panorama for relatively cheap Blaupunkts (y'know Munich, Milan or somewhere).  I've got the dual cone door mounted rounds, and a rear parcel shelf mounted set of smaller speakers that's covered to match the car's upholstery-  sort of semi-humped mounting.  Altogether, I get decent reproduction, but could do with mounting a 4-way amp/booster.  I read in Classic Cars about this guys upgrade in his 356 that retained the original look (amp was hidden under the passenger floorboard if I remember correctly).  The conversion was done by some guys in Germany who refurbish OE radios and supply replacement units.  I wonder if Father Christmas will ever bring me a CD-player?!!  (Er...Santa, mate, what about the mechanical stuff first-  if you're listening?!!!!)  By the way, you can get your Becker Radio/Cassette less expensively by buying an old Mercedes like my '82 Turbo Diesel.  I'll bet that thing'd slide right into my Porsche!!!
As always, grateful to the Beckers,

From: Christophe;  ; I don't have any radio but just an horrible hole. I'd like to find something that the car should have when you don't have a radio installed. Perhaps, somebody knows if it exists ? Christophe.

From: Scott McLean;  ; Original Blaupunkt AM - good for listening to National Public Radio. Scott McLean, 1969 912

From: Gavin;  ; Just finished installing my new audio in my 68 912. Consists of:
1. Amp fixed onto bulkhead to the left of the wiper motor (opposite side to fuses)
2. One speaker in each door
3. Line to mini jack lead (from amp to glove box)
Basically I have a period radio (inactive) and this system enables me to bypass radio and use any external playback device (Minidisc CD etc) in glovebox so keeping all as original (well kind of) and not having a tealeaf magnet on view. The downside as ever is don't play your latest CD at night when it's
raining!  The combination of full beam, wiper motor and 60 watts of House music (all night long ;-)
will leave your battery as flat as some US roadkill. Keep the faith

From: Alexander v. Wachter;  ; There ist a Blaupunkt FM/AM Receiver installed, what looks very nice at that Place. Also there are big loudspeaker wholes in each panel of the car-doors. The system is working if I connect the wires but the potentiometer from the Receiver is broken so I have the choice of very loud or nothing. I do not care about the funktionality because my car has a cheap S****** exhaust (terrrible bad quality from ************ ********* - sorry) Weber carburators and so the mechanical noice from engine is stronger than any FM-stations here in Munich, Germany ;-)  This winter-time the 912 is stored and not in use because we have salt at the streets and so I use an 69 Opel Rekord CarAVan (Station wagon) without any stereo system too. Meet any classic car lovers around April 2000 in Florida (Sarasota). Alex.

From: Dean Klein;  ; > Do you have an original working radio [i.e. a Blaupunkt AM/FM/LW]? No...but I'd like to!  Updated.   Current technology.  Best is relative.  I wanted cassette and CD capability, so I got an in-dash Panasonic Super Tuner and a Panasonic CD changer.   The CD changer goes through the radio, so the changer can be moved from car to car.   I also matched a power amp to it all.  The radio fit in the dash with ease (some previous owner/w***** cut the dash).  The CD changer fit very nicely in the front fender area, in fact, no mounting was needed.  It fits snugly on it's own.   I used super-velcro just to make sure.  The amp is also held in place with super-velcro.  I used soft velcro straps to hold all the hiring in place. 
My system is tidy, easy to move, and stealth. The "head unit" is not one of the most expensive (no need to entice someone to cut the rear window or the top).  I also have a radar anti-theft system wired in; the warning light is adjacent to the radio.   When it's engaged, a blinking red light is lit.  I think it helps would-be thiefs think twice.  YMMV, Dean
