’92 Sable w/ Premium Audio Preamp

I have tried to install a Blaupunkt CD Receiver in my son's car but there is nosound.  Crutchfield is no help.  Took three phone calls to convincethem that this car preamped speakers and then when five wire workaround did not work, sent me a PAC adapter and this does not work.

Five wire work around got sound when I disconnected the speaker terminaland then reconnected but lost sound when changing channel or turningunit on/off.  Needless to say can not plug/unplug terminal while driving.

Lost confidence in Crutchfield.

Anyone have actual replacement/successful experience with this Ford setup?  This can not be a big deal.

What is the way to get sound? Car speakers are fine. Only problemis aftermarket receiver will not give sound (25 watt Blaupunkt;  PAC OEM-2 System Interface not a solution.)

did you hook up the amp remote wire from the blau to the power ant/remote circuit on the interface harness you used? sounds like you are not remoting on the factory amp, you may also want to look at an amp elimination kit as opposed to amp integration.....

The PAC is wired according to specification.  Everything goes to andthrough the PAC.

The thing that gets me is that absent the PAC - when I disconnecttne speaker harness and reconnect the harness THEN I get sound  - perfectsound (the five wire workaround - common negative and the four speakerpositives to the preamp) until I change channels or turn unit on/off.

Then I have to disconnect/reconnect/get sound.

Why do I get sound upon reconnecting the harness?  Then sound goes awaychanging stations?

I am about to give this over to an installer. 

Crutchfield used to be reliable.

Metra makes an amp bypass harness that is super easy to use.... sounds like you may be oversaturating the input stage of the factory amp... are you running line level into it or preamp? Metra makes a preamp integration harness for this vehicle for cases just like this... works great if your HU has dual pre-outs.....

Thanks for the tips.

But I am not going to rewire speakers, nor tamper with the OEM installationin case I sell the car it will be OEM, including the radio.

There is a work around this and it my be this Metra harness.

I do not know what a HU is, but the PAC adapter does have dual pre outs,so I will look into this option.

Otherwise, I'm caving and taking to installer.

The Blaupunkt is nice and I am sure my son will enjoy it.

It has all the latest features and it fires up fantastic when

I can trick the speakers to sound.

i dont know what BTW means.... kidding.....

the Metra amp bypass is super easy to use... you unplug both plugs on the amp and plug them into the bypass harness, then all your connections are made at the radio plug

OK guys, I figured it out.

I have been installing radios in cars since they were 8 Tracks.

Just not Fords (I don't like Fords) with this preamp set up.

The trick is to wire all the speaker negatives all to (here the WHITE/ black wire)

the common negative to the preamp.  This is on the output side of the

aftermarket receiver going into the Ford preamp.

The preamp input is five wires- one common negative with the four

positives for the corner speakers.  Works like a charm.  I just had to think of it a

little bit. 

It was Crutchfield that told me to tape off the three remaining speaker

negatives.  That was wrong. This left the speakers essentially out of

the circuit.  I was pressed for time and I tried to take a shortcut by consulting

the Crutchfield "experts".  When I ordered the Blaupunkt I talked to an

expert who assured me that "Premium Audio" on the speakers did not mean

a thing.  Wrong.  Three phone calls later, Crutchifield conceded a preamp

setup.  I'm a law student and my professors do not leave me time to do the

things that I really enjoy - which could include tearing up carpet and body

panels to install upgrades.

 I probably did not need the damn PAC adapter but I am not rewiring anything

again to take it out - no time.

 As the system is configured right now I can pop the OEM radio back in when I

go to sell the vehicle.

So remember, "Premium Audio" on a Ford of this vintage means

PREAMP.

Still have not lost the touch after all these years.

The Blaupunkt fires up great and I have adjusted the audio so that

the sound distorts just under maximum volume (~95%) output.  Otherwise

it is clean sound.  Sure it can be tweaked more but this is perfect

for a 16 year old who got his license three days ago.  If he wants to turn

the car into Carnegie Hall so be it.  Right now I am not worried he is going to

wreck while fiddling around with a portable CD player rigged up through

a cassette adapter device.  Now he just sticks in his CDs, burns or otherwise,

and enjoys the ride. 

Thank you all for your 2 cents worth.

The problem has been resolved.
