P38 Harman Kardon Nightmare

I've the standard head unit with the Harman Kardan speaker syystem. I want
to change the head unit but complicated with the amps inside the doors for
the speakers.
So does anybody know if there is an interface for a new head unit. It will
obviously have to be a pre amp output of the head unit. Does antbody know
the standard head unit output Volts for the amps.
The standard head unit is crap and want to put in a alpine or Blaupunkt head
unit.

What exactly is wrong with it?
Does it sound bad?
DA conversion is done at the CD changer, so changing the head unit won't
help the sound if you plan on keeping it and using the amps in the doors.
Good luck on getting another head unit to work with the steering wheel
controls, BTW...

The head unit and door/base amplifiers are designed to work together as
a unit, and as such it's not possible to use the amplifiers with any
other type of head unit. I've tried! I "lost" my head unit and tried
many specialists who said they could make an adaptor, and failed. The
best result I got was a continual gentle buzzing through all speakers,
the worst was severe hum. The only cure was a replacement genuine head
unit. Why do you want to change it? It works and sounds excellent.
You won't get a better sounding sound system without removing all the
speakers, amps and associated cabling. The steering wheel controls
won't work anything else either. If you've not got a CD changer in the
boot, that's relatively easy to add though.

I'm guessing you have the later simpler HK system without the door
amplifiers then. It's easy to drive the rear base amp/speaker and all
the other door speakers on this system as virtually any head should
work fine. Also, the original head unit wasn't the same quality as the
previous system, so changing it will improve the sound quality,
especially if you require MP3 playback etc. Though there's still no
way to couple the steering wheel controls to anything else mind.
