Re: P38 Harman Kardon Nightmare
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.
