5ktq 10 Speaker Radio

[JJK1204@aol.com]

Hi all,
The radio/cassette in my wife's 87 5ktq has quit, the tape drive died. I have
a Blaupunkt Lexington cassette/CD controller from a former vehicle. I have
been told that the 10 speaker system uses amplified speakers, from looking at
the wiring diagram in the Bentley manual it appears that only the rear
speakers are amplified. I believe this since the amp is in the trunk. Can
anyone guide me through the installation of the Blaupunkt? Do I have to use
the isolator that I purchased when I first bought the car? If yes, how is it
wired into the circuit?

Thanks in advance,
John Katos
