    Hi all I just fitted a pioneer deh4500. Into my 1999 s3.
    I bought an adapter cable from halfords which says its for audi rear amplified. Ive installed it and im only getting sound out of the rear speakers, theres also a high pitch squeal when the volumes low.
    My s3 has the bose system installed.
    Any ideas?

    Thanks again.
