RE: <90+> <FS>Bose System re-fit/Speakers for sale
I've found the same in earlier Audi "self-amplified" non-Bose systems. I
came up with a plausible alternative to rebuilding the entire system. I
bought a JVC FM-Modulated CD Changer. It plugs into the FM antenna socket
on any head unit, and sends the CD audio as an FM signal. You tune it on
the radio - very common. I've heard people criticize such setups because
the FM modulation "alters" the sound quality, but my system sounds
exceptionally clear and tight, without speaker or head unit change out. I
added a Collins self-amplified subwoofer (also installs without modifying
existing stereo hardware) and the system sound quality now surpasses my
$1,500+ aftermarket system that I'd installed in my previous car. Added
bonus - externally my stereo LOOKS stock - very low theft potential.
