i own a 1990 - 200 turbo. it has the factory 6 speaker bose system that came in most models form this time... when i bought it the bose stereo cd player had been long gone and the previous owner said he could never get the sound right. i currently only get playback though certain speakers at erratic moments (which may just be a non grounded wire) and when the volume is turned up to a fairly loud level the playback becomes very very muddy and cracky... i have been told that bose speakers may possibly run on a different ohm setting, is this true? if so is there an adapter that will allow crytal clear playback through audi/bose speakers when being sent from a non bose deck unit? if anyone can direct me towards any leads it would be much much appreciated, thanks!
