I am working on a Bose car amp model:
4A5 035-225 143604 /4306Year:March 1991
came out of a 1993 Audi Quattro 100CS 2.8 and I need a generic part for:
U1=Bose # 131354=op amp IC=20 pin dip U2=Bose # 134499=Class D amp IC=20 pin dip
note:many car makers use these factory Bose car amps in their upper class models.Thanks for replies

1993 sounds a little old to use a switching type PCM output. Are you sure? Sounds like junk yard time. Good luck getting Bose factory parts.
