    Can't find these IC!

    I planned on reworking the amplifiers for my '96 Voyagers speaker setup, but I can't find information on the IC's. The main one is an NEC 9547A and is a 12-pin SIP or whatever. The other is an unbranded BH715H1 (an 8-pin SIP) which leads to the rear speakers, I believe and is used for low low frequency production.

    Anybody, have any rare datasheets? lol!

      Are there 2 rows of numbers on the chips? The 9547A sounds like 1995, 47th week, which would make sense in a 1996 vehicle.
