I found some compatible 1998 Nissan/Infinity Maxima/J30 Bose amps for $7 ea in the junkyard. Additionally, I have successfully repaired a pair of the original amps by swapping capacitors from used amps I acquired. The newer Nissan ones were much easier to deal with and are still running 2 years later.

I kept the front /rear part numbers sorted out since the Nissan applications have very similar sized speakers front to rear.
