I came into repairing a rockford r600x5. There are two spots that blew bad enough to leave marks on the heatsink and blow part of the trace up. However, I do not know the values for the parts that blew. On the bOttom it is D14 and D15. I'm guessing that's d for diode. I can't get the schematic from rockford. I've found cracked solder joints on the preamp board connections.
Anyone can help me out on the diode values that went in these spots, please help.

Likely an MBRA160.
Scrape away all of the carbonized board, down to clean material, to ensure that it's not conductive.

Perry, it in fact is the mbra160 on d14 and 15. I was able to snag the schematics for it from fosgate.
I see the same rectifiers are burnt out on my r600x5 also and figure why not try replacing them and seeing if I can save myself from buying another amp. Do you have a link on the mbra160 rectifiers? I notice there are a couple different ones and it seems you have been successful in your fix and you could help me out properly. Any information that would guarantee me getting the correct part would be extremely appreciated....d14 and d15 are the same parts burnt up on my amp as well.
Thank you
I don’t know if you already checked them or not but it appears the 2.2 ohm resistors are also defective
