Perry,my son decided to help me out and clean the house,doing so he threw out the diagram of the parts removed.The only thing I cant recall is U04,D14,D12,Uo3,D13,D15.Would you happen to know which components went in these locations.

If U03 and U04 are the regulators, the L7812 and L7912 are likely good subs. The center leg of the L7812 will be directly connected to the secondary center tap or the negative speaker terminal.

For the rectifiers, the FEP16DT and FEP16DTA are probably good subs. The FEP16DTA will go in the locations where the diode symbols on the board are facing away from each other.

If you're lucky, the engineer from Kicker will see this and respond. He'll be able to provide the exact part numbers.

I misread the message. I thought he threw out the parts.

The following datasheet shoes the symbols for the diodes. Match the symbols to the part numbers.
YG225C2 pdf, YG225C2 description, YG225C2 datasheets, YG225C2 view ::: ALLDATASHEET :::

The center leg of the kia7812 will go to the secondary ground. The 7912 goes on the other side of the amp.
