Default 2008 Kicker zx2500 help

Iím new to this
Iíve read all the threads on the zx2500
Having trouble finding the part # for D702 and D703
They are the large diodes located by the B+ and Ground terminals
The insulation is missing on mine, and the pics of the zx2500 Iíve seen on these threads show a partial part # ďA 6Ē
As seen in the pic I borrowed

Also, looking for part # for the resistors on the output section labeled R316 and R310, between the mosfets labeled Q314 and Q313

It looks like there have been some previous ďrepairsĒ done behind the mosfets on the circuit board itself with a piece of wire
Maybe thatís causing the continuity Iím seeing between all the resistors and fets in that bank
The rest of the board seems fine


I hope Iím using the right terminology and that this is making sense to someone 😂

They are "INVERTED POLARITY" protection diodes.
If you accidentally invert the power cables, this diode blow your amp fuse to self-protect.
You can replace it with this https://www.tme.eu/it/Document/be2d9.../10a05_ser.pdf

Thanks for the quick reply!
So I’m assuming it’s a 10A6 then?
Or can I replace it with anyone of these rectifier diodes on this data sheet?

You can use diodes that have huge amperage and right voltage capability, so the diodes that i've posted are ok!
p.s. R316 = 100Kohm - R310 = 10ohm

Thank you very much
I’ll post how things turn out when the new parts come in
Gonna replace all the 3205’s, 9640’s and 640’s mosfets
Along with any 100kohm and 10ohm resistors showing continuity
And those two rectifier diodes by the power supply

Those are 1/4w resistors right ����*♂️?
