Im in a bit of a DIY hole.
I got over exited when my new caps came in the mail and
forgot to take a picture of the back of the PCB.
Now I cant remember how the 4 caps were jumpered.
I have attached some pictures showing a
red or yellow option.

Can someone assist and determine which way I should
jumper the caps on the back of the pcb? (picture2; Red or Yellow)

Thank you,

You SHOULD be able to find a schematic somewhere.

Now, if the problem was with Bose, you'd be cooked.

Thank you for replying.
I was able to find my patent schematics that match the amp plate.
Unfortunately, I cant seems to match where on the board I am trying to connect.
I tried to zero in on the (470 uf, 2-25v, 2-16v) caps in question by trying to match z1,z2 d11, d12, r100, r101 components that seemed related and connected.

I also did a Google image search for Sunfire True Subwoofer. I looked at all of them and the home site but nothing helped.

Thank you,
