Rockford Fosgate T600-4

The outputs were shorted in 1 channel .

I replaced the outputs and checked the source resistors gate resistors all check fine .

With the outputs in that channel it draws excessive current .

Are the A56,06 the drivers for the outputs on the main board or would the problem be on the driverboard for that channel most likely ?

If no one else jumps in here, post photos of the amp and driver boards.

Have you tried to get the diagram from Rockford?

 

[caraudioguy2100]

Here are some pics of the board .

I will call Rockford after posting and see if I can get a diagram .

Rockford won’t release the diagram since it’s still in production

Did you set the bias pot for that channel fully CCW after replacing the outputs?

 

[caraudioguy2100]

Yes

The PZTA06 and PZTA56 are the drivers.
