Rockford Fosgate Punch 60 IX DSM

Will 51ohm gate resistors work with Z44’s in this amp ?

 

[Perry Babin]

Yes

Remember the problem with the 10uF@16 SMD caps in the amps of this era.

This one doesn’t have the card in it .

But I should replace all the ones on the main board correct ?

Post a photo of the board and the PC#.

That's not a DSM. It's an IX. The DSM had the problem with leaky caps. I don't remember these having them but you should confirm that none are leaking.

This is what confused me as to if it was an IX or a DSM

 

[Perry Babin]

DSM amps have DSM inline. The DSM on the IX simply means that it's using surface mount parts.

Power supply is fixed .

Now the left channel has little to no output

 

[Perry Babin]

Install the crossover card to full range.

 

[caraudioguy2100]

If I switch it to full range or low pass the left channel works correctly but now the right channel sounds like a 2khz sine wave

 

[caraudioguy2100]

In high pass mode left channel doesn’t work

In low pass mode right channel sounds like a sine wave but left channel works correctly

In full range mode both channels work correctly

Bad solder connections and dirty contacts on the crossover board can cause strange problems.
