Is My SFB3K Toast?

My current settings. Should I leave the high pass at 10 hz.? Remember, it's on 4- 8's. 3,500 watts @ 1 ohm.

I'd bump it up a bit. I think my subs recommend 25hz, but obviously yours may be different. That high pass is your subsonic filter.

Probably just my camera or the reflection from the sun.

Why do you have rca on the input and the output?

@MattinMO you can use them both as inputs, but you can also link to another amp with through the output rca.

Hmm I know on the Sfb line sundown put out a statement to not put a any output section unless it's going to another amp

This amp is an SIA3500, but my SFB ran fine like that for four months.
