So apparently no one knows about this amp...

[migueldeluna 10+ year member]

it should be about perfect for a pair of 400w dvc 4's.
As far as what it actually does...

I wouldn't at all say it CAN'T do 900w rms.

A year or two ago someone benchtested a 268 (with 2x30A). It did 923 at 4 bridged.

Fuses don't tell the whole story. ATC fuses can pass a lot more than rated current for a few seconds before blowing. The way amp designers specify fuse size varies pretty widely.

Thanks

I know all too much about this amp.

This amp killed my father.
