I pick up in some post to use the speaker protection with the realy not in series with the signal but shunt to ground so if I have some dc the realy swicth the output to to ground but this mean output short . Lm3875 datasheet speak of in chip short output protection , this mean I can use this idea with no problem?

The problem could be, in a protection project like the Velleman kt4700 with the soft start , all the time before the relays activation the output is shorted to ground
AFAIK, all the Velleman 4700 does is disconnect the speakers from the amp for a short while before the amp is fully powered up.
