Exact DCV measured directly across pins 4 and 5 of the output driver ICs?
The biggest problem might be an on/off click/pop.

So if my speakers are safe I’ll leave it just as it is, I know a high dc offset can kill speakers , but one on the limit … output driver is upc1270 ones?
That offset across 4 ohms is less than 0.004 watts. It's not going to harm a speaker. I doubt that it would damage the lowest power headphones.
Yes. I'd leave it as is because you may not be able to find replacement driver ICs if you make a mistake with these.

It does not move the membrane of the speaker at power on/off. It is silent. One thing that it’s not related , my DSP starts when it sense an dc offset rise from the player, and when I unlock the car or open a door it tried to start 3 Seconds and then it shut down, it does not start the amps, can I put a cap or something to filter that residual ?!It is wired from a channel , player speaker output to DSP high-level , just so I can trigger a remote.
Your DSP should have multiple ways to switch on. The DC is likely triggering because the head unit us being used to produce some sound when you arm'disarm the alarm or lock/unlock the doors.
Why does it matter what the DSP does if the amps are not switching on?

True, it have vox that sense an analog signal, the dc offset and the classic, but I don’t have rem out on player.
