Thanks for the tip Gergo!
I disable the sound power management with the tlp.service and set the i2c-register with a own customboot.service after the tlp.service is started.
It works for now :o)

/root/bass-speaker-on.sh
#!/usr/bin/env bash
/usr/sbin/i2cset -y 3 0x48 0x2 0

/etc/systemd/system/customboot.service
[Unit]
Description=Custom Bootup Script
After=tlp.service
[Service]
ExecStart=/root/bass-speaker-on.sh
[Install]
WantedBy=default.target

/etc/tlp.conf
SOUND_POWER_SAVE_ON_AC=0
SOUND_POWER_SAVE_ON_BAT=0
SOUND_POWER_SAVE_CONTROLLER=N
