The TruAudio D16 is stable to 4Ω, if the amplifier goes below 4Ω’s there is a good chance
the zone will fail:

Impedance

To fix you will need to bring the impedance back up to 4Ω or greater
Note:
Most 8Ω speakers have TRUE impedance of slightly less than 8Ω which could sometimes
cause an issue.
If you are in Bridge mode and the speaker stopped working.
You need to check that the wiring is correctly connected to the phoenix connector and the speaker
has an 8Ω rating. Speakers with les than an 8Ω rating can NOT be bridged.
If your speakers are very loud and the IC-SUB-8 subwoofer is not:
You can turn the input gain on the speakers down and turn the input gain up for the subwoofer.
There is a delay of about 10 - 15 seconds to hear music from the time you hit play:

This happens because of amplifier standards we must be in compliance with. If you would like to
avoid the delay you can leave the amp in “ON” mode. (when the D16 is not playing music for about
20 minutes it will automatically go into low power mode)
