the ALB10 sound output blends with the rest of the
sound system.
The phase control compensates for delay between
the ALB10 output and the rest of the sound system.
Begin with the phase control set to 0 degrees. If
thesoundisadequatefromthenormallistening
positioninsidethevehicle,nofurtheradjustmentis
necessary. If the sound is thin or lacking bass, adjust
the phase control until the bass is full and punchy.

best possible match between the head unit audio
output and the amplifier input. Begin by turning
