Troubleshooting

NO POWER

If the LED on the dash remote is off, check the POWER light on the chassis of 
the MB1.
If the POWER light is on, then check to make sure the cable connecting the 
remote to the MB1 is not pinched or disconnected. 
If the POWER light is off, then check to make sure the power and remote turn 
on wires are connected, or the fuse is not blown.

NO BASS RESTORATION

When the system is playing but there is no difference in the sound/bass, try 
turning the dash remote knob clockwise. If there is no change, then make sure 
that the MB1 is installed in the right part of the signal path.

SOUND IS DISTORTED

If the speakers are moving way too much and produce distorted sound, then 
decrease  the  amount  of  bass  restoration  by  turning  the  dash  remote  knob 
counter-clockwise.  Be  sure  to  adjust  the  DPF  frequency  (higher  or  lower) 
accordingly to the setting of your Bass Control.

STILL NO GOOD

Adjust the Bass Controls by turning the SWEEP control clockwise to raise the 
center frequency. If distortion remains, power down the MB1 and change the 
bass output settings inside the unit (see page 5).
