TROUBLE SHOOTING

No Power

If the LED on your dash remote is not on, check the POWER light on the chassis of MEGA BASS. If the POWER
light is on you will want to check to make sure that the cable connecting the remote to the chassis is not pinched or
disconnected. If th POWER light is off check to make sure that the power wire and remote turn on wires are connected or
a fuse has not blown.

No Restoration

When your system is playing and yet you don't hear any difference in the sound, try turning the knob clockwise. If
you still don't hear any affect, then you need to make sure that you have MEGA BASS in the right part of the signal chain.

Sound is Distorted

Should your system sound distorted or your speakers are moving way too much, you should decrease the amount
of bass restoration by turning the dash control knob counter-clockwise. You should also raise the DPF frequency or lower
the setting on you Bass Control.

Still No Good

Adjust the Bass controls by turning the sweep control clockwise to raise the center frequency. If you still have
distortion, you should power down MEGA BASS, and change the bass output settings inside the unit (See Page 7).
