Problem Solution
Protection/Red LED lights
up
Turn down volume on your head unit to prevent overdriving.
Reset the subwoofer by turning it off and on again. If the protection still
lights up, the subwoofer is faulty and needs servicing.
No sound Check that audio input connection is correctly and securely made.
If using low-level input connection, check the RCA cables are correctly and
securely plugged.
If using high-level input connection, check connection with the speaker wires
of your head unit.
Low output Adjust the remote subwoofer level control to increase sound level.
Input gain level is too low. Reset the input level control.
Check the frequency pass lter settings.
Hissing sound Disconnect audio inputs (e.g. RCA cables) from the subwoofer and power
on the subwoofer to nd out the faulty/noisy component.
Try to set the head unit volume as high as possible (without distortion) and
set the input gain level of the subwoofer as low as possible.
Squealing noise Check for improperly grounded RCA interconnects.
Distorted sound Check that the input gain control is set to match the output level of your
head unit. Always try to set the input gain level as low as possible.
Check that the frequency pass lter is set correctly.
Check for short circuits on the speaker wires.
Engine noise (static type) This is usually caused by poor quality RCA cables, which can pick up
radiated noise. Use only the high quality RCA cables and route them away
from the power cables, large wire loops and electric fan.
Engine noise (alternator
whine)
Check the black ground wire of the unit is properly connected to the metal
frame of the vehicle when using high-level input connection.
Check that your head unit is properly grounded.
Check that the negative speaker wires are not touching the vehicle chassis.
Check that the RCA grounds are not shorted to the vehicle chassis.
Subwoofer gets very hot Check the minimum speaker impedance for the subwoofer is correct.
Check that there is good air circulation around the subwofoer. In some
applications, it may be necessary to add an external cooling fan.
Auto power on not working Check that high-level input connection is made
Check that remote wire connection is not made.
Check that auto power on feature is activated by pressing the Auto Turn-On
switch on the subwoofer.
