Standard Troubleshooting Tips
-Check Amplifier First
- Ensure Ohm Load matches output of subwoofer
- Ensure no protection light is showing on the amplifier
- Check fuses to ensure no blown fuses
- Check Ground Wire connection
- Ensure wire gauge is large enough for power, check RCA cables.
- Check all wire connections to ensure no loose connections.
- If Sound is clipping
- Clipping sounds are generally due to an overtaxed amplifier. By not being able to provide enough power to the subwoofer.
- Burnt wires can also create a clipping sound, as well as a bad ground.
- If no sound is coming
- Try replacing the RCA cables
- Verify the head unit is turned on, and that output is working.
- Try a good speaker that isnt in your car, If still no sound then you may have a child mode setting on or faulty amp
- If Hissing or Distortion
- Test all speaker wires, or patch cables. Ensure they are not running along side any power/ground cables.
- Try higher quality cables with more shielding.
- Unplug speakers from the amp, if you are still hearing then you will need to check for a bad ground.
- This may also be a problem with a bad head unit.
- If Subwoofer sounds like air is escaping
- Ensure subwoofer is mounted properly
- Ensure that the ohm loads match
- Check all power ratings, the amplifier may be overpowering the subwoofer.
- If there is a rattle, check to ensure it is mounted properly and box is in good shape (no cracks or seal issues)
