    Why is my JBL MR-145 Car Stereo System audio distorted?
    • K
      Kelly GutierrezJul 31, 2025
      There are several reasons why the audio from your JBL Car Stereo System might be distorted: * Check the loudspeaker wiring. * Ensure that you do not connect the front loudspeaker ground to the rear speaker ground, as this product contains a biamp. * The loudspeaker may be faulty. * Distortion at the highest volume levels may be normal, as the amplifier has reached its maximum power output. * The power and ground wires gauge might be too small; use a 10amp cable or more. * Reduce the bass effect or switch off the loudness mode. * The boat battery and/or charging circuit may be faulty.

      Interference on your JBL Car Stereo System radio could be due to poor atmospheric conditions; try again later in the day. It may also be caused by a broken or damaged antenna or lead.
