Condition





Some customers may comment on a rattle or vibration in the rear of the interior of the vehicle with the stereo at high volume.

Correction 1





Remove the rear speaker and apply a piece of foam to the rear retaining tab.

Correction 2





Install foam under the wiring. Refer to the arrows in the illustration above.

Correction 3





Install foam under the amplifier.
