Listening to Quran on car stereo speakers that are by the feet of the passengers

If the speakers are as you describe, under the feet and shoes of passengers, then tapes of Quran should not be played, because the fact that Quran is being heard from beneath people’s feet or shoes is undoubtedly a kind of disrespect towards the Quran. If a person really must listen to Quran, let him lift the speakers up so that they are not at the same level as people’s feet.
