Aftermarket quest radio replacement

[mcdlnwright]

I want to replace my wife radio in her 2002 quest,
But the only issue is that we have a DVD player in it.
The radio now allow her to play a dvd on the back speakers or headphones,and we hear the radio on the front.
Is there a way for me to replace the radio with a new one that allows mp3's but still allows the splitting of the audio
