this is old 16 years so i am sorry if i am wrong this sound like the symphoni sound system   if that is what you have
you have to get the radio repair  the problem is that there is no parts for this radio anymore  also some of this vehicles came with a factory amplifier that is in the trunk  left side if you have one look there first
