I have a 96 i30 and I am thinking of upgrading the stock bose to the Pioneer FH-P4000. I generally want to change the factory just because it doesn't look all that appealing. Can anyone tell me if this Pioneer has comparable sound quality to the Bose, and if I do change it will I need to replace the factory speakers? Thanks

 

You should try searching since this has been brought up many a times. Anyway, no you do not need to change all the factory speakers, just get an adapter for the bose sound system. It'll run you about $50 from crutchfield.
