I am looking to buy either the Kenwood DDX or The Pioneer Avh in dash dvd player , and I was curious if the the deck will make the system sound worse or better with the factory setup? I am quite pleased with the factory speakers and sound ,and don't want to change anything. I just want to make sure the quality doesn't go down by buying this new deck. Any input is appreciated.

 

usually it winds up sounding better.. more power,better eq etc..
