there is really not a big difference between the two hook ups. the aux input in the front is an easy plug and play feature where the rca is more of a permanent option. either way you go the sound should be the same.
I just have a quick question. In my car I have a deck that has both an aux input in the front and rca connectors in the back. And I was just wondering if there is any audible difference between the two.
