Looking to put a new audio system in my 4 runner. I'm trying to find some ideas of what to throw in there. I already have JL c2 400x in the front and i'm going to get the matching 5.25s in the back. I'm thinking i'm going to stick with JL for the sub too. I was planning on making a BFM auto tuba box for it. Anyone ever use an auto tuba on here? I'm really curious about what to get for the the head unit and amp. I want something that will be nice with good sound quality (i'd assume they all are different). I only need radio/cd/aux jack. Dvd would be kind cool if it was a touch screen. Anyone have any sweet car systems they want to show off?
