I thought i had the Rockford system but it does not say it anywhere on the dash. But its the 6 disk changer with the aux input it says 8 speaker system on the window sticker. Its an 08 SE Crew. Is that the standard sound system or is that the upgraded one? It sounds good so im not upset either way. I told the salesman i wanted the rockford and he said he had one and sold this one to me.
