Hi Everyone,

I installed a new Alpine head unit in my '04 Frontier.  I had the stock Rockford Fosgate system and I bypassed the stock amp with the new head unit.  Everything works great but I get a fluttering sound from a relay near the fusebox when I am in the Accessory position on the key.  It is the same sound that you get when you don't have good battery contact but I double checked the connections and they are tight.  Any other thoughts?  I pulled the fuse for the amp under the hood, since this is not needed now.  I have not driven the truck yet so see if it happens then but I wanted to know if anyone has had this happen.  Thanks.
