I have had my '08 Sahara for about a year now and since I've had it, I've never had the horn go off when locking and remote starting. Just yesterday, after reading another post on here, I stuffed the sound bar and sub box with poly (sounds great) and this morning when I remote started it I heard the horn, seemed odd, but I didn't think anything of it. I get to work and lock it up and the horn goes off when it locks. I am wondering if I inadvertently re-enabled something the previous owner had disabled. Does this sound possible? Any insight on this would be appreciated.
