Bobby,
It's one of those things that built into almost all new cars and a lot of old ones (my 87'Corvette does it). It won't "ding" if you turn the key towards the start position but don't engauge the starter, but then all your gauges are lit up and working. I take it that you were talking about turning the key towards yourself into the accessory position to run the new sound system. I don't believe there's a easy way out of it unless you try and find the unit itself that's "dinging" and rip it out!
