Default C6 amp/sub installed - start button issues

I just had a JL Audio 250/1 amp & Stealth Box professionally installed by a local audio shop. JL amp install kit used and have a Optima battery.
Now, when I push the start button to shut off engine, the motor is slow to shut down. As if the motor want to keep running until it stalls, not a quick normal shut down.

The amp/sub perform perfect, great sound. But, before I return it to the audio shop for troubleshooting, I just wanted to see if anyone had a similar problem or suggestions what to look for.

Wow, never run into that one so far... I would definately take it back to have it checked out... it sound like they tapped into some wiring and a small amount of voltage feedback is causing your problem. With the databus wiring integrated in the Vette audio, it is certainly not out of the question that this is what happened. Even 1/2 volt can cause your problems on a databus wire.

Hope this helps!!
