Speedometer stuck all the way?

I just installed an amp in my 2002 Chevy Silverado, and I look at my speedometer and it’s stuck past 100. I take the positive terminal out, and put it back in and it went back to normal. What caused this, and how can i prevent it from happening again?

    Get the amp installed and wired properly.

    Check your amp wiring.  It could be touching/shorting a speed sensor wire.
