I was moving my ti elite xo from the trunk to my glove compartment. I plugged up the speaker inputs from the amp and I hear music playing through the xo. Is this normal?
Did you still have the speakers connected to the XO? If there was no load on it, it is possible. Especially if you had it turned up pretty loud. I have heard it before from speaker selectors. Most of the time when they are being overdriven.
