Check all wiring to make sure nothing has come loose. When you get done doing that, do it again. Never hurts to check more than once.

Look at the amp after you turn on the truck a see what lights are on on the the amp. Mostly your looking to see if the power light is on and/or if the protect light is on. Dont turn the vehicle off right a way keep watching the lights for a couple of minutes to see if they change.
