Hi there. Back track all of the wiring from when the Amp was installed. Disconnect the Amp first to activate the windows and roll them up. Check to see where the wires were tapped into. The ground wire should have its own wire to the ground. The wires may have been tied into the main circuits to the doors causing the power to overload. Electricity will go to the shortest path to ground, So if the Amp is the closest area then the power will go to the Amp. Check the fuse for the window switches and change them if they are burned. If you need further assistance with your windows down after installing an Amp, then seek out a professional, such as one from Your Mechanic, to help you.
