Mini Cooper 2003

I recently installed a aftermarket pioneer radio and a aftermarket alarm system and the other day j took my key out of the ignition and my car music came on by itself with the key in the ignition and I tried to start the car and it was just clicking like when a starter goes bad ,, that type of noise.. What can I do to get this fixed???

Have you tried checking the battery ? jumping ? might be a dead battery
