I recently installed a subwoofer and amplifier into my mk7 fiesta, but now the windscreen wipers and power windows aren't working. There doesn't seem to be any other problems and the fuses for these look okay


(also there's a beep when you turn the car off in the engine bay which I haven't heard before) 


Thanks in advance,

sounds like you have wired something incorrectly, or you have created a short out?
