Okay, this is driving me nuts. I got a Amp for a PA Speaker. The amps operating voltage is between 9v and 14.4v

My alternator is charging usually at 14.7v

Where the hell is a constant 12v? Or what can I do to achieve this? Or at least lower the voltage by a VOLT to get this thing to work when the vehicle is running and off. Because it works fine when the car is off. Checked my cig lighter on the dash and it's at the same voltage as my alternator. I am losing my mind over this. Any tips?

It's a Pyle PFA200 65W Amp
