Hello I’m a new focus owner, I drive a 2014 Focus titanium. I had a bunch of car audio installed by reputable installer I’m running 1600 watts through 4 gauge power wire. I got 4 door speakers that keep cutting out. But all the factory speakers do not I brought my car back to the shop to get checked out they say there is nothing wrong with the install and my alternator isn’t charging my battery enough and it’s only putting out 60 amps. I talked to the dealership and they said the alternator is 150 amps stock. I got my charging system checked and there is nothing wrong with my alternator or battery does anyone else have this problem. I have also brought my car to other install company’s and they also say that they can’t find anything wrong with it..
