I am going to support kinetik on this one, but I am also going to say with current draw that large, you might REALLY want to look into a new alternator....guessing on the efficiency of the amplifiers, for 2600 watts your going to need somewhere in the ball park of 280-290 amps to run all of your electronics. Give DC Power a call and see what they have for ya
