I got a 10x12 SEF comein for my Explorer II. I was wondering if i can just plug it in and go? I seen somewhere this guy put a 12 x 15 on his explorer II and said he had to do a factory reset to get the the coil to stable out. He said before he did the reset it was jumping all over the place and was very unstable. If i have to do this how do i go about it. Thanks Bill
