Im thinking about using the alpine headunit powerpak. It is a 4 channel 2ohm stable amp. What Im wondering is for right now I am only going to be running the 2 speakers in the fairing. Can I only run the first two speakers leads(front) and not the other two(rear)? Once again the component system I am running is 2ohms. Another question is I currently have a kicker dx125.2 although this amp is not hooked up nor does it have high level inputs. So I will need a line out converter correct. Also this amp is 8.3125x8.375 is this going to be too big to mount inside the fairing?
