roughly, about how much does the wiring, good alternator, and 2 batteries run $$$$$. Is it a lot. I know the alt will be a few hundred, but that is about it. I will probably have about 5K to spend initially, but I should have a few things done before this initial spending, like the alternator. Lastly, what is big difference between driver and SPL. I want tons of SPL, but will be driving and pounding it alot. How much of a difference does this make??
