Very nice man! I also have an 06 with 4 18s...

Have you had any luck trying to get a 2nd alternator in yours? I have an excessive amperage 250amp but I need more.

 

4 18s nice no luck for a 2nd alt don't now any one that makes a bracket for it. I was thinking about makeing me for my truck but really haven't had any time to plan it out. Do you got any pics of your system or a youtube acount?
