I called them actually not too long ago, I was going to buy a Xs power XP2000 battery along with my head unit I just bought Pioneer AVH-X3700BHS together tonight. But anyways, I called them to try and work out a deal and they weren't really wanting to deal. I told them I could buy both items from Sonic Electronix store ON ebay for $494.18 with free shipping. The lowest they were wanting to go via phone was $544.20. soooooo I just bought the head unit for now and will purchase the battery this coming up weekend.

Are all mechman alternators 12v? or when you order them do you have the option between 12-14-16v? I've never had to order one, so forgive me ahead of time, Thanks!
