everything im using is in my signature. could u explain what you just said in lamen's terms please? and how do i check how much amp power my alternator has..go with the 180amp one. its only 20 amp less at full tilt but 50 more at idle. You will use the extra 50 at idle. thats why its $70 more.
What amp are you using? Also how big is your stock alt? If you do the big 3 in 1/0 and upgrade your underhood battery to a good deepcycle, depending on your amp you might be alright with just that.
