Hey guys,

Does anyone have instructions/pictures for the big 3 upgrade on an 04 f150 supercrew. Also, how much 1/0 do I need and how many ring terminals?

Thanks,
Mike

it's a waste of time and money. Been running over 2k watts in my truck for the last 3 years and have never had a problems. The only upgrade I have is a yellow top, but when I do my next round of installs i'll be throwing a bat cap in there. You'll be fine. If you don't believe me go to diymobileaudio.com and do a search on big 3 upgrade. Most will tell you it's a waste of time.
