a cap is bandaid for the dimming light problem, not saing they dont work, but unles su have a total of 2,500+ watt system there is no need for one.

i see u already did the big 3 upgrades which is what i was going to suggest, if the lights still dim out or u get voltage drops when the bass hits u need a alt with more output.

what ppl fail to realise is a cap needs to be recharged after every bass hit, if the alt is not up to the job to begin with the cap does nothing

on alot of gm stuff ive done the serpintine alts have 2 diff pully sizes on cars that would dim the lights at idle we would put on the smaller pully to speed the alt up to fix the issue at idle, so that could be something u can look into on ur truck as well
