i .5 agree w/ loganberry. only upgrade your wire to 0 awg if your amp can handle it. 4 awg is fine for most people. if you started out running 8 and you didn't kill your truck then you're doing fine with 4 awg. big 3 upgrade is wiring over your factory battery ground, engine ground, and alternator power with 0 awg wiring. it's relly cheap and really helpful. i reccommend it for sure to anyone who wants to take stress off their electrical system. get a new battery, if headlights dim then do big 3 upgrade

big 3 question...my alternator power runs to the starter solenoid? not sure? if so jus but 0 guage on both ends of the power wire?

iRmARK88

you run on top of the wire which connects your positive terminal on your battery to your alternator

my positive cable goes from the starter solenoid to the pos. terminal

c&d technology batteries for the price are simply the best, there incredibly strong and incredibly affordable....i have 0 gauge for my sub amp (big 3 and 4 runs from front battery to back batteries) 4 gauge for my mids and highs amp, and 8 gauge for my sub wire

loganberry

the big three is super simple....

upgrade power wire from alternator
ground out the alternator bracket to the battery
then bracket to the frame...really easy
