250 amp fuse should be fine.. 1/0 wire

dont wanna fry shit... 400 is 2 much

this one? http://www.sonicelectronix.com/item32979Hifonics-HFi3000D.html

do you have HID headlights or regular?? i would try hid headlight low wattage used may solve your dimming problem


seems to em you have 2 option your running to much amp, what engine is in your charger

you have either 140 amps or 160 amps aqlt options, anything above 150 amps your going to dim your lights

big 3 wont help you may need to get 1 extra battery to even out the ripple or splurge for an alt that can supply what your amp needs

mechman or other high output alts, keep in mind are you goiing to be sitting and idleing or at max idel while driveing

both are differant internals for working to what you need, you sould look for an alt that is slightly above your amps useage

yea that amp is the one i have atm, and i ave reg headlights . i have the 5.7l hemi i believe its the 160 amp alt. i already have a 2nd battery along with my stock battery in the trunk.

so basically i dont NEED to buy a big 3 kit i can just buy some 0 guage wire and terminals and do it myself?

thats how i did it.. make sure u get a fuse for positive from alt to positive on battery

well some good news i think. so i checked out my battery in my trunk the actual car battery, i noticed that the power wire is already stock at 1 gauge welding cable( thanks dodge) soo i followed it from the battery in my trunk through my car under the seats and it connects to a terminal or bolt/bracket on the inside interior frie/wall dash , but the wire from the alt is like 4 gauge or smaller. once i find out where it comes out from from the engin*** im goin to replace that wire to the alt with a 0 gauge and then replace the stock 4 gauge wire from the actual battery with left over 0 gauge i have once i remove the 2nd car audio battery since it is years old and i dont think is actually making a difference. question is since that power wire is already 1 gauge it wouldnt hurt if i left it at that and just did 0 gauge from alt and 0 gauge from battery to chassis? i would need at least 10-15 ft of 0 gauge if not :/
