The Big three Upgrade

its basically upgrading the three cables to a bigger gage wire...
1st is alternator to battery
2nd is battery to chassis
last is cable connecting engine ground to chassis

It is supposed to help with the electrical draw from running amps and subs

thanks for all the info i'm still on the fence about doing it i purchased a optima yellow top battery but still have lght dimming issues i will let you know what i end up doing

Hey ken thanks again for the help I Have power directly to battery its usually at peak bass hits. As for the current amp rating i'm not sure i have one mone 1100w memphis amp powering two kicker L7's
