Big 3

What do I need to do for the big 3? Do I need to upgrade alternator?

[The enD 467]

Upgrade your stock wire with thicker one(depends on the amperage(look for charts for that)).

Positive battery to positive alternator

Chassis to negative battery

Chassis to engine block

This helps when you install an aftermarket system and you draw way more current. The stock wire is not accommodated for that, so when you add a bigger alternator/battery you should upgrade your wires too.

And with the big 3 will it increase power to the amp and fix the light dim issue when subs hit?

[emh9009 199]

It can help, yes. Will it remove it completely? That depends on each car and the power you're demanding.

My alternator isn't putting out much. Its stock. I want to get an HO one. But was looking into the big 3.
