The big 3
The Big 3 are the wires that power your system (that means all the electrical system, not only the sound system).
That means:
-The ground wire from your battery to the body of the car.
-The power wire from your alternator to your battery.
-For the third one, it's the one between your alternator and the body of the car(your alternator is grounded by it's frame on the engine, so you need to upgrade the ground wire between the engine and the body)
When you add a big sound system to your car, that means you will draw more current. When they build the car, the engineers didn't desing that system to provide that much current. So, if you want to get big power, you need big wires. Like some said in that topic, if you put a big power wire to power your amplifier, you also need a bigger ground wire from the battery to the car body. If you upgrade your alternator, you also need a bigger wire between it and the battery to be sure it can handle that bigger current. You can also do it with your stock alternator, it can't be bad, when you talk about wires, bigger is always better, cause the bigger wire, means less resistance, so better current flow. The only reason why oem wires are smaller is because bigger wires cost much money. So if cost isn't an issue, go with all bigger power and ground wires, but the most important ones are the ground wire from your battery to the car's body and the one between the engine(or even better, on one of the alternator's mounting bolts)and the body. The third one is the power one between the alternator and the battery, this is why we call it the BIG3
