Hey all,

I've noticed my headlights dimming when the sub hits. I was reading and people suggest doing the big 3 over the capacitor/new battery/new alternator.

I'm just curious as to what I need to do this. I read but all I got was bigger wire.

What I've gathered is it's bigger wire to the alternator from the battery, grounding the battery to the chassis and bigger wire to the amp?

 

The Big three mainly consist of running bigger wires from anything that is connected to the battery.
Here is a great example of another member doing the same to his truck.

I was looking at that post earlier. I'm not sure how, but I missed the first paragraph telling us what he used lol.

Thanks.

 

The third thing is actually going to be your ground from the engine (alternator) to the body. but yeah, alex linked my thread above showing my install.

 

Well, once I get everything I need, if I run in to any problems, I'll shoot you a pm.

Thanks guys.

 

I was reading that post and I basically did the big 3 to. My truck but only on the second battery not the starting battery.... Ive always read the big 3 being 1. Battery. 2. The alternator 3. Wire

Well that's cool to see

The build your doing is going to be easy . It was for me
