Has anyone done a DIY big 3 on 3g TL? i have been searching, but couldn't find any.

 

x2 on this question, and "ezland00" quick question..do your interior or head lights dim when the bass hits from the jl sub and amp?

 

No, i'm doing it because my battery is dying and i am getting noise.

 

One guy did it a while back and posted about it, I mean like in 2007! His audio system preformed a whole lot better, and I remember that he used black wiring, I think 4 gauge for everything...

 

so big 3 means upgrade cable using 0 gauge wire from battery to alternator(+),battery to chassis (-), and chassis to engine block(-).

Here are my question for those who have done this before.

1. Where does the stock + wire from the alternator leads to? I only see + wire from battery going to the starter and fuse box.

2. where is the stock wire for the engine block to cahssis?

thanks
