Hey fella's


I'm tryin to work how hard/easy it is to upgrade the cable from the alternator to give my stereo/headlights more juice.

I have upgraded the battery to an Optima and added another 5 earths to car still gettin flickering headlights so my next option is to get thicker cable for the alternator

does this cable go straight to the battery ? this is what I have been told but from what I can see it goes under the Fuse box some where.

Please DONT recommend me to get a Cap for my stereo because they are B.S

Car is 99 WRX GC8
