First off wasnt sure whether to post this in ICE or Electrical.... its electrical but related to adding ICE often so please feel free to move if it should be elsewhere!!
I have a standard setup currently - well a new headunit but thats it and I do notice that my headlights dim as I pull away from a cold start.
I am thinking ahead as I have a sub going in shortly and have read a lot on these forums that people experience headlight flashing after installing a sub on heavy notes - since I have already noticed this I must consider this carefully.
Replacing the "big 3" cables from alt to batt etc seems to be the first port of call.
Could anyone explain in lamans terms (preferably with piccies) exactly what I need and how to do this?
As I say I have read a lot about it in loads of posts about dipping lights and ICE installs here on the forum but most posts just say to replace these and I am not sure with what or how to actually do it - do you leave the existing cables as well for example?
