Looking to see if anyone has done the "Big 3" upgrade for their system? if you have or know how to do it....can you post with instructions....or "how to's"? if you have pics that would be helpful too

I've thought about doing it but never got to it. It serves an excellent purpose and has noticable gain. Pictures anyone?

Will be beefing up the system here in about a month or so and that will be one of the first things to be done, 0/1 AWG on all three and to the distro block. Will be a bit over kill as the systems RMS will be only about 1300 watts, but it will be fun none the less. Will see about getting pics up when I get it done, will be happening on a 99 altima se.

Just did this last week with 0/1 gauge.

1) alt to bat + is a pain if you don't want to remove coolant tubing,

2) if you pull the battery out, then the platform, then the bracing the grounds are very easy.

on side note, voltage output went from 12.8 to 14.8

I was reading more about this lately and apparently the Z's have horrible OEM grounding. I think I should be doing this sometime soon.

The connections should be explained in the instructions of the grounding kit, teddy.

is this an easier grounding kit or is this totally different???
