still dimming after big3,alt,and bat.

[ajm 10+ year member]

I was wondering if anyone had some suggestions as to what to do next. I have 3 10" L7's ran off a pa a3000db and mtx tx6001 components ran off a mtx ta7402 amp. I have done the big 3 w/ the knu kolossus 1/0, put in a 200 amp alternator, and optima yellow top and still seem to have having some dimming problems. Nothing TOO major but it is fairly obvious.

Umm... checked grounds and all?

Some dude had a similar problem, but maybe a batt near the amps will stop that

Yup, they seem good the only part of the big three that im not sure if I did correctly was the "engine block to chassis". Here is why.

In the first pic it says "negative to chassis" when really in the picture provided the wire is going from the "negative to to the body" not to the chassis/frame. So for the part that says "engine block to chassis" I have the wire going from the block a ground under the hood which is on the body. On the other hand all is good with the grounds.
