Electrical Problem

I have a 95 GT 5spd...

I have the 240 amp(Yes 240amp) PA Automotive alternator.
Did the Big 3 upgrade. With 4guage wire.
Optima Yellow Top battery.

CDT Audio 6 1/2 components in the front.
CDT 6x9 Components in the back.

Elemental Design
Model Name : NINe.2 Amplifier
RMS Power @ 12.5v : 2 x 100W @ 4 Ohm, 2 x 200W @ 2 Ohm

One for the front speakers and one for the rear.

0 Guage from the battery to my distribution block. split to 4 guage to the amps.

Amps are grounded to the hole right next to the gas funnel thing in the trunk(4 guage).

When I turn the music up to a certain poin(less than 50%) My battery voltage goes DOWN between the N and O in NORMAL...

Even if Im driving down the road the battery guage will be normal but once i turn up the radio to a certain point it will stay up but it will fluncuate and all the lights will start going crazy like a lightshow until I turn it down.

I dont know what it could be.


I did have headlight dimming before I did the battery even with he 3G and new alternator.. but that is gone since I put in the Optima.

The first image is what happens when I turn it up the volume about 19 out of 35...
Then the speakers sound like they are mudded and sounds faded.

The second is normal...

Also when I start the car first thing in the morning the car voltage is at the A mark.

Could that be the problem?? I cut that wire and ran the new 4 guage to the battery???
