Power issue...What's Missing?

[Skizza 10+ year member]

in my 2005 Dodge Magnum, my headlights don't dim at all, but my dash cluster does...I have:

• OEM Battery
  
• 3 Kinetik KHC 700 Batteries
  
• Ohio Generator H/O 320amp Alternator
  
• Big 3 Upgrade
  

Running:

• CT Sounds 125.4 amp
  
• CT Sounds 1400.1 amp
  

Pushing:

• 2 Hertz HCX690 6x9's
  
• 2 Hertz HSK165 6.5's
  
• Two 12" PSI Stage II Custom Subs
  

I've had s**tty systems in the past where interior, dash, and headlights dimmed, but tried to do everything right this time. Never seen JUST dash lights dim andI thought I had enough power to keep that from happening, but apparently not. Do I need to swap my OEM bat with a different one? Using o Gauge wiring.

I would swap the oem battery anyway. but for the problem you might just have to upgrade the ground for the dash components. sometimes factory grounds are just insufficient to begin with and then put the work of the amps into the equation and they really suffer.

Cool, thanks for the advice!
