  i fix new sound system,bong very lond,something happen,never notice until my friend call & tell me when he happen to saw me at opp side of road tat my headlight dance to the beat of the music ...he say not enough grounding so......issit the more point grounding the better?? cos my only got the engine/alternetor ground to chassie....
  
  so how many point is good enough to prevent dancing headlight?
  
  trying to save wid grounding only as i dun intend to get cap.

  You a VS, voltage stabiliser. As I know, grounding do little to improve the electrical power of your car, just help to drain away eddy current or whatever to reduce noise. VS will help stabilise voltage output to your device.
  
  Or have you already installed 1?

  ur direct current supplies is fluctuating. this may b caused by a failing alternator/ battery / high EMF interference rather than grounding. if poor grounding, the dim light will n should b consistent.

  den Z-Stab leh????????? i wish to install leh..............but actually wads the actual use for it and is it really effective?

  you can read abt it at www.z-stab.com
  
  but i like to emphasize that this problem is not gg away becos u lup some cables m a voltage stablizer.
  
  u hv to trace n stablisize the voltage thru rectifying the faulty parts 1st. den use cables n volt stab to improve.

  Couldn't it just be a under-power battery trying to run a very high-end ICE. I read about that these things happened when your car is heavily ICEd, not necessary a connection failure.

  i use a 75 amp battery. two 12"sub, 1 pair 6.5" component,1 pair 4" ,these are connected to 2 amps.
  
  the others spks is connect from headunit.

  so u off the amp got this fluctuating voltage problem? getting z-stab mebbe good since it has led indication to tell u whether voltage is low / ur alternator is not charging enuff.
