capacitor problems

do you think if i added more grounds in the engine bay it would help?  like grounding the motor to the body or chassis, run new grounds from the battery to chassis, to the alternator, to the body?

i was thinking about buying a yellow top battery, but someone advised me to try regrounding everything first.

There is no way you need a capacitor.  If your lights are dimming with 800 watts (kenwood makes an 800 watt amplifier?) then you have alternator and/or battery issues.

Yeah... Here is my electrical power supply setup:

105 amp alternator(f**k alterstart and their ubey gheyness)

I have a volt autometer in my car for a nice idea of how the system is holding up. I haven't dropped under 12 volts and only hit 12 volts when the car is off or at idle. When running it holds 13.5-14.2 depending on its mood mostly. I am pushing something like 1300wRMS plus the beastly heater/ac system in the car likes to suck it up as well. The only problem I have is that rattling on the plastic, but that has nothing to do with power. :)

If you are dimming at that, look into a more powerful alternator or a replacement.

(BTW your alt is 80 amp, so an upgrade might not be a bad idea?)

are alternators easy to install?

would i need a specific model, or do all alternators fit in any car?

i got the car from my mom about 2 months ago cause she bought a new solara, so everything in it right now is 7 yrs. old.....1998.  i was also thinking, since the car came from daly city, ca....very foggy weather everyday, there can be some rust where all the ground points are right now, that's the reason i was asking bout if i regrounded everything if that would make a difference.

thanks for the info
