What is it,& do i need one.

 

LOL, I have no clue what you are talking about!

 

(1)HO Alternator,(2) battery, and (3) power capacitor.
Not likely unless you are planning to add more amps...maybe a cap.

Try adding a larger alternator to battery power wire and larger ground wires. At this point, its the most cost effective upgrades.

 

Thanks vin,my headlights dim out just a little when the bass hits.

 

do you have a cap? if you don't you can pick one up for like 50 bucks + and that should help

 

Its pretty normal for your dome lights to dim while your stereo is playing and your car is idling at a stop light. The only time when it becomes a problem is when you're driving around and your lights dim. When you are driving around the alternator being charged much quicker, as opposed to sitting at a stop light, that's why the slight variation in amps/volts will dim your lights.

I'm using a 200amp alternator and a 15 farad cap and my dome lights still dims while idling.
