What type/size capacitor should I get for my car audio system?

I have a Pioneer 800 watt amp pushing 2 12" subs.
The headlights on my car have started to dim significantly!
In addition, I have 4-gauge wires ran and a newer battery.
 
It's probably not a lack of a cap that's causing your lights to dim. Are they dim only when your bass thumps, then if you turn off the subs they return to normal? Take the car to autozone/wherever for a free alternator and battery test. If everything is ok THEN think about a capacitor.
Wal-mart has a cheap cap, 0.5 farad, which will be plenty for an 800 watt system. It's what I run on my 1500 watt without any problems
 
I recommend 1 farad per 500 watts, for optimal output. A 1.5 would be about perfect for you, just make sure it's functional. If it's not helping your headlights, it's not working well.
