What size capacitor do i need?

Question

i have 2 Kicker 07C12-4 150 w rms and 300 peak running off a Kicker 06ZX1000.1 500-1000 w rms

basically my lights dim and my cd player display says failure after runnin my system for about five min (with out the car turned full on, just running the battery) so i decided to get a cap to avoid any future problem, but i just need to know what size to get and if there is a difference in brands such as lanzar, RF, absolute, phoenix gold, etc. also what works well for other people, thanks in advance

Answer 1

1.  A cap will not stop lights from dimming.  You need to do a Big 3 upgrade, as well as a alternator upgrade, and a better battery would help.

2.  Ligts dim at 300watts?  I agree, your battery is a p.o.s.

3.  How do you have 300 rms / 600 peak, but running off an amp that is 1000watts rms?  Numbers are way off.

Get a smaller amp, get a better battery.  If lights still dim, upgrade your alternator.

Answer 2

How do you have your amp wired?  You should have the subs wired in series if you don't already (8 ohm load on amp).

If you have them wired like this and you are having headlight dimming issues then you have a serious problem somewhere.  It could be anything from a battery to an alternator to a bad connection.  

I would start by going to an autoparts store and having both your alternator and battery checked.  They should check it for free and tell you if they are good or not.  If they are good then you will need to look for a wiring problem.

Make sure your ground is secure and on bare metal.  Also, what gauge wire are you using?  Doing a big 3 upgrade can help but with such little power it is most likely something else.

You will not need a cap.  Don't waste your money on one because your problem will not be solved with a cap.  

Good Luck!!!

HOW is a CAPACITOR going to help your problem which is... YOU DON'T HAVE ENOUGH BATTERY?
