hey guys, i need some help. I have a nice 10 farad capacitor to my subs. But the problem is that the lights still dim to the point that my sidemarkers dim, license plate light and even the LED's(very slightly, you have to stare at them) what am i doing wrong???

 

Hmmm Let me take a look at the next meet.

 

Upgrade your big 3 and maybe your alternator.

Your sig say you have 2 12s and a 10 farad cap but what size amp is pushing the 12s?

 

Are you sure the cap is connected properly?

 

Yeah the cap is connected correctly! I hope ? I had it installed. The amp is a 2 channel 250 watt rms. I'm going to the meet on Thursday! Ill let you look at it Mike If you're going down to Autobacs!

 

Sometimes caps don't help much at all, especially if they are cheap ones. Also, caps can/do go bad, again especially if it is cheap or not properly charged when it is installed. I've owned some that seem to completely cure the problem, then I've had others that seem to do nothing at all. The right way to fix the problem is to get a better battery and a bigger alternator. If the amp, lights, heater, AC, etc is drawing more current than the alternator can produce then it won't matter how big the cap is, it just won't fix the problem.

 

You're running 2 kicker 12's with a 250 watt amp? I's guess that they are wired to the amp with a very low impedance to the amp. Take it back to the shop and let them fix it.

 

well i looked at the amp and it actually says 1000 peak watts! I don't know!

 

LOL 10 Farads

 

That is my current setup, i have no capacitor and i get no dimming even on 30 volume on stock head unit... i do get door lights to dim if i have them open....

when i had 2 12 l7 kickers in my other car i had a 1600rms watt amp pushing them i had dimming till i got a i think 1.5 farad cheap cap, and i had no more dimming issues.

so from that alone id say take it back and have them fix it since there shouldn't be any dimming at all with a little 250rms watt amp pushing a sub or regular speakers.

 

ugh! im gonna take a look at it all!
