I have a 4.0 farad power acoustic cap.

I am still recieving some light dimming on hard hits, and I have done the big 3.

Now on the positive side ( if I am correct ) I remember seeing a small adjustment screw phillips head.
Someone describe what this is for. Thanks

 

It adjusts the volt display. Use a good voltmeter and make the display read realistic.

Doesn't affect the caps capabilities (or usefullness) at all.

 

You'll always get dimming when using lots of power thats the way it is, the only way to eliminate it more after getting the big 3 and cap is with a bigger altenator. The Cap only "softens the blow" on the power system. You'll never get rid of the dimming 100%

 

Caps also filter out unwanted ac voltage from power line.

 

Why do you have AC power on your line?

 

HMMMMM

this is a male dominated web site
we obsess over capacitors, perhaps one of the least important parts of the overall system
capacitors in car audio have a long cylindrical shape
most feel bigger capacitors are better than small capacitors
chicks dig capacitors


I forget where this was going but it was gonna be good

 

If you can't live with dimming and you've got about $250-$300, get a new deep cycle battery...like a Optima Yellow Top or something similar....no phallic qualities....its square!

 

Alternators in your vehicle makes A/C voltage then convertors it into DC voltage. Sometimes depends on your alt, condition, etc A/C voltage will leak out.

 

should be ripple DC after a bridge
