Voltage question

[Brent1223 10+ year member]

Is the voltage on my cap the voltage going to the amp?

My cap is usually at 14.2 (13 when the subs hit)... is that good?

Also, my radar detector (passport escort 8500) is always at 14.2 or 14.3, is that B/C the cap is keeping the rest pf my power at a normal rate?

Do mostly stock civic's run at this voltage? (2000 EX)

Just trying to figure out what's going on and all that.

THANKS!

Well, assuming the display is actually accurate; yes.

It's not good that it drops to 13 when your subs hit, if that's what you were asking //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Nope. The cap isn't going to keep the power to anything. The best it'll do is just offer quicker discharges of current to the amp when high-current is quickly demanded (quick, heavy bass hits). But it's voltage will rise and fall with the electrical systems voltage.

My guess is that the radar detectors voltage meter just isn't quick enough to respond to the quick voltage drop.

Couldn't tell ya.

So what does it mean if the cap volt goes to 13 when the subs hit? It's not backing up the car power? I thought it was and that's why the radar detector stays at the same volts?
