Should I be worried or not? Headlights dim when head unit set close to max volume...
Here's my setup:
'94 Honda Accord
Kenwood Amp: KAC-X542
Kenwood DVD Reciever: XXV-05V
Kenwood Powered Subwoofer: KSC-SW1
SPL CP15 15 Farad Capacitor
Kicker CK44 - Kicker 4 Gauge 4 Channel Amplifier Kit
Yellow Top Optima Battery
It's been several months since I had the system installed and yes, it was silly of me for using such a large capacitor but got it new...cheap. Anyways, as far as i can tell, I never noticed the lights dim until recently. It's not very noticiable unless you have the volume close to or at max and actually shinning the light on something to notice the small dimming of the headlights when the bass kicks in. If you are just staring right at it, you wouldn't notice it dim. Should I be worried since I hardly drive at night and usually don't play the stero at max?
Oh, would this be a problem? Instead of hooking the powered subwoofer to the battery, I have it hooked up to the main relay in the engine bay (before the main fuse box). I don't think the powered subwoofer is the problem but can't hurt to tell all how the installation was done. Any who, would it hurt to have the power souce hooked up to the capicitor instead or just have it connected to the battery?
Your inputs and comments are welcome.

A cap is NOT a power source for the amp. You want the powerered subwoofer wired directly to the battery with a fuse close to the battery. I dont know know how thick the wire is to your main relay. If the lights dim, that just means that the subwoofer is drawing more power than your alternator / battery can supply at the moment. When the light is on, and you are at idle...your alternator is producing the least power. So the power used to power the lights is diverted to the subwoofer for that small moment causing it to dim.
But if you are only experiencing this at near max levels...which you are rarely at, I wouldnt worry too much.

And yes, I know the the cap is not a power source but since it has the availabe juice, I figure it will suppliment the small power lost.
Thanks for your input man.

I was joking about the "impressing" bit... more so testing.
