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.
