Hey people with subwoofers!, Does this happen to you too? Options

Its real simple. It means that you need a capacitor/condesator for your system. Its needed to keep the voltage at a straight level.

Because your subwoofer takes a lot of power first place to notice that is your headlights. If its dark and you will look at your dashboard light u will see the same.

It could also mean that your battery is worn out. Dont know if its a old or new battery? But give some more information about your ICE setup. What kind of amps, subwoofers etc etc.

cap really wont do too much, bigger alt. will be ur best bet.

When you get a new battery by one for a diesel car. They have a higher cold crank rating than petrol cars, it means they can provide you with the power better than your standard one. the car will start better to as it will turn over quicker and your lights should stop dimming

if you are going to buy an optima battery please go with a Red top. With the problems you have been describing the red top is the one you need. Just check hood clearence before you shut the hood.

I can't agree with that. The yellow top is made for sound systems. Check out optima's web page.
