Maybe your amp is drawing too much current, try using the Optima battery. The cap is like a reservior of power for the amp. Your cap draws power from battery (not that much), and then it stores it in the cap. When the amp need alot of power to push the sub, it will drain it from the cap instead of the battery.

Yes, the blue tube is my capacitor. In my case it is a 1.0F capacitor. The rule of thumb for figuring out how large of a cap to buy is that you need 1.0F for every 1000W of total power that your system has. So, if your amp is less then 500W, get a 0.5F cap, 500-1000W, use 1.0F, 1000-1500, use a 1.5F, etc.

And yes, as described above, a capacitor will store power for you so that your amp doesn't draw such high spikes from your car's system all at once. Without one you may certainly experience dimming lights when you're really cranking it.
