headlights dont dim

I don't have any other products to compare it to yet.

This may be the reason that my amp cuts out at extreme volume output, others are that I may need a better ground, an additional sub crossover, or I may have a defective sub or amp. Overall I think this product is good. I think if I do another install I will upgrade to the next size up from this company and go ahead and throw the extra battery in the trunk.

I seriously doubt this thing can hold 20 farads, (20,000 watts) of juice. However, it is still pretty heavy duty for a car audio cap. People with superior amps and subs dont touch what my system does, and I think its the cap rather than the dynamat or brand selections. Most people dont use a cap, and since they are less than a hundred bucks this makes them idiots.

I may be an idiot for not doing a diode assisted installation charge, I'd reasearch the need If I were you. System still works well, I have a few kinks to get out, but I doubt the cap is one of them.

great product

Great product. Lights up cool, but the lights didn't dim at all. I was pushing 2 Kicker CVR's at 1 ohm on a DB Drive 1000.1 amp.

Boss CAP20

This is good stuff, but its not the best quality, I am living in Ukraine, and my father is electrician, and he says that this capacitor does not have 20 farad, only 2-3. but it very good looking in my car.
