Helps my amp respond faster, or i should say on time, no more dimming lights. :)

I have a 130 amp alternator, 2x 120ah batteries and 0 gauge all over and bought 2 of these 10 farad caps. Lights still dim slightly with the 400 amp drain of my car stereo. Voltages instantly drop down to 11.0v on hard hitting notes, in reality I dont think they make much of a difference, but they are shiney and look good.

It works right. The screw holes break very easily so don't go jammin screws into them as hard as you can.

Keeps my system running good, had a good clean install and it looks great.

Better than four sixty pound one thousand cranking amp batteries.

No problems with this yet and had it 6 months. works great lights don't dim anymore and sub sounds real good

I have over 20 plus years installing audio systems and I must say it is about time someone came out with a product that really makes a difference. I'm running over 2000 watts RMS at 1/2 ohms and not once has my lights dimmed or my car ever not want to start. I would say even on a small system you can't beat it for the money and quality.

This adds a great look to my setup has helped my lights from not diming as much but i don't think it really is a 10Ferit cap its maby 5 Ferit cap maby I havent tested it to see exactually how much it puts out but yeah works great never had a problem with it its a good deal for the amount you pay!

I bought this capacitor expecting very little since Boss and Planet Audio are not exactly well-rated brands, but sinc ei have installed the capacitor to my system, my lights don't dim and the voltmeter shows my 2000W amp is draining it, like its supposed to. Works well. For only $60, why spend $200 on a Fosgate??
