Bought this cap a while back and it works perfectly. Whether or not it is actually capable of 8 farads who knows, but it is doing all the work I need it to. The blue backlighting is also a plus.

I bought it because my sound system would dim my lights BAD. Once I put this in I didn't charge it all the way so it wasn't really helping, but as soon as I figured out why it wasn't performing how it was supposed to I discharged and recharged and now it's working great. The blue illumination is awesome.

Looks great. Lights up blue - I like the color. You can hook up many small lines to it or a couple big ones with o-ring connectors. Shuts off automatically and turns back on when voltage change occurs. It also has a digital voltage display. And a voltage adjustor. (Not sure in how that affects stereo performance yet though). The light on the front bounces to how much capacitance is being used- kinda cool

I have this along with a SHURiKEN SK-BT20 and my system never drops lower then 13.5v. I'm pushing 1700w rms and my lights don't even twitch! Also the display on it is pretty cool lol it mimics an EQ. Nice product, I would recommend it to anyone.

I've had a lot of different caps and so far this is the best 2000W/RMS 4500W/MAX this paired with sound stream power cell Voltage stays between 13.6 and 14.8 at max volume this is amazing. The only problem with charging was that I forgot that the resistors get really hot so all ways wear a glove or use pliers.

Customer Testimonial

I shopped around everywhere, no one came close to the prices that sonic electronix did, the shipping was fast and all products were packed well. I even got a call from them telling me that I need a special wiring harness for my truck, and gave me a discount on the price for it.
