Overkill but good anyway.
This guy is awesome. I got this thing and it is a bit overkill for what I’m using it for, but it does its job well. I used to have voltage drops low enough to literally bog my amplifier at kick drums. Nothing dims. It has an automatic turn off, so you don’t need to wire another remote wire. The size is a little big, but it’s a 2.5 farad so I’m not surprised. It gives out a fair bit of juice. I like it.

Easy to hook up.
It works like a champ, I hooked it up to a rockerville 10-in tube speaker.

A capacitor will always be a must for car audio enthusiast. Best capacitor running my 400 watts 4 ch amplifier. The only thing I do not like is the harmonic distortion it produced…

Price and Design can't be beat
slim design for the price is great no trouble at all, just a slight small difference on the park light diming. it cant hold big low bass kicks without dimming the power. am running a 2000 watt Epic on 2000 battery cable. on regular battery and regular OEM alternator. 2016 toyota tundra.

GREAT CAPACITOR.
I used this capacitor with my subs because my lights were dimming every time the bass dropped. Very easy to install, if you don’t know what you are doing take some time and do your research because if something gets hooked up backwards you could fry your amplifier or your car battery depending on the circumstances. make sure you have the correct gage wiring for the watts you’re running. Overall I have had 0 problems with this product and it stopped my lights from dimming and did exactly what it was supposed to do. For anyone who doesn’t know, the capacitor is basically power stored from your car battery and instead of the amplifier pulling power from your battery it will pull it from the capacitor instead, saving your battery a lot of stress in the long run.

Broke in 2 months
Stopped working suddenly and the negative side connection is loose? Like the stud is loose and no there is no numbers even coming on anymore. Gonna ask for replacement or refund will update when I find out.
