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…

    • Overkill but good anyway.
Review Image by Alex Hendrix
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. ... show more

    • junk, literally dont buy this, served no benifit to anything.
Despite all of the reviews saying it didn't do anything, I didn't listen and bought it anyways. I had server dimming and voltage drop in my 2017 Civic. I bought this unit, and spent another $40 on wire and crimps to hook it in. It did absolutely nothing, still had voltage drop. If you are having dimming, what you need to do is either replace your battery with a a bigger AGM or Deep Cycle one, add another battery in the back to support your system, or upgrade your alternator. This will not fix a single thing, and will just lead to you wasting time and money. It also did nothing to improve sound quality, which was another claim it had. God bless amazon's return policy, allowing me to return this hunk of junk. All in all, 1/10 does nothing for your system. looks cool thought which is why it got that extra 1 point. ... show more

    • 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.
