Review: 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.
Review: It work great
