    Seems to be working good for now I have noticed that it stays on for while after cars off sometimes but hasn’t created draw on my battery yet. Does go off but takes while. By on I mean the light on screen. Over all works as is supposed to.

    I had a older one that started to go out, and the best buy car audio crew was very helpful. Oakdale, MN Best Buy is a great car audio crew.

    Useful for filtering the power going to your amp to reduce any noise being introduced. Not useful for supplying power to amps with significant power draws. But is useful in specific applications or instances to improve sound. Will not magically give you more power or fix your electrical signal. Price too high

    This was a pretty straight forward install. Best feature is the built in dual terminal block on the negative and positive side of the capacitor which accepts up to 4 AWG power wire. Working great so far.

    It's a capacitor, it holds electricity, it lets it go, not really much else to it than that. I believe my screen may be out though, so may have to get it replaced.
