A great sound system needs a great capacitor because high-demand audio setups can place extra demand on your car"s electrical system. When you need power, especially for booming bass and soaring highs, this 12 farad Vector-series capacitor will have it at the ready. And it"s got all you need to make sure your system sounds awesome and stays safe: a blue digital voltage readout to show you how much power is available, electronic polarity protection, and an over voltage protection circuit. And this won"t just make your system sound great – it looks great too, thanks to the flashing blue LED with printed Lanzar Vector logo. Packaged in an aluminum tooling box.
