Metra Tsunami LITEWAVE Series PP912UM-CAP

With Tsunami capacitors, you'll never have to worry about getting enough power to the amplifiers in your high-end mobile audio system. This Lite Wave Series 1.2-farad cap stores up a reservoir of power, and delivers it exactly when your amps, subs, and speakers need it most. The blue LCD meter shows you just how much juice your cap is putting out. Blue flashing LEDs add a cool look to your installation. An audible warning lets you know if the voltage is too low or too high.
