Whats that AMP rated at? And how high of a load do you have it wired up to? Depending on how big of a load that amp is running at, that capacitor might be hurting more than helping. Its always a better idea to upgrade "the big 3"/battery/alternator before getting a capacitor. Depending on your amp, my advice to you would be to ditch the capacitor, upgrade your "big 3" and then look at a battery like the RedTop you mentioned, or even better the YellowTop.
