Which Audio Capacitor to buy? How many farad?
I have a 1100 watt subwoofer that are hooked up to an 800 watt amp. There's a chart for what farad you need which applies to your wattage but I don't know exactly how many watts my system is producing since I'm using an 800 watt amp with 1100 watt subs. Would I need 1-1.9 or 2.2-9 farad?

Caps are only used to smooth out power to the amp if a big system is set up or ur speakers spend most of there time at max watts. That being said Ive installed a 6000 watt sub setup( that's not including actual speakers, only the 2 15" subs) without a cap on a 94 neon and had no problem. The customer then bought a 5 farad cap and had me install it, there was no noticable difference.

It depends on how stout your amp really is ... so many say "1000" watts, but really dont deliver that really. I agree with the previous poster, it smooths the power out, reason is the it only gives a temporary headroom for a surge of needed power. A xtra battery combined with a cap, makes a difference more that just one or the other. Also make sure you get a isolator and proper fusing and wire (ground and positive) size are important too. My last system was not complete until I had my alternator rewound/rebuilt, since it was not putting out enough amperage for my setup. I would carefully research, and remember google is your friend ! :-)
