I think do the problem i am having with my voltage meter flickering my friends told me to buy a capacitor. I am running a 500w amp right now to one 12" sub. But i plan to run another amp for the interior speakers soon. Question being will a full farad capacitor be to much for my 500w right now(is there any harm done). I was told a half farad would be good for the 500w, but i assume i will need a full farad for the two amps total of about 1200w. Can i go ahead and purchase the full farad now, since i need a capacitor anyways? Thanks

 

Yes, doesn't matter how many Farad capacitor you have. The one farad would be fine to get now. All a capacitor does is store power so when the Bass hits it takes from the capacitor first and keeps things like voltage drops and strains on electrical. Plus your amp will distort less, so is good all around.

 

Sounds good man. Thanks For the reply

 

IS a 2 farad to much for me? ebay has some great prices on these.

 

There is no harm in buying a larger capacitor ever, except they usually cost more. Buying one that's too small will not fix your problem, and that's usually the issue. I would buy atleast a one farad cap and hook it up to your sub amp only. Don't hook it up to you full range amp as it will not do any good. Only bass really uses power in small burst, which is what a capacitor is designed for.
