how much is too much

[Julio 10+ year member]

I have a rockford fosgate bd1000.1 amp and 2 L7 12 in. woofers, and I was wanting to put in (3) 1 Farad Capacitors. The question im asking is that too many caps or what. can you even have to many caps

basic rule is to use 1 Farad cap per 1000W system power...

no it does hurt to have too much capacitance BUT it isn't cost effective

i just hope your charging system can handle it all...good luck

How bad do your lights dim, if they do? You will probably only need one, unless you are the kinda guy that doesn't believe in too much. If one cap doesnt help, try a new high-output alternator. Readily available at your local stereo shop (usually have to order it, though). One farad per 500 watts is what I go by, but I'm not running a cap right now. I've got a JL 500/1 on two subs and my lights get quite dim. Also think of looking into another (multiple) batteries. This can help, too. Good luck.

more batteries = more load on the alternator-------- bad idea....they don't help when the car is runing

your money would be better spent in an alternator upgrade

no it wouldn't.

sure! ----- but please explain in detail why you think a new alternator is need. It's just one amp and I don't think he plays test tones all day

If your electrical system is under a serious strain, a cap is nothing more than a band-aid on a headshot. Not gonna help shit. If this is the case, a new battery/alternator combo is the only way to help it, short of redoing all of your car's wiring.

Now, if your elec. system is pretty well okie dokie while playing regular music you listen to daily, a cap can do no harm. A cap will store batt. power and send it out when the amp needs it. And yes, 3.0 fareds on a 1000 watt amp is overkill. 1.0 should be enough, but you can go 1.5 or even 2.0 if you are paranoid/upgrading later.

what i was told by this stereo sales man that really did know his stuff,,, was that one farad for every 1000 watts RMS is sufficient

well first---- a cap will always help with the peak load no matter the state of the charging system-----that's cause it is a cap. Batteries DON'T help with load when the car is runing. Alternator & batteries are slow creatures to respond to a load ----let alone it be a high speed switching load. -------

ya, but as said before he's only running one amp. he's not going to need 3 caps to provide his peak power. a nice alternator/deep cycle battery would suit that much better. and i dont think i need to repeat why as it has already been posted

please explain how a battery can help with ---------any -------load when the car is running? Explain how a battery & alt replacement is " better " Im not saying 3 caps needed but .... How is getting and HO alternator($$$$) & and a new battery($$$$$) more cost effective then some cheap capacitance?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
