Default capacitors?

is 1 capacitor good enough to run liek 2 or 3 amps ? still new to the audio system stuf so any input or info would be great.

this is wut i was planned on getting

is it even possible for 2 amps to go into one capacitor? and how would i go about wiring them. thanks

edit - didnt see ya there but hwo did you wire them? tahnks

sure you can put a million amps to one cap, but I wouldnt reccomend it. The capacitor is supposed to be wired in series before your power hits your amp. Usually people will place them before the distrobution block in multi amp setups. I would suggest buying the RF Cap Pass thru adapter for that cap thats pictured because it will clean up the way the wires look...

You can wire as many amps as you want to one cap. It is all about the caps capacity versus the total amp power. 1 farad per 1000 watts should be good.

Why are there two connections on each side? The ground only needs one.

i have no diea y its hooked up like that. i just needed a pic sho w u guys. i'm gonna have liek 2 800 watt amps so does that mean i need 2 caps? one for each amp. i wouldnt know hwo to wire them uo thats the thing. thanks for teh input fellas

You could run a single 1.5F cap. Install will be cleaner than two IMO.

With 2 800 watt rms amps you should use a distribution block. It basically converts one large gauge wire to multiple smaller ones. With your setup you are looking at at least a 4 gauge run from the battery maybe 0. It seems that nobody sells 2 gauge so it is not really an option. The main run goes into the distibution block near the amps, then smaller like 8,6, or 4 gauge connectors come out the other side.

twice the grounding power? LOL. actually, i would use 2 wires to ground, just to be safe.

Also, the cheapest place that I have ever seen wire (Aside from the welding stuff at Home Depot and Lowes) is Ebay. Every size in every color. Good stuff.

but gotta remember you have to have a cap with a super low ESR value. getting one that is high is basically useless. what kinds of brand do they sell on ebay? cheapest and most effective one i've seen is the lightning audio from thezeb. don't know if they still have them that cheap though.

It doesn't matter how many wires you use as long as the combined sum adds up to the correct guage for the current requirements you are going to draw. Your wiring system is going to be as strong as the weekest link.

Ideally you would want to place a cap as close to the the amplifier as possible. Personally I would run a 1 farad cap to each amp, as close to the amplifier inputs as possible.

You probably already know this but capacitors are not wired in series as mentioned above. They are wired in parallel with the amp. Wire it in series and you have made yourself a useless filter.

yeah dude, but **** stinger. really overpriced. look here: http://www.alumapro.com

they have a 15 farad cap for the cost of 2 RF caps. A 50 farad capacitor for like 400, depending on the dealer. way cheaper, same thing.

All caps are not created equal. Stinger is a very well respected company and list the ESR values for each cap. Not very many cap manufactures do this.

but caps really are not necessary if you are not running a high power system.
and they can be run either before the distribution block (just 1 cap) or after it (if you do one cap per amp)..

If you are running a smaller system (less than 1000w) like I am, then you can easily get a 1F cap hook it up before the power distribution block.
All it's for is a power reservoir to supply a little extra power when the strong bass notes hit. There for not worrying about dimming lights, or clipping.
Now if you are running a huge system like we are in the gumball prelude.. then yes, a cap before every amp is a good idea. But then again, also upgrading your alt will be the most benificial.

I did mention ideally. I didn't say the other way wouldn't work. The longer the wire you use to connect to the amplifier the larger the ESR values will be of the system.

Ideally I would have the proper size cap for each amplifier in the system. If you buy a really large cap that has a low enough ESR than more than likely if the amps are close together, the cap should have no problems running both. You really have no way of knowing for sure because most people do not have the necassary equipment to measure ESR.

You are correct about not needing a cap for a low power system. Most quality amps have an array of stiffening capacitors already inside of them. When you go to larger amplifiers its gets more difficult to get enough capacitance inside them. Usually there is still enough to operate within spec.

Before you go waste the money on any cap, up grade your wiring not only from the battery to the amp, but also from the alt to the bat and from the bat to ground. Most honda's already have 6 gauge power wires but thats just to run the cars accessories and such. Also find a good ground. If your car has a good strong electrical system then a cap is a big waste of money. Also up grade you battery (you can get a gel-cell from Wal-Mart for less than you would pay for that cap).

i'll look into that but i a;readu bought 2 digital stinger caps. will the power and ground wires for teh abttery help tha t much?

wut size shoul di use for the upgrade of alot to abttery. wut do u mean by good ground?
