New here. My set-up!

[mxking225]

So im new here! As you can tell by the name lol. Anyways, here are some pics of what in my ext. Cab. 2-JBL 12's with a JBL 300.1 Amp. Tsunami 5 farad Capacitor, and the other JBL amp is the 301.1 that goes to my mids & high's. I'm 16 and i did this all myself.

wow, thats a nice install. I'm not a big fan of caps, but thats nicer then my first attempt at fiberglassing. good job! *thumbs up*

[01cherryreds10]

Sell the cap on eBay to someone who doesn't know any better and buy like, 25ft. of 0 gauge wire and some terminals. The dimming will stop (unless you have a crappy electrical system right now), and you should be able to make more power out of those subs if I'm not mistaken.

Sick system none the less!

[KillaCam213]

Not a big fan of caps neither but damn good job installing!

Judds can we get someone to sticky that?

[mrkenny]

buy you a yellow top optima... and throw the cap in the trash

[mxking225]

Actually, I have both. You see the cap there in those pics...And you see the fold down seat over there? Yeah, false.... Here's whats really behind it:

And also, I work at a speaker shop who owns a full Termlab System. I read an article like that before, so we set up the lab and tested and tuned. I tested with 0g wire, like 120DB. With 4g wire, the battery, and the cap... 131.4DB.

first thing you'll learn, and i'm not being a dick, just telling the truth, don't run a cap unless you know one of the good reasons to run one,(i don't know them), more stuff.....don't argue with: paint toad, dansolow, juddspaintballs, imperial, captainmorgan, and a few more, but just don't do it, it'll suck. no-one will like you. nobody cares if you work at a shop(unless we get stuff at a discount) don't run kicker, you'll catch shit. don't run little power wire, you'll catch shit. don't run dash speakers, you'll catch shit. don't run any speakers that aren't round, you'll catch shit. i mean do that stuff if you want........we all like to laugh, but just know whether you care or not, you'll catch shit. and just because you should know. stickied threads and the search button are your friend or...you guessed it, you'll catch shit.

now, nice glass work and good choice in brands, i like your set-up. you should post it in the sound system show off, and welcome to the forum, it's a great place after you get past the assholes. best of luck,

Austin

[mxking225]

Thanks for the tip. And yes, i too laugh at people who run kicker, so no worries there lol. As for the dash speakers, i have some in, but will be coming out soon lol. I have several other hobbies that i am on forum's for, so i know all about the search button. And i run 4 gauge, so thats not small.

BUT, thanks for the compliments. And i'm going to keep running my cap.

[lwrd93]

im running a cap now and my lights still dim.. those things are shit im gona do the big 3 soon and chunk that thing in the lake.. or ill sell you it :-)

[OneLowSdime]

looks really good

[danssoslow]

Anyone here know the definition of Farad?

[David12460]

google is your friend.

The farad is defined as the amount of capacitance for which a potential difference of one volt results in a static charge of one coulomb

how aobut this? 1 12.. 4ga wire.. no cap.. 1 batt( in the front).. on a TL

[mrkenny]

THATS GOTTA BE A JL W7!!!!!!!!!!!!!!! ya???

[Speedy2222]

no.. it's not

no. the sub is made by atomic. it is one twelve. before then, i think he didn't know what it was...

where'd you find this info at.. nvm i thought i didnt put it in my post on here

however, i still dont know what model it is or the specs

yeah. it's your stuff after all.

Now we are beginning to get somewhere. Now lets define what a coulomb is.

The coulomb (symbol: C) is the SI unit of electric charge. It is named after Charles-Augustin de Coulomb.

Or as a measure it is an amount of electric charge carried by one ampere in one second.

So a 1 farad capacitor can hold 1 amp second of electrons at one volt. In an automobile, your typical 20V rated, 1 Farad capacitor will hold 13-14 amp seconds worth of electrons. Can noone see where this might be useful in a car stereo?

[PandaS10]

in spl competition applications only. after all other precautions have been taken, and you want to run a full 16 volts to the amps for only a few seconds at a time...

[juddspaintballs]

dan, as the ROE link i posted explains, the voltage in the capacitor drops immediately as it discharges (which i know you already know). it takes a lot less than 13-14 amp seconds worth of electrons before the battery is supplying the necessary amperes. at that point, the capacitor is just a drain on the system as it tries to recharge. it delays the electrical system's voltage drop after the capacitor, but delays it's voltage recovery too.

i know you know more about electrical theory and application than i do. can you refute anything i said or what richard clark said



i'd run a capacitor if i really wanted to rework my system. they're GREAT for smoothing out electrical dips and peaks which makes them great for SQ setups. not so great for SPL though

[PandaS10]

****, i was so wrong.

WHO CARES IF PEOPLE GIVE U SHIT, man what happened to building a truck cause u like it, i could give a **** about what people on the forum think about my truck let him do what he wants, so the cap might not be the best choice, the correct post would be to make the argument and information available to him instead of telling him hes stupid and u dont care about some shop he works at unless YOU get a discount


ur entire post sounds like ur talkin for the entire forum i personally not only dont even recognize ur user name but its blatent u havnt been here long, ide say get urself out of noob status before you go about telling people what they can and cant do without "catching shit"

You hit on where i am going with all of this. It would seem that everyone has assumed for a long time now, no doubt by hungry merchants and the increase in the subwoofer market over the past ten years, that the Cap is primarily used for increasing subbass output.
Sure, where sustained bass notes are used, the cap will quickly deplete and spend the majority of the note charging; but with non synthesized music, there are many transients where the cap can be very useful in supplying the quick bursts of power necessary to correctly reproduce the music. Then there's the issue of smoothing out the power supply. With an electrical system strong enough to support a given system, the cap won't hurt a thing, and can supply the moments of high demand that the biggest of alternators could not supply. I agree that its usage is typically as a crutch for a weak electrical system, but we can't let the usage in these situations determine the cap's worth.

As far as Richard Clark goes, I do look up to the guy on most things. Hell, something I read that he wrote a long time ago in CA&E has stuck with me forever; it's almost like a mantra.
When it comes down to it though, I believe alot of what he writes is a well documented attempt to prove his opinion or to sell something. Dan Wiggins has done the same thing in some of his write ups. I'd bet Clark and Navone made some booku bucks on those noise gates they used to sell. When was the last time you heard of anyone using one a noise gate?
As far as his opinion on the issue of the cap; I looked it over, but the title of that thread was enough for me not to look too deep.

I say the cap has its place; albeit a small one.
