Anyone use a Audison Cap?

[pimp86LX]

hey folks. I've looked around the web quite a bit and I can't find an english site that referrs to this cap. Has anyone used one and if so, how does it perform? any issues? etc.. etc...

Audison Connection
BSF 08
.8 Farad Cap
20VDC

Audison makes some amazing stuff... Can't say I have used one myself, but I know people that have, its a good cap. IMO i have yet to see a bad product from audison

meh...caps are worthless in my opinion....theres really no need for them

[crazykamper]

what the hell is a cap sopposed to do? lol.

[2ndGenGuy]

It stores power like a second battery. When the loud, power-sucking sound hits, its supposed to supply power to the amp and keep the strain off of your electrical system. Basically keeps you from blowing your alternator from constant strain.

the guy at the audio store said that if a amp goes under a 10v limit it could blow up...im not sure since he wated to sell me a cap but i said i could find one for half the price he wanted...i think it was like 125 for quality cap

caps are worthless man! they're just for looks and a conversation piece. if youre really concerned about your alternator blowing out, i say the best bet is to invest in a higher amplitude alty. plus if these things blow up....they burn everything in your trunk with it stupid shit its fill with. its gay trust me lol.


plus you do know that there is only two known companies that make them right? they're all the same! so there really is nothing to compare. if you buy a rockford one and an audison, look under them and you will see the same number stamped on them or something similar. the only thing that changes between these is the actual cap. if its digital or not. and even that, the only thing that changes there are designs. completly useless, i used to sell them :D

[crazykamper]

lol. good point monkey. thanks for the tip.... one less thing to waste money on.

It also supplies a cleaner power, instead of going up and down in voltage all teh time it supplies a very consistent amount of voltage, which is good when you speaker is mid-excursion and you lose a little voltage, you lose a little power to the sub.

I got a $50 one, its a full farad, its no high quality name stuff, but it definately does the job a capaciter is supposed to do. Esp with the power im running it keeps the car from dying when its cranked at idle at 800rpm, the tack varies between 7-800 instead of shaking the car below 500 now

edit: and the annoying dimming light problem goes away too

Aye. I agree with the fact that a re-wound alternator would be a great solution, a cap does still serve a purpose. It may not improve sound quality per say, but it will add a layer of protection to the charging/electrical system and audio equiptment. Maybe when my warrenty expires i'll throw in a nice yellow top battery and a HO alternator.


p.s. I'm installing in the morning, we'll see what happens.

I wouldn't go as far as to say they are worthless, they are very efficient power filters. While a higher output alternator is great, you also want clean power going to your amps and eventually reaching the speakers. Clean power can go a long way into extending the life of your amps and speakers. While an amp won't blow up from being undervolted it most certainly can get damaged if it happens often enough and of course feeding unclean power to the speakers will cause a slight wobble wich will eventually warp the path the speaker travels up and down on causing that horrible scratching noise some of us have had to endure at one point or another. Upgrading the alternator is always the best solution but having the cap to act as a nice safety net/filter won't hurt.

I used to sell car audio aswell... And I know from experience that lots of caps are shit. There was a report in I believe car audio and sound a while back, they disected a bunch of caps, and most were actually filled most of the way with sand or something instead of actually being usefull.

But a good cap works quite well. I noticed a big difference with mine. Especially if you aren't running a digital amp, the strain on your charging system is even worse.

i do agree that capacitors are a great lil extra protection device. but if the only thing you have in a car is a $200 HU, $200 amp, and an $89 sub.....$100-200 is way too much to spend on a freaking cap. just my opinion the only way i would spend money on a cap...and thats a big IF....is if i had a shit load of money invested into a show car with a sound system...but even then i would opt out for two yellow tops and an isolator. i dunno...its just me

on a side note: caps are only made by two different companies here in the us. so all the one farads are the same thing. the only ones that are different are the ones above that. so if you want to compare caps....just buy the cheapest one thats one farad...no point in comparing. just price is different.

hehe thats funny. btw this one is german i think.....anywho, 8am saturday here goes the install, lets see if it makes a difference.

[mkymonkey]

lol have fun! hahahah

[pimp86LX]

welp....i have to say it turned out quite well.

Few glitches i ran into, ie) being 100% on wiring. The stupid manual so poorly translated and lacking diagrams, but everything went ok.
The charging stage was rediculously slow due to the 10K resistor they sent :S I didn't have any 1k @ 1w so i used their's :rant: The manual said hold for 20 seconds on battery. I checked repeatedly with a volt meter every 20 seconds until i reached my ~12vDC.
I also got slowed up when i had to run out for spade connectors and some 8g wire :S:S my town on a saturday morning is sooooooo bad. I hope to never repeat that.

The result. It may just be in my head, but everything sounds cleaner and the bass hits sound much more crisp.

pictures in a minute!

[HostileJava]

If it sounds like it made a difference to you then it was worth it. I don't have any amps or anything in my van and I was thinking about adding a 1 farad cap I have laying around just because I'm a freak like that about getting clean power.

These are in no particular order:

Yeah, i know its messy. looks isn't that important to me though....now if it were a car for show.......

[Hash_man_Se_i]

Looks good^&^

And I do agree... I had a shitload in car audio in my car, and when a chance came to buy a good cap for $60 I couldn't go wrong.

[FyreDaug]

Yeah man I spent 50 bucks on a cap, and some of the resident Audio & Security guys may remember my carputer system I had in my last 3g. Ive always been an audiophile, and I only spent 50 bucks on a cap. Maybe its not the best one, but its a 1 farad cap, its big, digital volt reading and it doesnt dim so much now. My AC inverter also has a power read out, and it would seriously jump from 14ish to about 12 with full boom. 2V, lets say 1000rms @ 14V, if you lose 2V thats 143W you lose because the voltage dropped. Now if you throw a cap in there and (in my case at full boom it drops maybe 0.3V) it keeps me from losing less than 22W of power. Thats a big difference if you ask me. Caps are worthless? hahaha its better for the speakers because the power doesnt change during its excursion, and you technically get a little more power out of it.

However, one thing I should note, is that its been proven that DOUBLING the RMS wattage gains you 3 decibals. Heres a little chart explaining it, if by chance you are a member of offtopic.com heres the thread http://forums.offtopic.com/showthread.php?t=2641883

lawl, if you want some reading material. So that 143W difference PROBABLY isnt making anything noticable for how loud it is. But clarity wise, I would imagine would be better, where you give it 1000rms you have no more than 3% variance in the power it recieves. If you are varying 14% like the example above what would you take?

Thats the reason people say caps are garbage, because they dont know anything

[FyreDaug]

Sorry thats my take on everything, take it as it is I mean no offence to anyone. My experience has just taught me otherwise

EDIT: Maybe I should mention its better with higher powered systems, something <300w rms its probably not needed. I run 1050rms (275w to each MB Quart speakers) and 500rms to the single Type R. Still hit 143.7db with the cap, didnt see it before the cap.... 143.7 is apparantly a non-legit number because single Type R's never get that loud.... Either my box is awesome, I got a lucky sub or the reader was off... But the same reader that read my single type R in my ported box read this guy with 2 10" type S and he got 140 something... I dunno, my system sounds amazing with that power going to those speakers
