nice man. i want to get a jbl amp. so expensive though. need to save. have you heard the memphis subs? they are like 400 a sub for like 12" or so. definitely would love to hear someone with those speakers. i only have 1500 watts of bass. it's fine for me though i guess.

 

You sir, are an idiot. Please know what you're talking about before posting.

Yes I've own "systems"...multiple ones. Ask anyone here that knows about my installs. A "cap" simply releases a short burst of power to your amps blah blah blah blah right? ok...so what exactly do you think to recharges that cap? that's right, your stock electrical. your alternator needs to recharge that capacitor after each discharge. do you think that power comes out of the air?

most audio systems that experience major issues with dimming/idle issues is due to weak electricals...bad grounding being the most common. a MAJORITY of your problems can be fixed by upgrading the 3 main vehicle grounds...not by using a "cap". those are just bandaids for a problem. i have buddies that compete in IASCA running upwards of 10kw of power, and none of them are using 'caps'. I've ran 3 amps at one point, and experienced NO issues.

Point being, caps are useless. But feel free to reply via PM or hell, post a thread in the audio room. I don't want to ***** up the OP's thread.

 

You're stupid Alpine, JL audio, JBL, RF; you don't have enough experience then cause eclipse > any of those and rainbow > infinity speakers. You say you have experience but all your audio you have "experience" with is all main steam but you don't have any experience with the better audio of the non-main stream audio. If this was in the audio section, you would have looked like a fool, but then again you already accomplished that. So before you go and place your knowing-all knowledge and call ascendantmax out, do some research then come back and talk. Until then, I said good day.

 

Do you Really believe this crap, or have you just been a victim to massive aggressive marketing ?

A cap, really ?

The best he has heard in a year of installs ? Does he only average 2-3 a year ?


It is simple ... Prove it. OR ... purchase some quality amplifiers and trust the ones that are in there. You Do realize that there are caps in very single amplifier, right ?


Do you both live in a cave ?

 

and this is why you go to the audio section when you have an audio question.

 

quoted for the truth!

 

I am relativley new to this car audio **** but I do work on electronics at work. I know that a cap is useless, I would never waste my money on some **** like that.
I am about to upgrade my stock HU in my 04 SE with an AVIC F90BT. I already installed subs, JL 600/1 amp with a JL 12W6 sub.
I purchased the sub and amp separatly off ebay from one of those stores, i know they arent supported by JL but I saved $600 from the crutchfield price. They work great, I can't wait to put my new HU in, I'm sick of the stock HU skipping my cds. So now I am going to spend a bunch of money to get a nice HU.

 

I'm not new to audio but i'm amazed at people saying Caps are useless.......
I could stand corrected not trying to be a know it all or smart ##S but correct me if i'm wrong.

Caps are good if:
1. you are truly pushing 1000+rms
2. @ a low ohm rate maybe 0-4ohms
3. and your speaker does 1000+rms
4. can push a low frequency maybe 5

yeah it is true that if you do ground your system good you won't get the dimming effect but what a Cap does is it stores power and when your system really hits or you are looking for continuous power to your sub. this also helps your sub because it won't damage the sub.

when you don't use it when the sub is hitting yes your altenator and battery can sorta handle it but its not made to handle additional wattage up thats not constant.

Just my 2cents and i have been doing this for awhile.
The brands you guys are naming are yeah the normal but do some research if you are looking for good subs and radios.

My personal setup is:
Pioneer DEH980BT
iDMax 12D2V3
Kicker ZX1000.1
Alpine SPX17Pro 6.5 Component Speakers
Kicker ZX650.4
Stinger 5 Farad PRO Hybrid Capacitor

 

1. i have upwards of ~1600 watts on tap and still not using a cap. it doesn't really matter how much power you're running, you still don't need a capacitor.
2. impedance isn't a variable. it's just what load your amps sees depending on the wiring/voice coil configurations.
3. again, speaker wattage rating still isn't a variable for 'cap usage'. the rating is what the speaker is tested to handle thermally continuously.
4. frequency isn't a variable either.

how will this damage your sub? a good ground is usually the fix for many voltage issues. for those running very high powered systems, a high output alternator is the usual route, not a cap.

the cap will continue to charge and discharge, just the amount of discharge will be different. so the cap isn't really "turned off" when you "don't use it."

if you do some more research then you'll know there's more out there than kicker, alpine, etc. i mean in theory a cap sounds great. but most of that stuff are marketing gimmicks.

 

Being in the 12V industry (a bit over 20yrs and 7+ of my own shop) I would not sell a single person a cap. If I had zero morals and ethics, I would push em all day long and have a considerable amount of pocket money at the end of the week. It's a ploy to sell more products. Worked very well for many years and as you can tell by this thread many are still victim to it.

But amplifiers that are properly designed, implemented and well built - you will not feel the desire for a cap.

For reference, this car that I did a few months back does not have a single capacitor outside of the amplifiers themselves ..



TWO Billet B-Fours/Stage III/Kimber (paper rating: 200 X 4) - 2 1000w power supplies.
Billet 2200 (Paper rating 200 X 2) 1000w power supply.
Billet 4100 (Paper rating 100 X 4 - it is bridged - 300 X 2) 1000w power supply.

At IDLE these amps can draw approx 8amps.

Two OEM sized batteries FROM SEARS and ZERO ADDED CAPS. Dimming lights ? lol no sir.

 

CAPS ARE USELESS!!

Unless you want your system to look like it's really doin something.

 

Im installing an aftermarket stereo and two rockfords and an amp. If i split the wires from the amp and wire it to the radio will they sound better than with the bose am? Plus i have my subs n amp hooked to a converter. Should i run them to the deck for better sound?

 

infinity have the ebst sound, but no1 is answering this guys origininal question haha

 

You ARE kidding I hope.

 

What's with all the hatred towards caps? They show up in damn near every electronic item you can buy. Mabye it should be changed to big colorful glow in the dark caps are useless.

Also, I have some random infinity speakers for rear fill I haven't heard any complaints

 

Caps..Infinity..Rear Fill...........Fuel to the Fire
