My Tunes.. Ok, so I wanna show off a little.
 

Well, here's my sound setup! :shifty:

Panasonic CQ-C7401u Head unit
With 5v Pre-Outs, CDr/MP3/XM Ready

Audiobahn a8000t 800 watt RMS Mono Block
Pushing One 12" Infinity Kappa 12D VQ (400W RMS 1600W Peak Power)
Custom Ported box being built.

Infinity 7540a 520 or watt 111x4 RMS power
Running Tsunami X154-17 RCA's
4 Infinity Kappa 572.5cf 5x7's With adjustable tweets

3 Farad Power Acoustic Capacitor
4 Gauge wire throughout

I'll try to post some pics when the box is finished and I get everything tightened up and nice & clean! :pepper:

sweet dude! post the pics with every thing done!

how do you like the 5x7 infinitys , i have the same set but i was kinda dissapointed in them. just wondering?

Do you have a Sub running along with your 5x7's? I'll tell you now, Infinity Kappa's, and Reference Components don't have much if any low's so, you have to have a bass line to go along with.
I can crank these baby's up all the way to 35 without ANY distortion and they sound crystal clear.
I'll tell you, if you don't have a sub these speakers alone would make your ears bleed....

I just installed four Boston Acoustic 5-1/4 rounds and they sound great...also using one 10'' Rockford P1 Punch with a puny 250W amp and it makes so much damn bass I can't see out of any of my mirrors. Your setup must be the shiz!

You don't mean me do you? my system sounds good but is nothing to look at.

How to you like your Capacitor? Ive read mixed reviews on them, some guys swear they help while others say they do nothing. I have Punch 800a2 bridged on a Punch Phase 3 12.

They do absolutely nothing for a stereo that already has too much draw. You are trying to power up another source when you already cannot feed enough current draw to the amps. Simply a waste of money and it will kill your alternator faster than it would without it. Simply put, a better battery and bigger alternator is the method to do it right.

Mine doesnt have too much draw. My lights barely dim. I was just wondering would this help me sound a little louder/stronger.

I agree to a point. I did get a new battery & alternator, BUT I still wouldn't run a system without a Cap. Before I got my cap it destroyed my stock alternator. It got to the point that when I would reach 2500rpm before a shift all of my lights would dim severely. **(that was before I added the 520 watt infinity)**

So, that should answer your question.. Spend $100 on a decent cap you probably wouldn't need anymore than a 1.2 or 2 ferad cap and in my honest opinion, it's worth it..

Actually, im going to be getting rid of my 1.2 ferad tsunami as soon as the 3 ferad comes in (Tuesday) so, let me know if your interested, i'd prob. let it go for like $40 + s/h. I spent about $150 less than a year ago for it. Still in perfect condition.

-wnracing :shifty:

I'll put it to you this way, My old Kappa sub rattled my rearview mirror a bit, and basically made it impooible to see out of.. With this new sub and the power going to it, Within 2 minutes of the first song I played it completely knocked the rearview off the windshield I had to get double sided tape to re-secure the rearview! :clap: :clap: :clap:

And like I told gillz, the components scream so loud that without the bass from the sub to even out the sound they will literally make your ears bleed....

So, im not going to have any hearing left when im 30yrs old... Who cares right?!?!? :loser:

Actually they store their own power and give that extra juice to the amps when they need it most, keeping the stereo from sucking the alternator dry. I do still agree that a better battery/alternator is the best choice, but you are still better off with a capacitor than without.

Ok, well Everything took a little longer than I thought it would, but Im happy!

Let me know what ya think! :pepper:

The box is a Ported 2.25CuFt. With the LowQ Pole insert in the Sub. I had to re-secure the Mirror with the last sub, and this sub had already knocked it off the windshield again!

They do store the power, but where does it come from? It comes from a source that already has trouble keeping up with the demand. And it takes about a milisecond to charge and a milisecond to be empty again. Caps are worthless in ANY situation where you are pulling more than you can supply.

oh man almost a month later i forgot this whole argument ha ha.

The amp isn't always taking more than the elctrical system can allow, only on the beat while the sub is hitting and all your lights dim. And a properly sized capacitor that is correctly charged doesn't actually release all its power, only what the amp needs extra. It is called a capacitor because of it's ability to release large voltages quickly and let the amp not draw too much on the elecgtrical system. And how can you argue with results?


anyway wnracing your setup looks nice and I bet it sounds sweet. You thought about tossing some dynamat in there, I love me some dynamat.

I can argue with this silly statement because I used to compete in MECA, SLAP, and IASCA, with a beretta doing 145 with a single 12 and 1800w with everything in the trunk. I had state record in my class, 2nd place at midwest finals in iasca, numerous phat 12 tropheys, and numerous WI, IL, MI tropheys for finals. and I had an s10 that took 5th place at world finals in sound quality in 0-300 basic consumer. Beretta had resonant engineering xxx 12, and resonant engineering 35.1d LE. s10 ran phoenix gold and mb quart. and yeah, neither had caps.

Oh and to prove the point...

Ok so you've got 3 farads available. That does ABSOLUTELY nothing on a 12v system that cant supply the problem in the first place. The main idea of having a cap is to even out your voltage. A capacitor does not replace that for a source of power. Again like the JL w7s, you will not see them in an SPL orientated vehicle. Why you ask? They hurt you and for the price of 2 fareds (150 bucks for both) you can have over a billion farads out of a 12v 100 amphr deep cycle battery for the same price. A 12v 100a deep cycle will hold 4,320,000 Joules, and your 3 caps hold 432 Joules, given if it is fully charged.

(all based on 12v)...
In physics we all should of learned that Joules = Watts / Seconds so change that up to Watts = Joules / Seconds
w = 432j / 3s (ill give you 3 seconds of "the perfect world" without voltage drop, full power from the caps, and free of the other electronic mumbo jumbo that causes you to lose power in your audio application)
so your wattage from 3 caps in a perfect world = 144watts, not including your 70% effeciency from your amp if its class D, or 50% if its A/B, voltage drop, power loss, ect as listed above.

Now with your normal autozone deep cycle 100a 12v battery, again ill give you the benifit of the doubt and round the number down to 1 billion farads which will equal 4,320,00 Joules. Ill spare you the math on the rest of this and just point out to you why the real SPL orientated vehicles use banks of batteries (with copper bars) instead of banks of capacitors.

:yawn:

oops my bad I forgot mattj can't be wrong and knows everything about everything!

Over a month after this first came up, i'm pretty much over this argument and i'm done because I know the omnipotent mattj always has to get the last word in anyway.

I can be wrong, and I have been before (though very rarely...:) ). And there are plenty of things I dont know. Car audio was a HUGE hobby of mine before I bought my mustang and I disagreed with what was said about a cap, and you brought the argument. I came back and proved a point explaining the situation, and your side of the argument is "oh mattj knows everything and is always right."

Actually my point was that you always have to get the last word in, even if its a month later, and that I have better $hit to do than sit and argue a month old argument.

im still interested in hearing your side of this on why a cap is useful...

Wow, who gives a $hit? Some people use them and some don't I personally think that it is a good thing to have, if your opinion differs then good for you! Gotta love it when a thread get's hijacked! :punk:





:bash:

Yea and by a mod too.

What the hell is a cap?

...

I'm going back to my hole now.
