I have to ask, have you first hand experience with Alumapro CAP5, CAP15, CAP50?

This is the product line that I specifically mention.

I had them in four personal vehicles as well as countless friends and family vehicles.

None of us were "disillusioned" as you state (which is not a word, but closely resembles Disallusioned found only in the Urban Dictionary).

I think maybe your trying to say delusional perhaps?

In any case, our volt meters were not delusional when they represented a complete voltage regulation after Alumapro's product was installed. None of us were delusional when we visibly witnessed light dimming to be corrected.

YES, having worked in car audio industry for a good run, you get to find out what products do not work, especially as advertised. The other benefit being, you get to find out what products DO work, first hand.

I would always recommend the Alumapro CAP5 to a 500w RMS setup, and the Alumapro CAP15 for up to around 1,200w RMS.

After that, yes, add some batteries, and upgrade the alternator if possible, its about keeping the voltage regulated during heavy musical notes to keep your power output at rated amounts.

Lol... You can learn 2 things here today, my friend.

1. Disillusioned, as defined by Mirriam-Webster (they are the dictionary people) Losing Faith or trust in a product that does not turn out to be as good as it seems or is promised.

That's true, you can use google to look it up if you like. I believe this video specifically uses the capacitor you mention.... check it out.
Now, I know This won't change your mind, and you won't change mine, either, but personal attacks are not necessary. Its just an internet forum, after all. Enjoy the video. http://www.youtube.com/watch?v=vTuJ7oz9g80

Just a funny little side note; I have a friend who bought a "Vornado" for his truck, and drives with his tailgate off to "save on gas" He will swear up and down that he has increased mileage since hes been doing it.
Although scientifically proven that neither of these remedies work one Iota, (yes, that's a real word, too) he will never admit that he spent $100 on something, and was taken across on it. I would think its safe to say that he will someday admit that he is "disillusioned" as well.

Honky tonk set aside, all valid points, Vornado's and all :icon23::icon17:


The video is a bit flawed. Case and point, the bench test really.

He's using a 15A (Max) IntelliCharger to simulate the alternator charging current to the battery.

...Wait, back up, yes, he's feeding the battery, at most, 15A to provide this test.

Now mind you the first load test is 25A. :icon14: 15A of charging, 25A load :confused:

Bench test over before it started. Also, a tight constant AMP load does not represent a musical note. Unless playing sine waves or single drawn out notes (not typically found in your average song)

You are right, you won't change my mind. Again, going from real world experience here, my own personal use of the equipment.

These caps are more than capable of creating a better regulated voltage environment for your average amplifiers. (SPL competitions need to apply here, cause we know, Burping takes Batteries).

:icon17:

As I said, the argument will wage on forever.... find me a video that proves that they actually DO work for their intended purpose. It does not exist. Ohms law says so.
we will continue the debate at that time.:tiphat:

Back to topic, At the Meca / Iasca show this past sunday in Ellicott, Md there was a guy with a pickup from Pittsburgh, PA He has the fiberglass cap on the back, and inside he is running several phoenix gold amps, he got the two Rane 31 band graphic eq's (110 volt), It was awesome to see that old school gear at an SQ show. The guys nickname, of course was "old school"

That is really cool old school processing.

No **** would have loved to see that setup and take a ride down memory lane !

Rane... nice... :-)

Remember the AudioControl EQT's? Mono 30-band equalizers? Man, wanted to SOOOO get those for my old systems, but (1) way to expensive for my college/just starting out salary; and (2) absolutely no real estate to put them without taking over the entire car.

I learned a lot from AudioControl and they made excellent processors. I bought a bunch of stuff from them. I was an AC fanboy.

Any one familiar with USD by speakerworks out of Orange, Ca? Image Dynamics came up with their own too.

Absolutely...waveguides. Unprecedented staging and imaging, but they were so big, and hard to fit in the vehicle... I had a set of audio control EQTs, and sold them to a friend, who still has them in his car. 25 years old, and still running strong.

I'll see if I can scrounge up a pic of "old schools" pickup. I didn't take any, but I'm sure one of my friends have one.

I recall seeing several pics of the ID waveguide tweets; only heard of the USD's. Either way, I've only heard good things about them.

Don't know anyone who has these things anymore. Can't wait for some shots.

http://bit.ly/ZdGlkl here is a video link, none of my buds got pics at the show... At around 1:12 in they start his interview. This is from a show in Columbus 2 years ago.
