anathema989 is infamous around these partsanathema989 is infamous around these parts



ive been told several times to screw getting a cap and get myself a bigger altnator. I'll have my cap installed in few hours today and let u knw if any difference is present. my capacitor guide is as follows; lol 500 watts = 500k farad or better since 500k is 1/2 farad, 1 farad for anything between .5 and 1. a 2 farad will do you justice i hear. scosche is like the 1st 2 properties on monopoly dnt buy a cap from walmart. so yes u need a cap. the ppl who make them say so!

Not so much.

"The people that make them" would have you believe their wonderful car audio capacitors can somehow defy ohm's law and the laws of physics too .

While there are certain things a capacitor can do when used correctly (even out very slight ripples and reduce noise), it cannot make up for severe shortfalls in your vehicle's electrical system. Saying they are anything more than a band-aid in situations where an anemic alternator or poor electrical paths are the weak links is false information...I had a very wise 17 year old audio salesman tell me "You'll be sorry" and predict dire electrical catastrophes for my Jeep with 1400 watts RMS worth of system draw, and after several years of running this system without a hitch I'm still waiting .

To be clear I am in 100% agreement with the articles premice. I usually always just upgrade the alternator and the big 3 as suggested. However, I have found myself in several arguments with electrical engineers that maintain the cap is not a bad way to go for cheaper upgrades. One engineer even showed me his truck with the caps off, the lights dimmed and severe stress was on the system when they were off. He added 2 caps in and voila his lighting woes were gone. I was literally shocked as I have never seen this work before ever.

So, that really has me scratching my head. Is his one application of it actually working a one on a million thing? I see some people listing knowledge of ohms and physics, a more detailed analysis of this including drawings would be awesome so I have some more ammo to go at these guys with!

In the meantime I am sticking to my guns and saying caps = junk.

IMHO the EE example is the exception that proves the rule. Seriously there is such a narrow band where caps are truly effective.
