^^ honestly man, you are the one who is incredably un knowledgeable here and not anyone else, i wopuld like to know where you are getting any of this info from?
This info comes from knowing what is actually required to induce noise into a signal cable. A steady magnetic field won't do it. If it did, you would get noise from the speaker magnets. The EM field from you power wire firstly isn't very focused and secondly is not reversing it's polarity constantly. The result, very little chance of EMI. Factor in the basic shielding on any decent RCA (still costing much less than $150, more like the $20 range) and the ripple left over from the rectifcation that got past the battery isn't of any concern either.
first off all, anything passing power though it cases elctro magnetic fields around it, smaller guage wires obvisioully much less then a 0 guage wire but both will still have magnetic fields around the wire itself, by strapping or zip tying your rca's to the power wire, the magnetic field gets into the rca cable causing system noise (ie. alt whine and etc)
As mentioned above, if you use a chassis ground, it is flowing the same amount of current as the power wire. The simple presence of a mag field does not amount to noise. It has to be a fluctuating field and a strongly fluctuating one at that.
now lets look at the alt. itself, how do you think the power is created inside the alt, it gets spun by a pully from the engine, which inside spins a series of magnets which then creates energy and is then stored and sent through a series of diodes (sp) and rectified and altered from AC to DC power, exact same concept
Exact same concept as what? WTF are you trying to compare this to? Anyway, the output is still DC, albeit with a slight ripple that is most always filtered out by the battery being wired in parallel.
and unless your using $150 and + RCA's which can prolly be strapped to a 0 guage, anything else it is very likely that it will pick up interference, which is why rca's are always placed on the oppoisite side as the power wire
Always? Really? Care to back that up? There have been several very well respected and successful SQ competitors that agree fully with what I say. Don't believe me. Fine, but you don't have a leg to stand on from a science or practice stand point. My RCAs (Stinger Bullet, $20ish a pair) are run right beside my 1/0 power and ground cables. No noise in my system, whatsoever. I guess my vehicle just defies your physics. Or maybe you're just so lock in on the myriad myths that have propagated from the early days of car audio that you don't actually care about and clearly don't understand the physics behind what you are talking about.
Whatever, dude.
come back with a reply once you have a proper education in what your talking about, i wouldn't be so hard if you didn't flame everyone else who disagrees with you when actually you were the one who was wrong all along
Look mister high and mighty, why don't you pull your head out of your *** and bother to listen. I DO know exactly what I am talking about. It is you that needs to learn. Everything you have spouted has a basis in science, sure, but it is only part of the total. The part that actually matters is the part that you are leaving out. Not sure if that's because you don't understand/know it our you just want to make yourself seem like a smart guy on the 'net, but I'll give you the benefit of the doubt and believe that you're just ignorant.
there i just provided you with the physics and science of it to back it up, something you cant argue with seeing as though i am going to school for this shit right now and there highly trained professionals instructing everyone this and there not gonna lie and give us bullsh*it
What exactly are you going to school for? If it is an installer school, call BULLSHIT! They are only propagating myth. They do NOT have any physics to fall back on, PERIOD. There are people out there with much more technical understanding of electrical theory that will be more than happy to tell you that the car audio installation business is rife with BS. You probably believe that all installs need a cap and that adding one will make the bass "hit harder" too, right?
Which is also why it isn't recomended to run large guage wires by or near ecm's or abs control units
Someone should tell that to Dodge. My ECU is right between the battery and the electric cooling fans on my car. The ABS brain is right next to the fuel pump. Ever heard of a Faraday cage? Look it up.
