which cables cant be near each other??(will cause noise radiation if put together)i gotta run some wires through my car and i dont know wich ones to keep away from others. im runnin...4 gauge (eventually will be 2 gauge) power wire for amp2 speaker wires for rear deck speakersrca cables for ampremote turn on wire for amp
yes. run your power cable on the othr side of your car from the rcas. your remote and speaker wire shouldn't affect it
NO it wont hurt nothing. Only reason you would have noise in rcas is if you got bad rcas. Only reason!
It does not seem likely that you will have a substantial problem with noise from speaker cables going through power cables and then the amp. Besides sheilding, use of capacitors on the power cable at the amp end (follow correct polarity on electrolytic types) will kill noise. A properly-rated, and connected, Zener diode is another step. Such things as antenna-leads are so sensitive that they are always well-shielded. ______________________________________... As for zener diode use, I have never heard of them being used in this application. But then, many new ideas have never been applied before. Sparky has pestered me with not one, but *two* hostile emails and is in some state of jealous frustration. He can't seem to figure how one could supress overvoltage transients using a zener (duh). If he had asked respectfully, I would have told him what I was thinking, but since he is determined to be a jerk about it, then whatever...
I was always told not to run power next to RCA cables. When I ran my cables I ran Power on one side and speaker and RCA down the other side in my car. It even says to do it this way in my amp instruction manual;Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power cables and any high power auto accessories, especially electric motors.This is done to prevent coupling the noise from radiated electrical fields into the audio signal.
Technically, running your RCA wires and power wires shouldn't cause any problems and can be dubbed a myth. However, a lot of people will disagree. For induction between power and signal wire to occur, a form of AC must be introduced on the DC power wire. One solution, if you want to run them together, is to have good shielded RCA cables and/or to separate the RCA wires and twist them (as in twisted pair wire, twisted pair wire is used in CAT3, CAT5 and CAT6 communication wire to eliminate noise/interference/induction). Another solution is distance, you don't have to have cable on both sides of the car as a 1 foot separation will do just as good. ____________ As for will s, What in the world would anyone use a zener diode for? A zener diode is used to regulate a lower voltage from a higher voltage. Example, if I wanted a pure 6 volts from a 12 volt supply then I would use a zener. Zeners don't operate well when the supply is the same as what you want out (ie, 12 volt supply, 12 volts out). Besides to find one to handle the current will both be quite large and expensive. Plain useless. Additional notes Clearly your attempts are for a good measure, but lack in the knowledge of what really happens with the introduction of induction on an input, makes your idea wrong. My pestering hostile e-mails were nothing more than a discussion on how your idea wouldn't be cost effective or practicle. It's a shame you can't take constructive critisism. I would like to point out that overvoltage transients and induction are two totally different things in their respective terms. Overvoltage transients are caused by motors and relays turning on/off. Induction occurs exactly what happens in an AC transformer. But in this case, AC isn't an issue since it's a DC power source. Granted, induction is probable, but not likely due to the insignifacant level of voltage produced plus the sheilding of the RCA cables.
