Q:like in movies how do you connect like some wire to start the car? also which wires? I'm curious not trying to take anyone's car.

Modern cars cannot be started that away. The older ie 1974 and younger can be.

Q:Im replacing the factory rear speakers in my car but cant figure on which wires are positive and which are negative. I went on a site for impalas but the color wires they have listed are not the same color wires in my car your help will be appreciated.

Left Rear Speaker Positive Wire (+): Brown Left Rear Speaker Negative Wire (-): Yellow Right Rear Speaker Positive Wire (+): Dark Blue Right Rear Speaker Negative Wire (-): Light Blue

Q:Consider a copper wire 1 mm in diameter providing the power needed to run an appliance drawing a 4.8 kW at 12 V. Assuming that no heat is radiated away from the wire while the current flows:A. What will the temperature of the wire be after the current has run for 1 second through the wire?B. What will the physical condition of the wire be at that time?(The wire was initially at 20 degrees C)

Assume the wire is 1 meter long. Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m resistivity Cu 17.2e-9 Ω-m or 17.2e-6 ohm-mm R = (17.2e-6)(1000) / π(0.5)? = 0.022 ohms Appliance current is 4800/12 = 400 amps Power is I?R = 400? x .022 = 3520 watts. Problem, this power is at a level almost as high as that of the appliance. In other words, the wire is too thin to sustain that power level. .

Q:I am wiring a sony xplod amp up in my car and need to know what the skinny blue wire goes to. Any help would be appreciated.

its the remote wire. it goes from your amp to the back of your stereo deck. if you have an aftermarket deck ( which i would hope you do) there will be a wire labeled that says remote wire. connect the blue wire with that wire behind the deck. the whole purpose of the wire is to tell the amp to turn on and off with the car.

Q:Hello everyone! I have what is probably a very simple question.I'm not exactly a radio expert. So my question is this:Is there a difference between copper wire and antenna wire (copper as well)?

Antenna wire has a steel core to reduce stretching and breakage.

Q:I have a 5 pin ignition. I have Black and red wire coming from behind the starter.Yellow wire on the other side of the engine that is connected to the magnet by the fly wheel.Where do I put these wires in the ignition switch. ____ ____ __

You need to hook three wires into a five terminal switch? You aren't helping us much with any usable information. The yellow wire is the kill wire from the magneto. The black and red wires are hot from the battery and feed to the starter solenoid, assuming the switch has a start position. You need to check each terminal on the switch with an ohm meter to determine which function it serves and test the black and red wires with a volt meter to determine which one is hot now. Better still, why don't you specify the make and model, even the serial number if you can get it, and ask if anyone, including your local dealer, has a wiring diagram for that particular machine.

Q:How do current carrying wires produce magnetism... Explain, give sites and clarify.

i'm uncertain we've a sparkling theoretical answer to this in spite of the incontrovertible fact that it relatively is a demonstrable actuality that shifting expenses have an result on different shifting or movable expenses.even while there is not any internet fee glaring it relatively is summarized as magnetism

Q:What exactly is 6 AWG stranded grounding wire usually used for?

It okorder /... click on the bottom picture the grounding wire is indicated. there are many pictures here images.google.ca/images?hl=ensou... Guru

Q:I spliced the stereo wires to the adapter to plug into my car. there's 2 extra orange wires in the adapter. There orange it says there for illumination and the dimmer. What should I do with them? Did I get the wrong one?

Those two wires are useless. Usually I have 3 wires left over. Illumination, dimmer and a blue antenna wire. Your good to go.

Q:I no longer have enough 0 gauge wire would it be bad to use 0 gauge power wire to the amp and 4 gauge wire to ground the amp?

all okorder /... or going into your audio dealer store asking for 3 to 5 ft of the 0 gauge wire for around 15 to 20 dollars at the max. you can also asking your friends for if the person has some extra wire willing to sale it for cheap, I totally would do it, and I have done that before.
