Q: so im lost in how i should wire my subs. I have two subs that i need to wire both are 2 ohms 400 watts i don't know if i should wire them parallel or series if you can help me out that would be great!: usually all sub wiring is the same, youll have the rca cables and antenna wire comming from the radio to the amp, power and ground wire going from amp to battery and ground, and than should have 2 wires coming off each sub to the amp, im guessing thatd be parallel, if you wire in series, so like use 2 wires and splice off to each sub, so 2 wires off the amp powering each sub you would up the ohms and put a too much of a load on the amp, people only wire in series when they have too many subs and not enough outlets on the amp, good luck

Q: I am looking for some answers when it comes to soldering wires. Lets say I am using 6 to10 (22 AWG 2 conductor wires) and I want to solder those to 1 wire for power source and 1 wire for ground. Now lets say soldering 10 wires to 1 wire for power and 10 wires to 1 wire for ground. All the wires are the same AWG guage. Now that the wires are twisted together and soldered to the hot and ground source, by doing this will I actually make a resistor or change the amperage or reduce the voltage by soldering so much wires together to a 1 wire source? The power source I am using is 12 Volts. If anyone knows of anywhere I can find this information online, etc, I would appreciate it.: The amount of wires won't create a resistance or change the current. The devices and the power consumption of each will affect current. How do you think a car fuse panel works? Many fuses (connections) all come from the same positive wire on the car battery. The battery provides well enough current for every device to be turned on (for a period of time) and no device will suffer from lack of current. ____________________________ Resistors are what limit the current to LEDs. The only way to exceed the wattage of a resistor is to short out the LED.

Q: 1994 crown vic but it seemed like only 3 or 4 wires matched up exactly and this one wire was way to short so i had to route it the best way i could the guy said it was the right set of wires but the car runs way better then it did just wondering should i change couple of wires around to make it fit or just leave it what does crossing the wires mean: Are the short wires touching any hot parts(exhaust manifolds)?If not, you'll be fine. There is a chance you used the wrong length wire for a few cylinders but as long as shes running fine and the wires don't touch hot parts you should be safe.Crossing the wires to me means running cyl 1 wire to cyl 5, this would cause your engine to misfire and idle really rough.

Q: to which wire in the back of my car radio do i hook my remote wire to from my amplifier?: Most factory radios, your Corolla included do not have a dedicated remote wire. Some will have a power antenna wire that can sometimes be used but the Corolla doesn't have a power antenna. You want to connect the amp remote to a switched 12V + source. The appropriate wire on your factory radio is the gray wire. That way, the amp will turn on whenever you turn on the ignition. Alternatively, you can connect the remote directly to any switched 12V wire.

Q: I need the wiring diagram for the factory radio of a 2008 ford explorer. i need to know which wires are for the back speakers so i can connect my Hi-Lo converter to it!? thanks: I believe this is what you are looking for, or should help... 2008 Ford Explorer Car Stereo Installation Instructions Car Radio Battery Constant 12v+ Wire: Blue/Red Car Radio Accessory Switched 12v+ Wire: Green/White Car Radio Ground Wire: Black/Blue Car Radio Illumination Wire: N/A Car Stereo Dimmer Wire: N/A Car Stereo Antenna Trigger Wire: N/A Car Stereo Amp Trigger Wire: Violet/Red Car Stereo Amplifier Location: N/A Car Audio Front Speakers Size: N/A Car Audio Front Speakers Location: N/A Left Front Speaker Positive Wire (+): White Left Front Speaker Negative Wire (-): White/Brown Right Front Speaker Positive Wire (+): White/Violet Right Front Speaker Negative Wire (-): White/Orange Car Audio Rear Speakers Size: N/A Car Audio Rear Speakers Location: N/A Left Rear Speaker Positive Wire (+): Brown/Green Left Rear Speaker Negative Wire (-): Brown/Yellow Right Rear Speaker Positive Wire (+): Brown/White Right Rear Speaker Negative Wire (-): Brown/Blue

Q: two straight and parallel wires are separated by 6 cm. there is a 2 A current flowing in the first wire. if the magnetic field strength is found to be zero between the two wires at a distance of 2.2 cm from the first wire, what is the magnitude and direction of the current in the second wire?: If the magnetic field at 2.2cm is zero it means that at that distance the fields produced by the two wires cancel out. At 2.2cm from the first wire the field strength is B= uI/ 2pi r ... . where u is the permitivity of free space, 4.0 x 10^-7 N/A^2 B= (4.0 x 10^-7 N/A^2)( 2 A)/ 2(3.14)(0.022m) B=( 8 x10^-7)/(0.138) B= 5.79 x 10^-6 Tesla The magnitude of the magnetic field from the other wire must be equal in magnitude at 3.8cm away (6- 2.2) and opposite in direction. Using the right hand rule (thumb points in direction of current and fingers curl around the wire to show the direction of the magnetic field) you can see that for the magnetic fields to be in opposite direction between the two wires the current must be flowing in the same direction as the first wire. Using the formula for magnetic field strength you can then determine the current needed. 5.79 x10^-6 T= (4.0 x 10^-7) I/ 2 (3.14)(0.038m) THen solve for I I= (5.79 x 10^-6 T)(2)(3.14)(0.038m)/ 4.0 x 10^-7) I= 3.45 A Therefore there is a current of 3.45A in the wire and it is flowing in the same direction as the first.

Q: sence my stock head unit has no remote wire, when I hook the amp up, will it still drain the battery? I have everything connected, but the deck does not have no remote wire, and if it does I have no idea how to locate it. I am worried it will continue to run the amp when the car is off and drain the battery. Am I worried for nothing? If it will continue to drain the battery, how do I prevent this from happening?: you just gotta make sure the wire you attach the remote wire to only has power when the car is on not when its off and you'll be fine

Q: currently I have 2 12woofers wired to a single amp with 2 gauge wiring. Will it make a noticable difference if I upgrade the wiring to 0 gauge?: Not.rly. if u have bigger wire yea it will have more power running thro it

Q: where also is fourth wire hooked in?: If it is coming from the box at the street into your circuit breaker panel, I'll take a guess. Earth ground (Usually connected to a copper water pipe or a metal pole driven deep into the ground) Neutral (0V) +120 V (Most household circuits) +220 V (Dryers, stoves, possibly air conditioners and other devices needing lots of power. These have special plugs.) Unless you are ABSOLUTELY sure you know what you are doing (and it sounds from your question like you may not be) DO NOT mess around with mains wiring in your house and especially wiring coming into your house, since that isn't even on a surge protector to keep you even remotely safe. If you mess around with this stuff without knowing what you are doing, you could wind up DEAD or in the hospital VERY easily. I can't stress enough how dangerous electricity in large quantities is.

Q: My home is wired for the thermostats with two wires (red and white). I have acquired a new thermostat that requires a Red, White, and Common wire. Using the white wire in that position will power the unit up but it won't trigger the heat. Is there something that can be put in line that will allow this thermostat to work without rewiring the house?: Connect a new piece of 3 wire to the existing 2 wire and pull it through the wall by pulling the 2 wire. Of course if it gets stuck you will need to measure how far you pulled to know where to cut a hole in the wall. Cutting a hole in the wall if needed, isn't a big deal you just put the piece back, screw or nail it down (cut so you have studs on both sides to reattach it later) tape and plaster and paint.
