Q: What is the best brand of wire to use for getting power to my amp?
Monster cable 10 awg
Q: I need a wiring diagram for a 1983 honda rebel, its a 250cc parallel twin, i really need the ignition wiring diagram but i can't seem to find one. If anyone knows the letters (xx250,xx125) then that would help to. Thank you in advance.

Q: Car audio wiring diagram
If you cannot get a wiring diagram for your stereo or car. It's still pretty simple to install a stereo. You basically just gotta color code all the wires. Red sometimes orange is power wire, black is ground, blue is remote the rest are speaker wires. Look for wires that are identical such as light blue light blue with a white stripe, gray dark gray with a white stripe etc.....
Q: how are lights grounded on a car? Seems like all the wires to the light have electricity running to them.
a ground runs from light assembly to the body of the car (unit body cars)usually just trace the wires if you can or look up a wiring schematic on the internet for your car that's the best thing to do actually or buy a manual with the electrical diagrams good luck
Q: i need to know which wire is which in a 1999 dodge stratus for the cars stereo

Q: What are the advantages and disadvantages of a bank wire transfer ?
A wire is a paperless transaction between banks. The electronic submission of money debits your account (payor) and pays the payee. I put money in quotes because there is no physical dollar bill that changes hands. It subtracts the amount from your account and adds it on to the other account you're paying. There is a trail for such a transaction, so it can be traced from one bank to another. It is instantaneous, like a debit card transaction, in that the payor's account automatically has the funds taken out of the account (held for close of business when the bank feeds all the wires through) and the entity receiving the funds has them the next day. advantage: It's instant (if you're buying a car in full w/ a wire, the car is fully paid in 24 hrs. A check of that size may have a 10 day hold on your account before verifying!) Disadvantage: it costs more than a check. Wires are a few bucks to about 20 bucks. Not practical on smaller transactions, but if you forgot to pay your daughter's tuition and she's about to start class, this scenario is perfect.
Q: A potential difference of 13 V is found to produce a current of 0.37 A in a 3.1 m length of wire with a uniform radius of 0.42 cm.(a) What is the resistance of the wire? (b) What is the resistivity of the wire? Please show work.
Voltage (Volts) = Current (Amps) times Resistance (Ohms) or V=IxR = R = V/I = 13/0.37 = 35.14 Ohms Resistance = Resistivity * Length/Area The longer the wire is, the more resistance it has. The larger the crossectional area of the wire (pi times radius^2), the less resistance it has Longer wires have more resistance, thicker wires have less 35.14 = Resistivity * 3.1/pi*0.0042^2 Resistivity = 35.14*pi*0.0042^2/3.1 = 6.281 x 10^-4
Q: And if anyone could give me percise instructions on wiring subs to 1 or 4 ohm that would be great. I have two dual 4 ohm subs and need to know how to solder wires or crimp wires.

Q: Does anyone know what color the amp sensor wire is on a 2005 EX?
DIRECTWIRE? WIRING INFORMATION - KIA / SORENTO / 2005 / Audio Radio 12v green + Radio Groundblack - Radio Ignition green/orange + Radio Illumination red/black + Factory Amp Turn-on Power Antenna N/A LF Speaker +/-brown - black +,- radio harness or amp under driv seat RF Speaker +/- green/orange - blue/orange +,- radio harness or amp under driv seat LR Speaker +/- green - blue +,- radio harness or amp under driv seat RR Speaker +/- blue - yellow +,- radio harness or amp under driv seat Sorry this doesn't list the Amp turn on wire, but now you know a buch of wires that it is not!! Good luck...if you test with a voltmeter, the amp turn on wire should not have 12v in any key position. MikeC
Q: i have an amp (sony xm 2002gtr) that says it requires 4 gauge wire..but they cost $100+ and i have plenty of 8 gauge wires. can i use two 8 gauge wires as a substitute for one 4 gauge wire?and also, i have my capacitor grounded to unpainted metal of my car AND the ground port of my amp..is that incorrect?
Two 8-gauge wires combined are equal to a 5-gauge wire, but that should be close enough for that amp. Make sure each wire has its own fuse near the battery; 40-amp fuses would be a good choice. If you capacitor is connected to ground, and your amp is grounded, then you don't really need a wire between the capacitor's ground terminal and the amp's ground terminal. It doesn't hurt anything, though. If the only ground wire at the amp is the one that runs to the capacitor, then you're better off connecting the amp ground directly to chassis metal.
