I always use the black stripe as negative signal. Always do this and then when you have to disconnect something you won't get confused.(or as confused)
but honestly it's just wire it's up to you.
It actually does not matter as long as you are consistent. Most people choose to use the white stripe as positive, but it is definately not a rule.
Any marking (a white stripe, bump molded into the cable, different wire colours) is an indication for your reference only. It doesn't matter, as long as you connect the marked side on the amplifier to the same polarity on the speaker side.
It is Red with a black stripe
Red footwear was a sign of authority or status in ancient Rome. Julius Caesar would have worn red boots as a sign of his rank. Senators too, were allowed to wear red shoes (and a purple stripe on their togas) as a sign of their status.
Could mean almost anything. There's really no commonly accepted standard for color coding wire accepted in every industry and country. If you really need to know call the manufacturers hot line or read the owner manual....failing that you'll have to trace the circut itself.
For a 1998 Plymouth Voyager Minivan, the stereo wiring code typically follows these color codes: the left front speaker is usually white (positive) and white with a black stripe (negative), the right front speaker is gray (positive) and gray with a black stripe (negative), the left rear speaker is green (positive) and green with a black stripe (negative), and the right rear speaker is purple (positive) and purple with a black stripe (negative). Always double-check with a wiring diagram specific to your vehicle for accuracy.
The positive speaker wire is a solid color, your negative wire should have a stripe on it.
According to color code, it is the speaker negative wire.
The white stripe on clear speaker wire is usually the positive wire. You may also find it with dashes and this is still the one that will carry the positive charge.
For a 1989 Toyota Camry, the wiring color codes for the radio typically include: Yellow: Battery (+12V) Red: Ignition (+12V) Black: Ground White: Left front speaker positive White with a black stripe: Left front speaker negative Gray: Right front speaker positive Gray with a black stripe: Right front speaker negative Green: Left rear speaker positive Green with a black stripe: Left rear speaker negative Purple: Right rear speaker positive Purple with a black stripe: Right rear speaker negative Always verify with a specific wiring diagram for accuracy, as variations may exist.
Positive is normally red or white with a red stripe. Negative is usually green or on rare occasions black. A multimeter will verify this.
The speaker wire with a red stripe or marking is typically the positive wire.
Left Front Speaker Positive Wire (+): White/Red Left Front Speaker Negative Wire (-): Brown Right Front Speaker Positive Wire (+): Green Right Front Speaker Negative Wire (-): White/Orange
Black with white stripe = Positive. I tested this with a AC to DC wall plug. ________________________ It really doesn't matter if you connecting the wire yourself. As long as you define one as positive and the other as negative and keep that same definition throughout the system, it will work.
the preious answer is very wrong. some car makers have a stripe on both wires. the best way to tell is leave the factory speaker hooked up take a 9 volt battery with wires attached to it and slide one wire into each connection. if the speaker pushes you have the positive and negative correct with the markings on the battery if the speaker pulls in the they are reversed. The wire with the stripe is the "negative" wire.
It actually does not matter as long as you are consistent. Most people choose to use the white stripe as positive, but it is definately not a rule.
For the Panasonic CQ-DF583U car stereo, the typical wiring color codes are as follows: Yellow: Battery (constant power) Red: Ignition (switched power) Black: Ground White/White with Black stripe: Front left speaker (+/-) Gray/Gray with Black stripe: Front right speaker (+/-) Green/Green with Black stripe: Rear left speaker (+/-) Purple/Purple with Black stripe: Rear right speaker (+/-) Always double-check with the specific manual or wiring diagram for your model to ensure accuracy.
