Re: Installing 4 after market speakers in my Ford F-350....
This is actually a quotation from a site on the net as i've wondered about it to
"Speaker wire has a mark or strip on one of the conductors this is to indicate polarity of the wire. When installing speakers to the output of an amplifier you need to observe the proper polarity. This is particularly important when installing a surround sound system with front and rear speakers. If the polarity is not followed then the results will be poor balance of sound and even cancellation of some frequencies."
a 6ya expert can help you resolve that issue over the phone in a minute or two.

OK,GMC/GM are wired as such. White/Black wire, front left -[neg] White, front left +[pos]. Grey/Black wire, front rt -[neg], Grey wire, front rt +[pos]....Green/Black wire, left rear [neg], Green, left rear [pos]....Violet/,Black , Rt rear [neg],...Violet, Rt.rear [pos]........You will also have a Blue/Red wire that goes to antenna. ..A Blue wire for Power Remote....Red goes to IGNITION.....Yellow goes to Battery[for clock].....And finally a Black goes to Ground.......I hope that you have good luck and everything works out for you. `
Something has been mis-wired. Ensure the speakers are in the speaker slots and the power (Neg and Pos labeled as well) are properly connected. It is fairly common to get the speaker pos and neg mixed up with the power pos and neg. Hopefully, no permanent damage was done. The problem is between your factory radio and the aftermarket power amp.
RED IS USUALLY POSITIVE RED-WHITE IS MORE THAN LIKELY NEGATIVE TO CHECK SPEAKER POLARITY: 1. HOOK LEADS UP AS I DESCRIBED 2.TAKE A AAA,AA,C,OR D BATTERY 3.CONNECT POSITIVE SIDE TO POS ON BATTERY...NEGATIVE TO NEG END...... 4. IF SPEAKER "CONE" PUFFS OUTWARD..POLARITY IS CORRECT. IF IT PULLS INWARD..POLARITY IS REVERSED
Hello, I am assuming it is the rear passenger speaker. Please refer to the list below for the wiring of your aftermarket speaker.
Radio Constant 12v+ Wire: Orange Radio Switched 12v+ Wire: Dark Green Radio Ground Wire: Black Radio Illumination Wire: Gray Stereo Dimmer Wire: Violet/White Left Front Speaker Positive Wire (+): Tan Left Front Speaker Negative Wire (-): Gray Right Front Speaker Positive Wire (+): Light Green Right Front Speaker Negative Wire (-): Dark Green 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
your right front speaker neg side is Green with a orange stripe
your right front pos side is Light tan with a green stripe
your left front neg side is a light blue with a white stripe
and the left front pos is orange with a green stripe,,
a typical new radio will have a gray with a black stripe for the neg side and solid gray for the positive, on the right side
and the left will have a white with a black stripe for the neg, and solid white for the positive, if you need anything else just reply to this feed and I'll help you
pink = (+) pos. for left front speaker violet = (-) neg for left front speaker light green = (+) pos. for right front speaker blue = (-) neg for right front speaker blue/yellow = (+) pos at all times (power) grey = (+) pos. only in the accessory or run position brown = (-) neg gound red = (+) pos. right rear speaker black = (+) pos. left rear speaker white = (-) neg right rear speaker yellow = (-) neg left rear speaker
work it out with a meter ,,,,find perm 12v feed neg and pos ---yes could be any coloured wire depending on car maker,after finding perm 12v feed for memory look for pos from ign switch,now speaker wires are easy as both will be same colour for a speaker but one will have a band through it if not sure or colour blind like yours truelly then use pos and neg on speaker wire till you hear a thump from speaker then you know you have the right wires and location of speaker ,,ie.. front left back right ect ....Now you are a fully experianced radio fitter ??
