I pull the wires out from the speaker. I want to return them in place but I don?t know witch one goes to were. One wire is brass colour, the other is more red colour. Cam any one helps with this?

red wire is live (battery) yellow wire live only when ignition is on, black wire is earth(car body) there should also be 4 pairs of wires green,white,grey and purple these are your speaker wires you'l notice with the pairs of same colour eg white one is solid colour one has a black stripe the solid colour goes to live + on your speaker the one with stripe goes to - on speaker, same goes for the rest of the pairs hope this helps

Could you specify the model of the Sanyo speakers?

As far as i know the "RED" wire is usually the Positive + wire on those cars

But if you really want to be 100% sure you can do this little test..

(This is assuming that you are removing the stock speaker and replacing it with a better one? )

Anyway just look at the old speaker with the wires plugged into it like it was before and make a note of witch wire goes to what connector on the speaker
Then disconnect the wires and touch the two terminals on the speaker with a 9volt battery and if the polarity on the battery is correct on the speaker it will move outward and if it is reversed then it will move inward... that is a good way to determine the polarity of the speaker itself then you can look to see witch wire goes to what connector on the speaker and that should tell you which wire the positive one is

Hope this info helps

if you mean which wire to put to earth so you can watch dvd's while u drive its the light green one

dnt get confused, follow these simple wiring .......
firstly cut off the old lug from the connected place, make sure you cut each wire seperatly....and you are going ti use the wiring agin, avoid making the wires shorter...
YELLOW..12V+ DIRECT FROM BATTERY...can be joined where alpine yellow was conected.
RED...12V+ IGNITION WIRE..can be joined where alpine red was connected
BLACK 12-, NEGATIVE....BODY GROUNDING
ALL SPEAKER WIRES HAVE +AND-, PURPLE/PURPLE----------WHITE /WHITE-------GREEN/GREEN.......GRAY/GRAY..ALL THESE ARE SPEAKER WIRES, COMPARE THE CONNECTION OF ALPINE AND FOLLOW THE COLOUR FROM APLINE LUG AND JOIN THE PIONEER LUG ....THEY HAVE BAISC COLOUR WIRE AND AHVE SAME TYPE CONNECTION..DO IT

hook a single speaker to 1 contact doesnt mater witch wire is witch
gat a tone generated mp3 from internet burn to cd
put cd in turn it up and look to see what way the speaker moves
once you figure that out remember a speaker should deflect outward not inward hook wires accordingly 1 by 1 and you are done
place hand on speaker b4 your friend turns up the radio each time and you can feel the speaker away or push up on you
remember to mark your wires for future
i like the addage this is not negitive.. so tie a knot in the positive wire

The easiest way is to check the speakers themselves as manufacturers tend to change colors of speakers at a whim. Usualy though you will have 8 wires (4 front & 4 rear) paired in colours (white goes with white+black stripe(stripe is possative on speaker))etc.
Not knowing the cars electrics I can't be more specific.(I live in UK so don't know that much about U.S. cars)

the best way to find out which wire is which is grab a test light now find the BATTERY WIRE and IGNITION WIRE the battery wire should constantly have power and the ignition wire should only power up when u turn the ignition on

the other wires are ur speaker wires what u would need to do is get a AA battery snip the wires that have the same colour but one should have a striped colour with it and make the wires touch both ends of the AA battery u will hear a speaker make static sound this will determine which speaker that wire goes to

Let me know how u go

BTW the earth wire just goes to the body and u will have a Interior light wire wire that to the cigerette lighter globe

Here's the best thing you can do:

Cheers!

use a test light with ignition off when u find power connect it to yellow(memory) then on acc when u find power conect red connect black to earth blue is optional (power antenna) find the speaker wires colors at the back of each speaker and connect the two of the same color to each speaker striped wire + no stripe - hope this helps
