TOOK OUT THE FACTORY BOSE HEAD UNIT AND AMP. WILL REPLACE WITH AFTERMARKET PARTS.NEED TO KNOW THE COLOR CODE FOR THE 10 SPEAKERS IN MY TRUCK? THERE WERE ALOT OF WIRES ON THE BOSE AMP AND I REALLY DON'T WANT TO TAKE ANYMORE OF MY INTERIOR APART TRYING TO TRACE WIRES. ANY HELP WOULD BE VERY APPRECIATED

Are you planning on using the bose speakers with an aftermarket amplifier?  Or did you just want to use the existing speaker wiring?

just so you know, you can't use the bose speakers with aftermarket amplifiers because they're 1 or 2 ohms and most amplifiers can only handle 4 ohm speakers.

Was planning to use the same speakers for the present time. Will replace speakers at a later date. Will purchase an amp that will handle a 2 ohm load and if i have to i'll try a series parallel wiring for the speakers to get the ohms around 4. Sounds like it might work. What do you think?

the bose speakers are probably 1 ohm, which means the only way to hook up to an aftermarket 4-channel amp would be to hook up two bose speakers in series, and then run the single load off one amplifier channel (2-ohm stereo load).  I'm sure there aren't 10 full range speakers in the vehicle, so you can probably get away with hooked up some of the tweeters in parallel.

The easiest way to figure out which wire goes to which speaker, would be to use a speaker popper.  Basically just a 1.5v or 9v battery with a wire hooked up to the positive and to the negative terminals.  Then you put the positive on one of the speaker's leads, and the negative on the speaker's other lead, and you'll hear one of the speakers make a popping noise.  Then for polarity use a multimeter to measure voltage across the two speaker leads on the amplifier side, while the radio is turned on.  Positive voltage means the wire touching the red test lead is the positive speaker wire, and negative voltage means the wire touching the black test lead is the positive speaker wire.

Just make sure you do the speaker popping on the side of theharness that is coming OUT from the amp, so that you don't send voltage into the amplifier cuz that could damage it.

And remember, if you don't get creative with the speaker wiring and instead just hook it all up to aftermarket components as if the bose speakers were normal speakers, you will more than likely fry your aftermarket amplifiers.

Already removed radio and amp but, I guess i can put it back in because i didn't cut any of the plugs yet. Before i do this is there any way to check speaker polarity without using a volt meter because once i stick the plug with about 20 or so pins i won't be able to access the wires to test them. Cut the insulation on each wire maybe? And bye the way thanks for your help.

There is a way to do it without using a Volt meter , using a 1.5 Volt Battery To Test It. Heres what you do,take the speaker wires in question put one on the + side of the battery and put the other on the - side now watch the speaker if the speaker moved out than whichever wire is on the + side of the battery is positive on the speaker,if the speaker moved in than the wire on the positive side is - on the speaker..

hope this helps
