Hey Guys,
Im trying to add in a MTX RE-Q (basically just a fancy line out converter) to my 2004 Nissan Maxima with Bose - but I can not for the life of me track down a proper wiring diagram anywhere.

There are two wiring harnesses/clips that go to the factory Bose amp, the larger one Im assuming is speaker inputs and outputs, while the other is just a power/ground/remote clip.

What Im looking for is what each wire is on the larger connector - I need to basically know what wires are the amplified speaker wires actually going to the speakers so that I can tap into those for the LOC (Front L/R, Rear L/R, and sub needed).

Any and all help is GREATLY appreciated!!!

This is for the bose system( at least what I am told)

Amplifier Output
Wire Function	Colour	Notes	Fuse #	Size	Location
12V DC Battery	Yellow		31	20 Amp	Fuse box at left front of engine compartment
Subwoofer amp also yellow, with fuse no. 18 of 15 Amps in fuse block behind left side of dash.
Remote Turn On (input)	GREEN / WHITE
Output for subwoofer amplifier on is also GREEN / WHITE.
Left Front Mid +	Blue/white
Left Front Mid -	Blue/black
Right Front Mid +	WHITE/ black
Right Front Mid -	GREEN/ black
Left Rear Mid +	GREEN/ YELLOW
Left Rear Mid -	Blue / YELLOW
Right Rear Mid +	Blue
Right Rear Mid -	Red
Subwoofer 1 +	White
These go to the left subwoofer speaker, and to the subwoofer amplifier inputs.
Subwoofer 1 -	Black
These go to the left subwoofer speaker, and to the subwoofer amplifier inputs.
Subwoofer 2 +	NCA
The right subwoofer speakers receive the signal from the subwoofer amplifier only.
Subwoofer 2 -	NCA

Thanks you VERY much - I haven't had a chance to check this yet on my car but as soon as I do I will report back here as to whether the colors line up.

Since you seem to be the only one anywhere that has access to the wiring diagrams for this car, would you be able to post the Amplifier Input as well - that way we can add this info to the "Vehicle Wiring" section of the12volt.

Thanks again!
