I would love to replace it at a later time, my biggest concern at the moment is just the power drain. It's really frustrating not knowing if your car is going to startup, or having to flag someone down for jump starts...

Can anyone enlighten me on which wire harness it is? I'll try and post up a photo later today. Blue (24 pins) and a smaller white harness (6 pins).

Thanks all for the advice!

Pull first harness. If yellow w/red stripe isn't there, it's the other one.

Where is the Mute wire for BOSE 03 6MT??? Trying to install a Blinder M47 Laser Jammer and gotta know where mute wire for audio is and a good solid switched 12 volt is. Any help?

There isn't a mute wire. If you get creative with relays, you can create your own, but I'm not feeling up making up a wiring diagram.

Switched 12 volt - use the cigarette lighter power wire. Easy to get to, and can supply a fair amount of power.

This is a great thread, thanks for posting the diagram... I'm a little confused, and hopefully I can get an answer to my question/s... haha...

OK, I have an 03 sedan and I want to add a 4 channel amp in place of the Bose amp and keep my stock Bose stereo...

I will be using a hi-to-low converter(or LOC)... My question is, what wire/s do I tap into so I can use the LOC?

Also, from my understanding, the wires with the sleeves around them are the wires that go directly to the speakers?

Thanks in advance for any help!

i have a aftermarket hu, and my sub isnt working. On my hu, it has rca plug in slots for the sub, so would i have to run a pair of rca cables form my hu to my sub? (since the sub has its own amp) I have the metra harness installed that has the rca cables, cuz my old stereo had the dreaded radio problem. Everything thing audio wise is stock except the hu.

From my original post
"The wires coming from the HU have a sleeve around them (in pic) and ones leaving the amp do not."

You want to amplify the wires that have not gone through the Bose amp so you want to use the wires with the sleeve.

I'm not going to use the Bose amp at all... I'm going to unplug it and basically have the harness by itself... I just want to get a signal from the headunit(For th LOC) and find the actual speaker wires to run those to my 4 channel... But I think I got it figured out already...

The bose headunit outputs aren't speaker level outputs, so a LOC won't do you any good, they're already line out. Additionally, those signals are differential-balanced, so a LOC won't do any good again, since it doesn't convert the signal to unbalanced.

Read this post for a great explanation:

OK, So I just finished the install and it went just as I thought... I will write what I did below, just incase it will help anyone else wanting to do what I did... And yes I did use an LOC...

I disconnected the Bose amp,(trashed it) and left the harness hanging... I tapped into wire #9 on the harness for my remote turn on... I tapped into #19 and #6(which have a grey sleeve around the two wires) for the input on the LOC... on the LOC, twist both of the + wires together and then twist both of the - wires together... Connect the + wires to #19 and the - wires to #6... and now plug in your RCAs to the LOC...

Now, tap into wires # 12,13, 14,15(which are the front speakers) and run the wires directly to the amps front outputs...

Do the same for wires #1,2,25,26(which are the rear speakers) and run those to the amps rear outputs

You might need to use y-cables on the input side of the RCAs if your amp cant send the signal to the rear channels through the front like my amp can...

I'm running a Boston GT-40 4 channel and my JL components and coaxs are going in the door 2moro...

BTW, I did lose the ability to run my OEM "woofer", but I don't need it and now I will be motivated to remove it!

Remote:9
Input:19/6
Fronts:12/13-14/15
Rears: 1/2-25/26

Pretty much every speaker ever is better than Bose.
