Bose Wiring Diagrams!!
 

Here you are these are the outputs that go to the speakers. I am working on the signal diagrams now. What you can do with these diagrams is well a lot. You can install a JL clean sweep, tap into the sub wires for a MTX RE-Q for your sub, or use the speaker wire codes to cut them from the bose system and hook up a aftermarket crossover for your new speakers. "makes sure to disconnect the factory one that is in the door or before the wires enter the door" I am still working the rest out so please give me some time. Enjoy!:tup: I have not yet figured out what the L stands for what color so bare with me on that note as well.

This is the main harness that comes out of your bose amp. Also from what I have seen the wiring is exactly the same for the bose model with nav

Also anyone who has picks of the bose plugs and were they are located in the car that would help me a lot.

The stock wiring and all are coming. Also I was reading last night that some of you found a stock crossover in your doors. From the diagrams I am looking at there is not one, the wires go directly from the bose amp to the speaker. Now I could be wrong.

:wtf2::ugh2:

So...If i get a Clean Sweep could i install an amp and new speakers without removing the Bose Nav Head Unit and wire everything from the hatch?

You have to located your bose amp wherever that may be than tap into the wires that I put there. Well not tap into them cut them coming out of the amp and go into your clean sweep. Than run your new wires to your speakers off the amp. Also unless you are comfortable doing this stuff than I would have someone else do it.

Gotcha...but what do you do about or is there no fading of the front speakers? Does the head unit only limit the rear sub? lets say I wana replace all the speakers front and replace sub and amp would one cleanseep take care of all our problems (fading).

Each speaker output is it's own channel the fading all depends on what speakers are connected and all. The bose has channels just like any other amp or setup. So fading and all should be fine. The sub has it's own channel as well so that will have to be controlled by the MTX RE-Q.

i knew you cared about me.

I try to help people as much as I can. I hope that this helps them. Or at least until I work on one that has a bose system and learn more.

Bump

I was planning on a RE-Q5 till I can afford the HU I want with all the goodies, but still upgrade the sound. So what your saying is I have to cut the speaker output wires off the amp send them to the RE-Q5 inputs?

All the stock stuff has to go for the mids and tweet there is no upgrading the sub first then installing the next amp and new mids and tweets? Can you run the RE-Q5 for just the SUB leave the Mids and Tweets for now? Not worth the hastle?

Also the wiring diagram shows 4 outputs to the front, are all those full range from the Bose? Just pick say the two for the mid range front speaker and leave the front tweeter output out(cap the leads) when I switch out the factory speakers?

Just a few questions on a great old thread, spent a while looking for this.

So nice to get this wiring schematic, thanks Matt!

You can just disconnect the sub and run those wires to the brown wires of the mtx that would be fine. Only thing is unless you plan on keeping your head unit which your not you should just wait and save time and haste.

I was going to do the install in stages, complete the back half of the car, run just the power wire to the back for now.

Where abouts is the bose amp mounted? I think it's behind the drivers seat but not sure. I could mount everything under the sub location, all I need to do is build a false floor up with MDF and I can secure everything to that.

I think it is there. I have not done a bose system yet. Also make sure to run power wire for your mtx as well it requires power.

Can I tap off the Bose power supply? If not I am going to put the RE-Q5 with the amp anyway under the sub there is lots of power there I can run off my distribution block. All I need then is two wires off the sub channel for now, got a wicked sub upgrade for under $1000CAD dollars sweet!

You can do that but the wire for turning on and off the mtx needs to shut off so you can use the bose amp wire for that but the constant use a new one.

Front Right Door #5 - AND Front Left Door #5 - ???

using an LC2i which wire should i tap into, should i use the sub wires pre amp or post amp, or should i use a different speaker pre or post amp? I have never installed an LOC.

what are you trying to do? just add a sub?

You can grab the signal wires going into the harness of the bose sub, I believe they are purple and light blue, run them into a RCA end and plug directly into your new amp.
