Hello Everyone , I need the pin layout for bose amp harness . I searched but I found a few types not sure what works for my car . its a 2004 clk pre face lift. Thanks in advance...

 

If you are tapping into the analog speaker wiring there, then the colors are the same as they for the radio wiring harness:

No i will be tapping into the harness that goes from the amp to the speakers .

 

This is what I found them to be when I swapped everything in my car:

Orange=front right
Baby blue/off white=rear right
Green=front left
Pink=rear left
Blue= center
Purple=sub

+ Pos is Striped

 

how about the tweeters ? are there wires from the amp to the tweeters or is the wiring in the door ?

 

Tweeters and woofers are tied together on each channel and are not driven independently. There's a filter for the tweeter to operate properly. Although I'm certain they exist, I have yet to see a factory system set up with dedicated channels- each one I have seen used a basic filter or crossover. Would be nice if they did though! I'm assuming if you're adding an amp that you're also swapping speakers? The Bose speakers are very low quality and are at extremely odd impedance's.

 

Yes I am replacing the front speaker with components . 2 way for the rear speakers and I found a small sub that I am trying to fit in the original Bose box . Thank you for the help I will update with a diy
