No way for aftermarket Head Unit with BOSE System

So im extremely frustrated now. I was so amped to finally have ipod integration and full control of my system. I had a kenwood head unit that i would be using for this project. So i ordered the single din and the wiring harness for the 02 c230 coupe. I opened up everything and shocker only one of the harnesses coming out of the car fits, and the pins dont even line up. So i mustve ordered the wrong wiring harness...WRONG. I ordered the Metra part 70-941 which was told to me by some forumers that it would fit the car and they personally use it themselves. Funny, the metra part had the same exact pin line up and again it did not fit the car. I called the tech support and they tell me if i have Bose system then the only way to put an aftermarket HU is to bypass the amp. I would do it myself but im sure its extremely complicated. SO this is my last try. IS THERE ANY WAY TO FIT AN AFTERMARKET HU IN MY CAR?

What you end up doing is running speaker wires to the amp to bypass it or rewiring the speakers throughout the car. It is also recommended to change the speakers out as well. GL

First of all, do you have a Bose system?

Do you have the Bose emblems on your speakers?

It has something regardless... If you see in the picture posted there are no speaker wires as one harness is empty

Jerry,

Maybe Im not seeing this right, but the car harness that he has plugged into the HU harness (bottom plastic piece in pic) has 4 wires (green/black, red, yellow/black, black) and 1 brown (ground) for the 4 speakers.

Again...I could be wrong...but if this is just a different layout for speaker wire arrangement, he should be able to make it work with some jerry rigging.

no those wires are for something else I wouldn't mess with those typically in all european cars speaker wires are twisted pairs... and if i remember correctly that other plug (the one not plugged in) will not fit on the harness..

if you see here (pic below stolen from javvys thread) the tan harness are speaker wires usually a twisted bundle with matching colors for -.+ leads..



but no worries I gave him all the info he need in the coupe forum
