I have an 03 with a Bose system and no navigation. I have searched just about every forum, and have came up with plenty of mixed answers. I just a bought a kenwood ddx 512 head unit and need some advice on the install. I want to keep the Bose speakers for now so what wiring harness do I need to connect the ddx512 to the Bose system?

 

Search for other threads on this subject, and check me on this, but I don't believe you can use the stock Bose speakers due to different OHM ratings, so they may not be compatible. I believe I read about this very subject - search......
Are they the original speakers? If so, they probably need replacing anyway...........

 

I also have an 03 with the Bose system. I just installed a Sony Xplod (crappy, I know) head unit cause my 6 disc changer went out. All I needed was the adapter to plug it in to the stock harness so I didnt have to cut the stock harness. Works fine for me...

 

What brand adapter did you use?

 

i believe you need one of the PAC-OEM's - forgot what the name is but i have one from an 03' bose no nav for sale if you want it - PM me - i can send you pics. Worked perfectly when pulled out of the car. Used it with a pioneer double-din and factory speakers

 

this guy is what you need:

 

How much?

Pac ROEM-NIS2. is what you need

 

Not sure what the brand was. It just has two female connectors that connect to the two plugs from the back of the factory head unit. Then, there are wires for each pin that you connect to the wires from the plug that goes in the back of your new head unit.
