ok, i have been putting a new stereo into my 3. ive got 6.5" rainbow comps going into the doors. my only question is about accessing the door jam to get the wires through. i went as far as ripping out the glove box on the passenger side to look for access, but still couldnt find it. has anyone ran wires to the front door speakers? any help is appreciated. thanks.

 

I couldn't find a way either, but I didn't try to hard. Put your crossovers in the door and you can use the factory wire to get signal to the crossovers. I get get into more detail if you need me to, but if you bought rainbows and are installing them yourself, I trust you know what Im talking about.
