So I’m thinking of getting all new door speakers and I would like to know it I need a wire harness and the speaker brackets? I also have the Bose system



Does anyone know the mounting depth? I searched and couldn’t find anything.

The door speakers are 6.5. You will need some mounting brackets. Mounting depth is not going to be an issue, unless you are putting something like a sub in the doors. You will have issues running aftermarket speakers with the Bose headunit and amp, since the factory Bose stuff is 1 ohm. My suggestion is to bypass the amp and put in a new head unit.

1 ohm? What's your info source?

It is. My source is a DMM. Almost all Bose stuff is 1 ohm. You can take two dvc 4ohm speakers to 1 or 1 dvc 2ohm to 1ohm(which you probably can't find in the 6.5 size. If your not replacing the amp find the highest sensitivity speaker you can that fits your needs. If you double the resistance (ohms) you half the power the amp put's out. Most 6.5's are going to be 4 or 8 ohm. So if the amp put's it 150w at 1ohm, at 2ohm it's 75w, and at 4ohm it's 37.5w. that's not enough to properly drive most aftermarket 6.5's during heavy listening. Don't forget that amp also drives the rear door speakers.

Interesting. I've never ohmed out a stocker speaker. Always just assumed 4 or 8ohm for cheaper production. 1ohm voice coils are not a standard production rating for any speaker/application.

Yeah, it's a Bose thing. I think they found it cheaper to build an amp that can make more power at 1 ohm than use highly efficient speakers. They are the best at what they do so I'm sure there's some clever reason.
