I recently had a chance to install some infinity reference separates:

in the front doors of my 2001 JBL equipped SR5 Sequoia, using mjmaudioinnovations adapters:

The installation took about an hour and everything lined up great.
I did in fact install the tweeter along with the woofer. I tried to keep as much of the original harness as possible. I used a small female solderless connector on the negative terminal of the woofers (re used the original female connector on the positive terminal.)
I used solderless butt splices on the tweeters because they had leads already soldered on from the factory.
In my opinion it sounds great and the adapters were perfect.
