I had my Infiniti Kappa 60.9 components installed front & rear.
 

So had my spears and amp installed. The speakers are running full range until box comes in. I must say they sound so good. People on the site were knocking the idea but I was given 2pr of components for less price a pair than 1 pair of Infinity 2-way drivers. So I took the deal and installed them and was backed up by another member that also put components front/rear in his 1st gen and enjoyed the sound/imaging. I'm just another member that agrees and isn't about just using front speakers with a sub because it leaves my rear pax with not good imaging. If you have any questions ask away.

Des,

These were how the rear doors were setup. Tweeters tilted up and towards rear passenger.
