One member asked me how I did the install, so I figured I will post the instructions for everyone to see. The specific model number is Infinity Kappa 693.5i .
1) Measure and drill 4 holes for mounting of the new speakers. It is a little tricky because they have to be made with a relatively high precision. The new speakers fit tight into the opening. One of the tricks is to measure the first two holes, closest to the front, from the top, then approximate them and drill the holes from the bottom, from the inside of the trunk. The other 2 holes can be measured by installing the new speakers from the inside of the trunk, upside-down.
2) Because Infinity Kappas use large magnets and are overall bigger than the stock speakers, there is a fitment problem with the rods used in the trunk mechanism. The nice thing about Kappas is that they are made from plastic, a material that is easy to work with.
Figure out where the rods hit the speakers and "dremel-out " an opening in the speaker's plastic body.
3) Cut out a "gasket" to use between the new speakers and the rear deck. A 6mm foam sheet it needed. Put one of the new speakes upside-down on the foam piece and outline it using a marker. Cut around the outlined area. It is a good idea to leave an extra 3mm-5mm on the outside edge. Take a piece of carton, align it from the bottom of the rear deck to the speaker's location and outline it from the top. Cut out that piece and use it to outline the inside of the cut-out speaker-shaped foam sheet. Cut around the outlined area.
4) Install the "gaskets" on the speakers.
5) Install the screws that will be used to mount speakers into the speakers, puncturing holes in the "gasket".
6) Connect Cross-overs to the speakers.
7) Install the speakers.
8.) Secure the Crossovers. I taped them to the thick wire loom running behind the rear seat, right where the rear seat mounts.
9) Do the wiring, etc.
10) Enjoy your much better sounding system.
A few notes for the newbies:
a) Rear OEM speakers cannot be used with aftermarket AMP or Headunit.
b) OEM AMP cannot be used with aftermarket Headunit.
c) Aftermarket rear speakers cannot be used with OEM AMP.
