Thread: Fitting 6.5 Kappa's in '94 B13 Sentra SE-R Doors?

So tried to install the Infinity Kappa's into the '94 SE-R with not much luck. Modded the metal plate that came with the speaks to match the three bolts of the original 4x6 mounting plate. But, with the speaker mounted and wearing it's plastic protective shield, the inner door panel won't close all the way!

What do I do?

Looks like the part of the inner door panel that goes concave for the door handle is hitting the top portion of the protective plastic ring of the speaks. I'm in a quandry. How are you peeps getting these larger speakers to fit without extensive modding?

Well in mine I used polk db6501 I think. I found out that you couldn't use the plastic adapter otherwise I didn't have enough clearance to put the door panel back on. What I had to do was drill new holes for that speaker, but I still used the thin piece of foam that came with the speakers so there wasn't any metal on metal contact.

If you are trying to get a better quality sound and you have sub(s) or speakers in the rear better at handling bass a set of bass blockers are a good cheap investment for the fronts. I got some and I think it made a huge difference of the overall sound.

X2. Put some sound deadening around the speaker hole and carefully drill new holes for you new speaker. Always measure 3 or 4 times and drill once.

I just pick up a set of Kappas and was planning installing them this weekend....from reading the post above it looks like its gonna be a fun.

The stock drivers side speaker looked like a 6.5" speaker with an oval cone...is this how the stock speakers look?

Yep, they're round metal discs with 4x6 speaks floating in them. Rather odd, actually.

Okay, here's what I did.

1) Remove the screws along the sides and bottom of the door panel and the two behind the door handle-pull, not the two screws holding the handle parts together.

2) Pull the window crank out a bit and using needle-nosed pliers, grab the metal wire and pull out the clip. The window crank slides right off.

3) Pry the bottom of the door panel out. No need to remove the whole thing. I used a slightly deflated football to prop open the panel.

4) Using a short phillips screwdriver, pull out the three screws holding in OEM speaker.

5) Snip the speaker wires as close to the speaker plug as possible.

6) Connect the speaker wires to the input wires of the Kappa's crossover. The striped wire to the black Kappa wire. The un-striped wire to the red Kappa wire.

7) Attach the connectors on the other end of the crossover.

8) Weatherproof the crossover. This will be wedged inside the door. So, it makes sense. I encased it in a zip-lock bag and used twist-ties and electrical tape to seal it all up.

9) Then enlarge one of the speaker mounting holes on the lip of the Kappa. I used ovalish needle-nosed pliers. (Stuck them in the hole and twisted to stretch it out a bit.)

10) Stuff the crossover and excess wire into the door through the hole at the bottom of the speaker baffle.

11) Thread one of the three OEM mounting screws through the enlarged mounting hole and line it up with the top mounting hole in the door, screw that baby in!

12) The other two screws do not line up with any of the remaining three holes, so I used them to pin down the perimeter of the speaker. It's appears to be very secure.

13) Crank tunes!
