Infinity Kappa dashtop upgrade

[Gary H]

Time: 1hr, complexity: Simple. Basic tools required: Hex socket, strong pliers, silicone sealant, small Philips screwdriver, cable stripper.

After doing some research I decided on the Infinity Kappa 42.9i co-ax speakers as the replacements for my dash-top speakers. I won't go into the reasons in depth - but they're on the Infinity website, but the main reasons were these speakers are almost designed for the modest upgrade (I'm planning 50watts RMS per channel) and are very efficient too. I'm not going for hi-fi, nor am I going for street bass, but 93dB/Watt is impressive.

Anyway, the procedure is fairly straightforward. There are plenty of guides on the web, but this is how I did it:

1) remove hex-screws with a tip. These should be hand-tight only.



2) Use a small screw driver to push the edge of the connector in to remove the socket. Curiously , this has a VW/Audi logo on it (!)



3) You may have a tweeter installed. Just snip the wires near the tweeter and leave it in situ, we won't be using it.



4) Thank your little helper, but tell him politely but firmly his help isn't needed



5) Don't let the fact that the paper coned original looks bigger...



6) Flip them over to see the obvious difference.

7) We only require the mounting ring from the original , so cut all the way round...



8) and then seprate by cutting out the cone by the rubber ring surround



9) What you're left with looks simple, but is invaluable for a quick and easy fix:



10) you will need to cut the lugs down, approx half-way and go for a trial fitting. It's better to have a tight fit than a loose one - as the four lugs will be the securing points on to the mounting ring



11) Once your happy with the fit, hot glue/silicone the bottoms of the lugs, and pull up the mounting ring. Once the glue has gone off/set, use the foam supplied with the speakers to seal the edge the whole way round



12) I decided to get rid of as much of the dirty, dusty crumbly foam from the inside of the grill as I could:






13) Finally, re-assemble the speaker with the now attached mounting ring back onto the grill housing using the three screws that you removed to take off the speaker.

The Kappas have a lead with a +ive and -ive junction box so rather than try and re-use the old connector, I simply cut off the connector, bared back the wires and screwed them in to the junction box. IIRC Yellow and Yellow/brown and red and red/brown were the speaker wire colours, the brown stripe indicating negative.

Before remounting the speakers, I managed to stuff approx 12" square of acoustic wadding down the cavity.

14) AS a final touch, I prised off the infinity badges from the original grills and managed to get them glued to the car's.

Great post Gary, one more for my "to do list"

Nice work!

What did you use to cut up the outside mounting locations on the Kappas?
