So I'm looking for some photos of KAPPA PERFECT 5.1 and 6.1 installs. Specifically the 6.1s... How did you get them to fit??

Here's an install of Eclipse: http://www.windspear.com/jordan/S2000.htm . They helped, but still are far from sounding correct.

 

The 6.1s fit fine with an amply-hacked speaker basket:


But I ended up making a 3/4" MDF ring backed by a fiberglassed foam XTC baffle, which helps the fronts in bass reproduction:

 

What did you end up doing to the door panels?

 

Um, I put them back on...

 

Sorry, I should have been more concice. I take it you mounted the crossover on the door panel? And how much did you end up hacking the speaker mount that was there.

I'm concerned about decreasing the stiffness of the door panel and having it vibrate. It wasn't quite built for a set of "real" speakers and what they can drive.

 

Yep, the crossover is in the mysterious "black box" in the door panel. The speaker mount was basically entirely hacked away, leaving only a "ring" of plastic to mount the speaker to, which was then mounted to the door.

The plastic ring actually worked just fine. I too was worried about the door rattling, hence all the dynamat. But in retrospect it probably wasn't necessary, especially as I have the fronts crossed over relatively high (~100hz).

 

what is a fiberglassed foam XTC baffle.
My understanding was that a baffle was the component that your speaker is mounted to, ie, the MDF ring.

I also wouldnt worry too much about vibration, its not like the S2K is a quiet cabin to begin with.

 

I guess "basket" is a better word than baffle. It's a piece of foam that is treated with fiberglass resin for stiffness, which effectively seals off the airspace behind the speaker. This protects the speaker, and helps somewhat with bass output. It also helps keep the side mirrors from shaking too much.

 

shaking side mirrors is a problem
where did you get those? Creating something of an enclosure is a DEFINATE plus.
