Hi,

I'm slowly upgrading the stereo in my C2. I started with the easy stuff by changing the mid/low door speakers and the rear deck speakers. I'll probably upgrade the frequency crossovers and tweeters next.

Am I correct in assuming that the crossovers are screwed to the door panel from the inside of the door?
Is there a way of removing them without removing the door panelling?
Thanks, JW

Jeff Curtis

JW, the crossovers for the door speakers are located directly below the black plastic handle you use to open the door from the inside.

The door pockets provide a neat little compartment for the crossovers, they are actually screwed to the exterior of the door panel, again, inside a compartment between the enclosed door pocket and open door pocket.

You will have to remove your entire door pocket assembly to reach the crossover...overall, not a difficult job. Your door handle, etc. can remain intact.

Hoi JW,

Dit kan wel in het Nederlands, but for the benefit of Rennlist I'll continue in English.

Check out <a href="http://www.caraudioinnovations.com" target="_blank">www.caraudioinnovations.com</a> by Rod Birch. The site has many usefull tips for upgrading the stereo of your 911. Both system set-up and installation tips with many pictures. Rod Birch is a class act who helped me out with some queries over long distance.

Thanks for your reactions so far.

I've removed the door pockets a couple of times (just the lower half; I've left the map pocket lid attached to the door). I know where the crossovers are, but how do I get them out?

I had taken a long look at the caraudioinnovations site already, but it didn't give me a clue how to remove the crossovers. Mine seem to be screwed to the door from inside the door. I can see what looks like the sharp end of a screw in the mounting points at the top and at the bottom of the crossover.
Which leads me to think that I need to get a screwdriver on the other side of the panelling (inside the door), which means removing the panelling.
Or am I missing something simple here?

Thoughts, anybody?

The crossovers are behind the door handle structure, between it and the rest of the door. I have pulled them out and replaced my door speakers with a set of Pol Audio. It's got to be the easiest car speaker project I've ever done -- the panels really come off nicely - no need to be afraid. I guess you could just pull the door handle bar, map pocket stuff off without the whole panel, but It's really easiest to pull the panel and map pocket stuff off all at once, and take the whole thing in to a table to do your work on.

Yes, they are screwed to the door panel from the inside, which does make things a bit of a PITA.

That said, they can be removed with a bit of effort but prying the lower side of the door panel off, and reaching inside. We ended up breaking some of the plastic on the crossovers, but no biggy.

I had an installer do new speakers and head unit, and helped him wrestle them off. It would be 1000% easier if we took the whole door panel off, but it was cold that day, and starting to snow!

Best Regards,

JW,

Just curious. What did you exchange the standard speakers with. I have been browsing te web a bit, but until now did not find something that would fit. The standard stuff is not really worth anything, I'd say - and according to the option list I have a "HiFi Package"

I have a '91 with a Blaupunkt Stuttgart unit in it. For this set up, is the crossover a simple high pass filter for the low end cut off frequency of the tweeter, or is it actually an LC or LCR network?

Thanks,


Bill Wagner

Jeff Curtis

Actually Bill, both.

The crossover for the front door speakers has a low pass side, for the mid-woofer, of course...and a high pass side, obviously for the tweeter.

JW, like others have stated, the screws that hold the crossover are accessed from the rear of the door panel...I neglected to add the handy little tidbit to my original reply...sorry!

So, in summary, I think it would behoove you to go ahead and remove the door panel...it's likely you'll have to do a little trimming to the door panel only...the hole in the door itself is fairly large and for many manufacturers products, enable you to fit a 6.5" mid-woofer vice the original 5.25"...at least you shouldn't have to trim the steel!

I bought a set of Diamond Audio Motorsports, but only used the 5.25" mid-woofer because the basket on the mid-woofer was pretty large, had to trim the door panel for a 5.25"!!

As for the tweeters in the Diamond Audio kit, all I had to do is pop the factory tweeters out of their cups, lightly sand the hole to make it SLIGHTLY bigger and wallah! The Diamond Audio tweets pressed right in there. I put a bead of silicone on the back side to insure they stayed put.

A lot of people toss the factory amp in favor of another small style amp under the passenger seat. I used a Soundstream bass amp called an Angina and hooked it to an 8" bass tube.

My head unit is a high-end Pioneer, with 50W per channel, I know, I know, while NOT a true 50W RMS, it seems to cut the mustard, for now. So, the deck drives the Diamond Audio separates in the doors and a pair of Infinity Kappa 4" x 6" plates in the rear shelf...it's got a little "UMPH" to it, not bad.

I have another 2chl amp that I plan to hook up to the door speakers, as they will really "shine" when they have some quality wattage put to them...after all they are a fairly high-end setup.

It has taken awhile for me to decide where to put the amp, as it wouldn't fit correctly under the driver's seat and I didn't want to take up room in my ever so large luggage compartment!!

So, looks as if I've decided to mount it upside down, basically inside of the spare tire up front...but where do I put my compressor kit!??

Decisions, decisions. <img src="confused.gif" border="0">

Have at look at my audio section at <a href="http://www.stig.uklinux.net" target="_blank">www.stig.uklinux.net</a> it has a few hints n tips plus links to other good stuff

Hi,

The car is going to the shop today to have an alarm system fitted (and some miscellaneous stuff fixed), but I'll give the removal of the crossovers a go when I get it back. If the filters are anywhere near as good as the original speakers, removing them should improve the sound enormously

Can anybody give me some pointers on how to remove the door panels?

Cheers, JW

<strong>What did you exchange the standard speakers with. </strong>

I went for an el-cheapo solution. A friend of mine had two Philips speakers (don't know the type; they're 2-way 13cm coaxial speakers) lying around doing nothing, so I put those in. I don't like their sound characteristics, but they'll do for now. With a bit of bending of the mounting points, they fit in the original frame.
In the rear I used Kenwood KFC-4675; a no fuss replacement.

Tweeters are on the to-do list, but not very urgent.

The sound is far from impressive, but enough of an improvement that I can actually comprehend what people say during radio broadcasts. In the original configuration, traffic information was almost unintelligable.

Cheers, JW

This is all from memory, but it goes something like this:
To remove the panels:
start by unscrewing the philips head screws around the edges, put them in one place.....
You'll need a hex wrench -- 5mm I think? to remove the "cheese head" screwws in the following places:
two are at the door handle area -- this is by far the pita part of the project -- pull the handle open, and you can barely see the screws back there. At this time you'll see a little bazr that the door handle pulls to open the door, it has a ball/socket thing on the handle, pop it loose. You'll want needle noe pliers to hold the bar with, and use them again to pop the bar back in. Now you've got free access to the cheese heads. Take'em out.
Now the trim part on top op the panel has to go -- you'll find a little plastic cap at the end of the piece, pull it out, and take that little screw out. Also put it away safe.
The next cheese heads are at the end of the trim piece, on the door hinge side. Pull em out.

You'll also find that there's a plug or two on the long pull-handle, with cheeseheads under them.
Remove them.There's a srew at the end of the map pocket that holds the hinge block for the lid, off it goes.

After that , the memory gets weak, but a few more screws, and the whole panel will be willing to pop off.
Watch at this moment for the wire connectors that lead to the crossover -- disconnect them, and the panel is free.

You will find the crossover (mine was junk, as were the speakers) screwed on the panel (as I remember) under the front corner of the map pocket.

I replaced the set with some Polk Audios -- Crutchfield said they would fit, and they did, mostly, but the plastic surround for the big speaker needed trimming, as did a part of the box that held the crossovers, and I put duct tape around the tweeters to make then fit in the tweeter space.

Still a lot, lot easier than my Nissan Maxima

The below link is to "P-car.com" one of the best 993 sites around. The DIY pages include one on the door panel removal for a 993 with pictures (=1000 words)

I don't know if the 964 panel is way different, just hope this helps.

JW,

I went out today to have a look for the possibilities. I found that JBL makes sets that would fit the 964 - nice stuff too.

For the rear deck there's the P64 (4" by 6" @ 134 Euro a pair) and it seems that you would need the original cover to put on top of it. For the front a pair P52's (5.25" @ 134 Euro a pair) and a P-Kit (79 Euro) which includes 2 cross-overs and stuff to mount the tweeters. These tweeters are small, so they won't fit the original hole in doorpanel, but you could leave the original tweeters where they are. The cross-over should fit in the door pocket and leaving the original cross-over where it is.

The only thing I'm wondering now is how to get easy access to the incoming wires to the cross-over. You'd need these to connect to the JBL cross-over.

I also tried to remove the frames from the mid-low speakers, but these did not really give in - I'm afraid to break anything... The tweeter frame came of by screwing counter clockwise. Any ideas?
