Chad,
I don't recall the wire colors and all I can do is refer to the pics (as you are already doing).
From the pics, it looks like the black striped wire went to tweeter black (assumed neg).
It did not seem possible to insert it differently.

Sorry, but I have not had my door panels off, to get any DC Resistance measurements on door woofers or mids.
I had been thinking of changing them, but I'm now holding-off on any further changes, until I can decide on what makes the most sense.
Kind of thinking of adding a HPF on the door woofers and a LPF on the mids, to clean them up.

For you experienced car stereo installers,
I wonder if stuffing the dash cavity will help the Burmester Sub?
If so, what material would work best?

Sorry- I meant the door mid/woofer ohms....or is that what you meant?

Looks like I totally missed what you meant.
I edited my post, since you were not asking about the Sub Woofers.

is the consensus now that the burmester tweeter should have a high pass filter connected?
Are the people that have done this mod having any problems with the burmester tweeter without a high pass filter?

thanks

I've not noticed any problems. What sort of problems would likely manifest?

Yes, and clipping at higher volumes and at more bass-y frequency inputs.

I'd highly suggest one... Without the filter, a loudspeaker driver such as a tweeter can be overdriven which can lead to distortion and eventual failure. Think of a tweeter trying to produce bass frequencies. It can’t do so efficiently (or mechanically!) so we employ a HPF to block those frequencies... This is a cheap fix and protection for this mod. You can even buy the male & female connectors to make an adapter so no cutting of factory wires would be involved.

Slight side-track: is there any forum where people discuss sound quality of car stereo components in detail?

I could find some car hifi forums but they are mostly concerned with getting their bluetooth to work and getting flashy head units.

I didn't find anything like this thread. Sound quality. Speakers. This thread is awesome but the 991 focus limits the audience.

Anyway, keep up the good work. Feel free to pm instead of followup if you think it's derailing.

So my tweeters are finally arriving Monday after a month long wait. Btw the cost seems to have increased as it was $430 shipped for the speakers, grills and hardware.

Now the question is what to do about these bass blockers. No one thus far has reported a single issue after installation. If these little tweeters can reproduce some of the mids and that's what makes them sound so good compared to the Bose perhaps using a different bass blocker of maybe 0-500hz would be better than blocking everything below 5.6khz or 2.8khz that the tweeter specific bass blockers do.

What ohm do these speakers run?

Not sure if I want to just run them bare or get the bass blockers...no failures to date and could cut down on speaker range for added unnecessary protection. Hmmm...

So far so good, been couple weeks and sound is improved. Might be that I don't listen as loud as others

I have made a wiring harness to bridge the bose connector to the burmester
and soldered a 8 mfd capacitor within the harness

testing it out in the car, demonstrates that it acts as a high pass filter. ( i hooked up a full range speaker to the wiring harness and no low frequencies were audible)

For the speed nuts, is it totally necessary to trim them down to fit? Someone had posted a pic of them cut down below.

I know some guys got other fasteners, but I'd like to use the OEM's. Also, 6 come in a pack. Need all of them?

Thanks


One that was posted which was trimmed on the sides
