I don't know if it will help, but yes, I would definitely try a lower attenuation setting and see if that helps at all...

 

Good luck,

Mark

Checked the xovers today. All at lowest setting of -6db. I checked with the other settings, and -6b is the lowest.. .with 0db the highest.

My problem is that the high frequency/tweets are like sandblasting my eardrums! Like really raspy at times... and not at ridiculous volumes or anything.

 

Well, like a couple other people said the D3 is a parametric EQ not a graphical EQ...

 

Parametric EQ's have different "bands" of frequencies they affect... I believe the D3 has three bands...

 

So, as you shift say the middle band, it will affect the low and high band as well since they are all "connected" so to speak...

 

You might just try turning down the gains on your amp that is powering the front speakers...

 

Or, try messing with the crossover settings in the D3 and in the amp if it is setup that way...

 

If it sounds "raspy" I can't imagine EQing helping out that much... I could be wrong though... EQing is a bandiad for something like that, IMHO... Not a true fix...

 

See if the MBQ crossovers have attenuation switches or something...

 

Good luck,

Mark

Yeah the crossovers have attenuation jumpers... go to a lower jumper?

Steve

caraudioforum.com has a tonne of useful stuff

Well I got some test tone stuff from there... thanks a lot for that!

But, any idea on how I use it?

Steve

what do you mean installer? i thought you were doing it yourself?

I had a friend of my father (who has been doing this stuff hardcore as a hobby for years) run the wires (pwr, rca, gnds,etc.) and he setup the amp/freq xovers.

Actually, I was into it with all the door panels off, HU installed, and just felt WAY too overwhelmed as far as where to place all the wiring/amp stuff. So he did me a favor, and helped out. I must say, looking back, Installing the HU seemed to be the easy part for sure!

Where are these settings to change it?

Mode > ISO > Read R

That's what I did initially...

Steve

The D3's EQ is PARAMETRIC not GRAPHIC. So you dont get individual frequency adjustment.

Is that why it shifts? How do I try to lower the high freqs?

Steve

DVD Decryptor works perfectly for me on the Nav discs. Just change the setting from Video to ISO.

Where are these settings to change it?

Quick question,

I was trying to find a test audio cd to further tune my stereo... whether it be a purchase or a download. Any input? What do you guys use and prefer? Any idea of a where I could cop one?

Thanks in advance,

Steve

Hey guys,

Just put my D3 into my '06 Expedition.. that along with MB Quart PCE213 comp's in front, JBL Power 6x8's in the rear, and an Infinity Basslink in the rear for some bass. I got a profile 4x80w amp pushing the door speaks. The installer setup up the system so that the door speaker handle the mid-to-high freqs., while the sub does the bass.

My problem is that the high frequency/tweets are like sandblasting my eardrums! Like really raspy at times... and not at ridiculous volumes or anything.

So I decided to start tinkering with the with the D3's EQ.

I'm trying to make the custom 1 preset work. Within a certain band, I'll adjust a specific frequency to my liking... then when I move to the next frequency over, it shift a bunch, including the freq I just set. What's up with that? What's the trick with setting this up? I tried looking to the manual for the answers, but it doesn't go into enough detail about EQ'ing. Any help would be GREATLY appreciated. I was also wondering about test cd's for tuning stereos, but I think I'll just post a separate thread.

Thanks in advance!!

Don't use DVD Decryptor. It's meant for movies, not data. Use a real ISO program and a real burning program.

Ok, I have MagicISO, but I'm working on getting UltraISO. What settings to do I need?

Steve

I used UltraISO to make an image. Then I used Nero to burn that image. Worked fine on memorex DL using an HP DL burner.

 

Check the error on the burn. I bet it's because of the DL split. When you try to make an image using something that's meant for movies, it can sometimes mess up.

So when do I make the split for? The error comes up around the 4+ gig mark...

Steve

Hey Guys,

I searched around on how to backup the nav disks. I used IMGburn, which is just a newer version of DVD Decrypter ( which gave me an error when inserting the nav). I read it to an image file. Then I put in my DL DVD to burn.... got an burn error ~50% through. No big concern, because I have had some problems burning with DVD Decrypter in the past. So I loaded up Alcohol 120% Loaded the image to burn, via the .mdf file.... same problem. Any idea?

Thanks in advance,

Steve
