Bose Sheets
The following is a scan of a sheet Mazda mailed me on the Bose Stereo. I had emailed them about the stereo and they said they would send this out if I liked. Here is one side.

good thing I didn't scroll down before I hurt my neck as well :o
edit: thought this would be a good place to mention that Boowana confirmed a in dash 6-disc in the bose system in another thread, regardless of what customer service tells you.

Thanks Hercules for fixing my mistake.

Overall I think the Bose system will be impressive.
A few things that I am concerned about:
1. How does it come up with the sound for the center channel? Does it use some sort matrix alogrithm like Dolby pro-logic or just simple mix-mono. My guess is simple mix-mono which is okay but nothing compared to what the Matrix stereo alogrithms can do like Dolby Pro-Logic II. This Alpine is the first head unit to have it built in.
http://www.alpine.com.au/product_pages/dolby_page.htm
Clarion also makes a device, that I think is stand alone, that can do Dolby Pro-logic II.
2. How's the low bass going to be? My guess is Bose will do a decent job but there is only so much you can do with a couple door-mount 9" woofers and a couple free-air 6X9's in the back. A nice aftermarket add-on sub will be a good idea.
3. How loud will it get before distortion. I have never been too impressed with Bose systems when it comes to really jamming. Sure it gets loud but the speakers and amps usually start to distort before the sound level is as high as I like. This is where a complete speaker/amp overhaul might be necessary.
Personally I hope all I have to do is 2. but some says I am going to want the benefits of dolby pro-logic 2 so I will probably do something more extensive. I'm just glad there is a whole in the center of the dash already.
I don't mean to knock the Bose System (hell, I ordered it). Just I only give it a 50/50 chance of satisfying my picky tastes.

Neddie,
That is the only production car that has it. I had a private listening session with the Volvo at Dolby's both at CES.
It sounded awesome. If the new 300 Hp all-wheel drive Volvo sedan had it, then I would have strongly considered it. The spokeperson said he was pretty sure only the SUV would have it right now.
Pro-logic 2 and autosound are made for each other.

Here's a picture showing the amp in the back:
The size of the heat sinks seem to indicate that this is a fairly powerful amplifier. Especially since the literature refers to the amp as a "two-state modulation" amplifier (class D) which are very efficient to begin with.
With the normal factory system rated at 100W. My rough guess is the Bose system will probably make somewhere in the neighborhood of 175W.
In a small car that should be enough. I'm getting a little more excited about it now.

Velociti,
The frequency range listed by manufacturers is completely up to the manufacturers. Some define the lower limit at the -10 dB while most use the more appropriate -3dB criteria.
With that in mind, the only way to effectively aproximate a speakers low end response is with what are called Thiel/Small (spelling) parameters. They include specifications like: Fs, Qts, Qes, Qms and a few others.
Of all the free-air woofers I've heard, most 6X9 or 9" (or 8") woofers can only go to about 50 Hz effectively.

It is going to be a pity that after buying the car I won't have the same budget I did to put a crazy stereo in it. I'm sure going from the IASCA competition stereo I had (before stolen ) in my Camaro to this Bose unit is not going to please me. Pity I don't have 10k to throw at this car too .
BTW, you'll still be missing a lot without a sub, I can almost 100% guarentee it. You MAY get some deeper bass out of the 6x9's in the back, but depending on what other frequencies they are going to be playing, it'll get muddied. Never been a fan of Bose, regardless of home or car. However my old set up wouldn't most likely even fit in this car even if I did still have it.
BTW, 100 Watts is nothing for a full range system, **** I had more than that going to one 6.5" mid-bass in my system before. I'm not hyped at all about the sound.
...garners flame suit

Dream,
The STANDARD system has 100 Watts. The Bose system has not been specified. I am guessing somewhere in the 175 Watt area. Just a rough estimate.
And I too think that the system will benefit from a sub.
Personally, I think the system will sound good at medium to low volume. High volume might be a different story. The good news is with 9 inch woofers and large mid ranges in general, the speakers should be rather efficient to begin with. Hopefully, that will also help bring those SPL's up a bit.

BTW: 100 compared to 175 is really not all the big a difference, especially since it's driving the signal full range. It'll still run out of juice quick. Just to let you know what I'm coming from, so you can see why it's going to be hard to impress me, I had 150 watts going to each bass/midbass speaker in my system. That's 300 watts for a 45hz-500hz frequency range, ALONE! I had horns for my mids and highs, so they didn't need power at all they were so efficient it was crazy, 25 watts to them would literally make your ears bleed. Then I had 2000 watts going to two 12" subs. That's power...enough to make me get a high output alternator to keep my headlights ON (not from dimming, ON).

hey, i've been checking this forum out lately...newayz, HOW COME THE MAZDASPEED PROTEGE GETS A 450...that's rite! 450 WATT SYSTEM????? we get like wat 200 tops? lol..we pay 10k more and get hlaf the audio

.....and a nicer interior, a much more potent N/A rotary engine, a 6-speed transmission, and a much more attractive (and expensive I assume) chassis. What else should they have added to a souped up, yet relatively cheap sports sedan? I don't think anyone is planning to buy the MPS Protegé because it has a more powerful sound system. Also, if the Bose speakers possess any kind of efficiency, then having 200 watts or 1000 watts on tap will be irrelevant, because it will never be used by 95% of the owners.....

Nine inch door speakers? Do you know of any other factory system with NINE INCH DOOR SPEAKERS??!?!
Digital Class D Amp and NEO magnets?
That is unheard of!
Of course its not going to be an SPL system - IASCA is irrelevant.
Add three kilowatts of amp and sub if you want to, but leave me out of it. (I prefer my ears NOT to bleed, thank you.)
I am amazed at the dismissive attitude towards this system - don't get me wrong (don't get me started!) I am no fan of the pathetic home Bose systems, with their plastic cased 'clock radio' speakers and overworked mid/ported 'bass unit', but this RX-8 effort seemsto be a solid effort. The amp is digital/class d and looks to have lots of heat sink, the speakers are well sized for the interior volume, and the neodymium magnets have obviously resulted from the 'gram taskforce' approach.
The 'Woofer-of-the-Month' in AutoSound and Security magazine was always close to my heart, as was the bloke who wrote it, but take it from me, unless you want to open the doors and entertain the whole beach, or stand outside while a microphone appreciates all the money you wasted, this system IS up to the challenge.
I don my silver Nomex suit and urge one & all to 'bring it on'.
(On a 'sirius' note, I have e-mailed Bose for details of the Satellite radio adapter this system will require to receive SIRIUS, the Ford/Mazda sat system. Film at eleven.)
