I just called Crutchfield hoping to get some information on Proton, and
boy did I ever.  Here's the scoop: Proton is dropping their car audio
line, which is why Crutchfield is carrying their equipment at such low
prices.  Crutchfield is sold out of the 271 passive eq/crossover, and
they are also sold out of the CA-490 amplifier.  However, two of the
CA-490's were returned in the 30 day free trial period; they tested
them, and they checked out as brand new, and so they're selling them as
new, but discounted an additional $20.  I bought one of them - the
2/3/4 channel, 30x2/60x2 (or 60x2/120x1), 100dB S:N CA-490 - for the
bargain basement discount price of $179.  There's just *one* left in
case any of you want to buzz Crutchfield...

After I get it installed (with my new 14 ga. StreetWires!), I'll let
everyone know how it sounds, etc.

Hi all,

I am in need of a program for designing speaker enclosures.
Is there an FTP site that contains these kind of programs? 
Also where/how can I inquire about the FAQ for this group?

Thanx,

Actually, now that I think about it, according to good ol' Mr. Kirchoff,
wouldn't each driver see the same voltage but (roughly) half the current,
meaning the average power per driver would be 15 watts, for a total of
30, and not 30 per speaker? Or are you saying that since the two are
essentially in a parallel combination, that the amp would see 2 ohms and
deliver twice the current, so each speaker would get half of twice, that
is, the original 30 watts?

G'day Netters,

I would like to hear from anyone has experience with these amps
 - whether by ownership, have friends who do own them, auditioned
them while comparing with other brands, etc.

I'd like to know how highly do audiophiles rate them, do they
give the famous warm fuzzy feelings, etc.

I'm looking at amps for powering a pair of 8 ohm woofer/mid-ranges
rated at 100 watts rms. and a pair of 10 inch 4 ohm sub-woofers
rated at 180 watts rms.

Thanks in advance for any replies ( emailed or posted ).

    I hope it was not.  The same a**hole has been driving around in the
area I live in with a 89 Dodge Pickup.  Fine.  I just don't like
hearing him blast rap at 2 in the morning while I'm trying to sleep/study.
I asked him to keep it quiet, he told me to "fuck off".  Called the 
cops.  They want no part of it, this is a "university problem".
BTW, loud is as in you can hear it (and almost feel it) for better 
than a football field's length. If he doesn't stop, his truck may just
have some problems.
   I have a setup that probably could be played annoyingly loud. I
chose not to, namely because I like to be able to hear things, and
I don't expect other people to like Metallica played at high
volume.  What it really comes down to is just be considerate. It's 
a really difficult idea for some people.

Well, my site continues to be having problems. Many of my posts on both the

spread to my mail deamon. I am having trouble with outgoing mail, and 
incoming mail is being cropped. Since I also have two major exams later this

Well, I'm not Brian, but I'd like to add my opinion here.

I believe most people prefer front-primary imaging because it provides
an illusion of "being there"; like you're at a concert and the sound
stage is in front of you (when was the last time you went to a concert
and stood backwards through it?).  However, I personally prefer rear-
primary imaging because in most cases (and especially my application),
it allows for far greater sound quality (my 6x9"s plus self-powered
sub versus a 3 1/2" mounted high and 5 1/4" mounted low).  In reality,
I tend to balance everything so that my ears, in my natural driving
position, are the exact center of the sound - move slightly forward,
and the stage is in front of me; move slightly backward, and the
stage is behind me.

How do other people here feel about imaging? What do you do to create
the image you want? What equipment do you have? I'm very interested in
hearing about people's specific applications, including problems they
have and how they've (attempted to) overcome them.

Maybe it skipped so much (that's a lot for an in-dash) cuz it's a Sony.
I don't know what the numbers are, but I heard that Pioneer and especially
Kenwood almost never skip.  And someone I know has a Pioneer 6-disc-changer
that is only resting on a towel in the back of a truck, and it never skips.
I personally have a JVC in-dash, and it hasn't skipped in literally months.
Well, not from the car jarring; only because of scratched discs.  The only
times I remember it skipping were crossing between two parking lots that 
weren't really connected, and therefore weren't meant to be crossed.

     I think his point was that the amount of false alarms in general have
dulled the public's sensitivity to the situation. Most of the time the owner
of the car is not going to be within hearing distance of the alarm, such
as in the case of the jeep above. If you hear a noise frequently enough,
you will get used to it and tune it out as background noise. So people
in general don't pay that much attention to alarms anymore. Even though you
may have had your alarm installed and adjusted to perfection, YOU are the
only one who will know this (except for the person who installed it). 
Everyone else will just assume that your alarm went off because your car got
bumped or something, and will ignore it. That is why the original poster 
suggested a pager as a solution.

Since the carjacking problem is itself a response to the prevalence of car

You know, rather than simply kill the engine, I think it would be better to
cripple it.  A thief who steals a car only to have the alarm sound and the
ignition die soon afterward will connect the two and may go looking for the
alarm and its ignition kill relay.  A thief who steals a car but finds that it
stutters and coughs above 10 mph or so might simply assume that there's
something wrong with the car, and abandon it. This also gives the car a better
chance of being found intact than if the engine simply dies in the middle of
traffic. 

But again, this relies on the thief not knowing about the new type of alarm.  
As soon as such alarms hit the street, thieves would be wise to them.

I prefer front imaging.  To me, it seems to be the only way to have a
good sense of stereo seperation.  As well, I find rear-imaging systems to
be fatiguing and, in my experience, more dangerous.  Now, before you all
freak out about how I could possibly consider any kind of imaging to be
dangerous, I'll explain myself.

Having the driver's attention, even if it is only his (her) aural attention,
drawn into the back of the car is distracting. Consider all the other driving
stimuli are in front of the driver.  But that's just what I think.

Still, there is the issue of imaging and soundstage.  A properly set up
front speaker system will _not_ display "sound on the floor" performance.
As well, with correct cross-overs and phasing, the sound from the subwoofer
will not appear to eminate from your trunk.

As for sound bouncing from windshields:  This practice is to be avoided in
general, although your mileage will vary.

But, hey, like a fool, I dropped waaaaay more money on my rear speakers than
my front ones.  Oh well.  Every time I turn the volume down on those rear
speakers, I cringe at the thought of how much money was wasted.

If I were to do it again....

Chuck, 
	They still do make one changer that works on the XR series...
the CDX-A55.  This changer replaces all of the following...
CDX-A100
CDX-A15
CDX-A40
CDX-A30
CDX-A2001
CDX-A20
CDX-A10

So you don't have to start from scratch, as long as they still keep
the 55 around for a while... considering it's new now, I would think
that they would too.  If not, the Kenwood, Blaupunct, and Denon
changers are still compatible with the Sony XR series decks.
