these day's I'd like to see some dumb*ss with a couple of 15"s and a few
hundred watts run a square wave @ 20hz through them at full bore.  Can
you imagine that with 8 15"s?  I wonder how long they would last :-)  It
would be an experience for sure.  Just make sure you're nowheres near

assistant: It really is amazing sometimes how dumb people could be.  Without specs
on the Bronco, I can't be sure, but I would be AMAZED if 4 12"s in
2 HVCD enclosures didn't blow away the Bronco.  The problem with having
so many woofers, is that it's highly doubtful that these people are
putting in high quality equipment (and can afford it).  Not only that,
it's doubtful that they can make an enclosure big enough for 24 12"s
that's properly sized and actually fit it in a Bronco.
You're also right about getting decent stuff at low cost.  My friend
picked up a JBL (GT series?  QTI?  I forget) 200wrms*2 for $200.
It's a sweet amp for the price (even the normal $350 price)  I've also
met a guy who had 2 12" URBANS!!! in his car and actually WON 3RD PLACE
at an IASCA competition.  (And no, the competition wasn't that small.
I'd guess there were about 40 competitors he was up against).  Of
course, he had about 400lbs of sound deadening material in the car, good
placement, and everything set up correctly.

assistant: Well, my Clarion unit says 30x4 on it as well, but that's the
peak rating with headroom.  The rms (average) reading is more like 15
watts for those units.  As for distortion, distortion is always given
at a rated output level.  In this case, it's given for the full 30x4
maximum rating.  It should be *much* less at lower power levels, which
you'd normally use it at.

     It'd take more than ohms law.  Actually, I can tell you all there
is to know about ohms law.  V=IZ.  That's all there is to it.  Some
reading on KVL, KCL, how loads combine and especially transistors would
be much more helpful.  Then again, I have a degree in Electronics and
I still wouldn't call myself an expert on amplifiers.

     I disagree to a certain extent.  If your goal is simply
reasonably loud decent quality sound, there are some 6x9s that do the
job quite well.  Blaupunkt's 6x9s sound very nice.  We're not talking
"high end," but then most car systems don't approach that anyways due
to the environment.  However, they're a huge improvement over most
factory systems, including some JBL and Bose crap I've heard in
Lincolns.  Check out the August Stereo Review's opinions on Blaupunkt
6x9s.  They measured pretty flat (+2.75dB on axis).  That's better
than most home speakers.  Of course that doesn't tell everything, but
mine sound pretty good to me for the car environment and I didn't have
to bother with a custom installation.  I certainly wouldn't call them
an "abomination."  Like all things, some are better than others.

Write your reply.

assistant: No, they're not a "joke."  They may be misleading, however.
They're the peak power readings (usually with headroom).  Peak
readings are just as valid as RMS or even peak-to-peak.  You simply
need to know the difference between them and what they mean.  Peak
power and headroom are definitely important and not a joke.  The
average person often fails to recognize the differences and this is
where the misleading part comes in.  Many companies take advantage of
this fact and purposely give the peak readings.  This usually doesn't
happen with amplifiers designed for the home, which causes the
comparison errors.  Although since Power involves two variables
(voltage and current), they can mislead you even further.  Not all 100
watt rms amplifiers are equal.

Of course, with the popularity of high-current amplifiers, one
needs to be sure of the impedence load that is being used to
compare the amps, since car amps are now rated at 1/2, 1, 2, and
4 ohm loads now, while home equipment is generally rated at 8 ohms.

       OK, that makes sense. But just the geometric considerations make such
imaging a near impossibility. I would think the most one could hope for is
making the speakers disappear. Even though bass is Omnidirectional, in a
vehicle one is always aware that it is coming from the rear, regardless of
what tricks you use to try redirecting it up and off the wind screen/shield.
When cranked up, the bass beats you from behind more than it beats on your
legs and chest, thereby giving it direction, and negating all other effort to
establish the soundstage out front.
       I have seen many of the comp cars, vans and trucks. They all seem to
suffer from this shortcoming. So, for the sake of the hobby, everyone
overlooks it and continues to march.
       I can think of very few environments more difficult than inside and on
the extreme left side and forward of a small sealed chamber with the
requirement that bass only come from underneath or behind you, to try to set
up an image and soundstage. I have heard some pretty fantastic systems that
have somehow managed to overcome this seemingly impossible situation (but at
great expense), with the exception of the directional bass and sub-bass.

assistant: -
Although your ears would most definitely perceive the tweeters
as being louder, the microphone would not.  The mic is working
to pick up sound "pressure", and woofers are needed to move
the air to create the pressure.  That's why when the vehicle
windows are rolled down, SPL drops drastically.

Actually, speakers don't mind distortion at all.  The amp may be
distorting, but the speaker doesn't know that.  It's just getting
current.
What the speaker doesn't want is the current that's just on the
other side of that distortion, which , for the amp, is a clipped
signal to the point that it sends out DC current to the speaker.
That's what melts voice coils.
(When the amp is playing cleanly, the amp is sending AC current to
the speakers.)
