Was there ever a response to the question as to how to increase
the power output by late model Chevy Truck factory radios?

I never saw one!

Also, I understand that these same stereos have line-level
output capabilities.  Does anyone know which connector has 
the line level and if anyone makes an adaptor which mates
the Chevy connector to an RCA type connector?

Thanks,

I am also in the market for a surround processor, but I am looking
for just a surround decoder, possibly with amps for the surround/center

I would appreciate recommendations on such units.  Please send me

Sounds like you either have patch cords misconnected (record and
play reversed in a tape loop) or have the source switch set to
a source that has no signal and you are hearing signal "bleed" to
the selected source. I'd check the speaker wiring and make sure that
you have the correct set of speakers selected on the amp if it
supports multiple pairs of speakers.
   There's probably a few other things to check, but I'm heading

   Then how much will they cost?  If they're not a tape that is already
   made (and "properties are more like video tapes" doesn't imply a tape
   that factories are already set up for), there's no reason to believe
   they'll be cheap.

I don't know how much they will cost, but speculations are that the price will
be the same as ordinary compact cassettes. The introduction price will
probably be some higher. But as I said, I don't know exactly. 

   Having used analog tapes for many decades, we have some idea how they
   degrade.  Since there do not exist DCC tapes that are more than 5
   years old (and probably none that old), there is no experience in how
   they degrade.

But a lot of experience is there for video tapes. 

   I bought a dat deck (Sony D3 dat walkman) for $500; I've seen decks
   for less than that.  The catalog I saw DCC in said more like $900.

Speculation, speculation. By the way, introduction prices will probably higher
than 'normal' prices. DAT had long way passed it's introduction, so I guess
your comparison will change some time later.

   > and I can buy pre-recorded tapes for it.

Please read; my FIRST interest is copying CDs. 

   >And hey, isn't this all about being satisfied? Have you heard DCC your own?
   >Can you judge how it sounds after copying 100 times? 

   No, I haven't heard it, and I'm not likely to.  Why should I move to a
   format that sounds worse than the ones I have, and offers no
   conveniences?

Ahah. Here we can read the final clue. You already made an opinion about DCC
sound, even when you haven't heard it. You seem to hear what you think you
will hear. I guess this will make a fair judgement rather difficult for you
later. 

And what about conveniences? Do you know about the conveniences of DCC? I
don't think so. 

In some respects DCC sounds better than conventional DAT or CD. No audible
quantization noise at low sound levels. Try for that one with your DAT! 

Again, my purpose is not to promote DCC at all. It is just that I hate to see
people talk about things they don't know about or haven't heard, and seem to
made have their final judgement already. 

It's not worth discussing anymore...

I'm curious; what assumptions might these have been?  Is it similar

As far as I'm concerned, the only tape deck to get is a Nakamichi.
However Nakamichi doesn't make a dual cassette, and you'll have to
give up sound mangling features like auto-reverse, unless you want to
spend thousands on a Dragon.

But at $399 US you can buy two Cassette Deck 2's.  Especially since Nakamichi
is blowing out their current charcoal grey line with a new almost identical
black line.  House of Music is San Francisco is selling it for $325.

Nakamichi is the only mass production manufacturer that designs and produces
its own tape heads, and they don't sell them to anyone.  At under $400,
the Cassette Deck 2 will blow any other tape deck, even ones over a 
thousand dollars.  (I'm excluding way out of the way manufacturers like
Tandberg).  Properly biased to a metal tape, it achieve perfectly flat
frequency response from 20-20k Hz at 0 db.  When you read a spec, it's
always at -20 db, but you've recorded enough tapes to know that no one
records music at -20 db.  We record music around 0 db.  It is as close
to a CD as you will ever get.  The only thing it lacks is the dynamic
range of a CD.  Supposedly, CD dynamic range is beyond the range of the
human ear, and metal tapes are just a tad under.

So if you're going to spend anywhere between $200-$3000, it just isn't worth
getting anything but a Nakamichi.

Have a Day!

I don't know if this is the problem with your system or not but  you
may want to consider it.  Sometimes poeple stack their stereo 
components on top of their speakers and when the volume gets high 
enough it vibrates everything including the cd player which can 
cause it to skip.  Sometimes it doesn't take much volume to make
this happen.  So, if your stereo stuff is on top of your speakers
you might want to move it.

Also, I don't know about their CD players but a few years ago, when
I was in high school, I had a Fisher Studio Standard tape deck and
it was a total piece of crap.  I returned at least three times and
each time they gave me a new unit ( I opened the box each time).
Every time the deck died, finally I gave up. This may be your
problem too.

Good Luck,

Grego has a good point regarding matching amplifiers to the purpose, ( for
example, putting a heavy duty solid state amp on the woofers and a tube amp on
the tweeters) but I'd argue that if you have two identical stereo amps, it's
better to devote one amp to each channel. Here's why:

In a two-way system, (I'm assuming the use of low - level active crossovers
preceding the amp inputs) the woofer will be doing most of the
work, and putting most of the load on the amp's power supply. Separating the
amps by channel will let both power supplies in on the act, giving you the full
benefit of both. Even if a strong bass transient causes the power supply rails
to sag, there's still no danger of driving the tweeter channels into clipping
because there's no way a music signal will drive the tweeter side of the amp
anywhere near the rail voltages. An added benefit is a reduction in crosstalk,
since you have completely separate (all the way to the wall socket) amps on 
each channel.

I would definitely recommend bi-amping over bi-wiring; it's much easier to get
close-to-ideal performance from an active crossover than it is with a passive
one. Also, in a bi-amped system, the amplifiers are directly connected to each
individual driver in the speaker system. Two benefits resulting from this
arrangement are 1) the amplifier can better control the speaker element it's
driving, and 2) no power is wasted driving the crossover network.

Have fun!

    If you have a receiver you may want to look at the M&K
    subwoofers.  These have power and you can drive them with either
    a preamp signal OR the speaker output of your receiver.  If you
    do the latter, they are roughly 200 ohm impedance, so they don't
    suck too much power from your receiver (they just pad down the
    power and feed the result to the built in amp...)

    Velodynes are also nice, but not quite as easy to hook up in a
    receiver type system unless your receiver has a separate
    subwoofer preamp output.  (In which case the choice between
    M&K and Velodyne would be sound and furniture styling...)

    By the time you buy the HSU's and amplifiers, you have spent as
    much as the lower end Velodyne or M&K...either of which will
    rattle the walls better.   This is not to bad-rap the HSU's.
    They sound "ok", but nowhere near the powered models I've heard.


    You really ought to go listen to Star Trek, Top Gun, Apocalypse Now,
    Tron, Fantasia, Spinal Tap [ >:-) ], Batman, etc. on a system
    with a good powered subwoofer that offers flat response down to
    20Hz or lower.      

    If you want killer sound, buy two Velodynes or M&K's and put
    them in different room locations to help with standing waves.

    I'd avoid the cheapest Velodyne and M&K models, they only have
    about 50-60 watts and only are flat down to 30 Hz or so....but
    either make has higher end models that are flat to 20, and some
    down to 15-18 at room-shattering levels.

  I'm sorry Chris, but that is wrong. A Zobel is a RC network to compensate
 for the increase in impedance at higher frequencies. A uncompensated woofer
 can present an impedance of 20 to 40 ohms to the low pass filter at 2 - 3 KHz;
 hardly what you have computed your filter. Using a RC network in paralel with
 the woofer you can maintain a stable impedance and therefore your low pass
 will behave as expected.

Records : 78 rpms from the 50's; 33 rpms from the 50's - 70's (if you are

Hats: I don't know the proper name for these hats so I'll do my best to describe

      others are the kind that are flat when they aren't being worn.  (Like in
      the old war movies, when they weren't being worn, they tucked the hat in
      their belt) Sorry this is the best I can do.  Oh, they're from the
      Biddeford, Maine area.

Avon bottles: These are the parfume bottles that are in various shapes like a
              pipe, a coin and there were some other weird shaped ones.  I can
              get more details if there is intrest.

Any general info on any of this stuff would also be great.
