	My suggestion for a CD changer would be the Sony UniLink or
Kenwood.

	I presently own the Kenwood 730 and the C600. The 10 disc
changer is very small (It can fit in your glove box). I don't have it
mounted, just on top of a blanket and it never skipped.

	About the Sony UniLink, they don't skip, I believe the early
ones did but not the new ones. (This is just a thought). The only thing
wrong, I think, with Sony is the user controls. They are a little
difficult at first but I guess you get used to it.

Hi all,

    You have probably seen my messages on the net in the past regarding
speaker placement in an '85 300ZX GLL (six speaker model).  I have made
several queries regarding crossover lobing and phase shifting with no
responses to date.

    Is there anyone out there that could help me on this.  I have
directed queries outstanding to a few people.  Could you please forward
mail or better yet, post on net.  This is a topic little discussed, but
of utmost importance in creating an image without any holes or hammers.

I have just read CSR and they unfortunately did not discuss it;
placement solves problems.  In a stealth system...yeah right.

I currently have in mind a Vifa D19AG that's 8.7 ohms at four and a half
K.  Bottom end is by Peerless running  5 ohms at ditto.  Current designs
are third B's and 4th L/R's with an overall shift of 25 degrees, woofer
and tweeter wired out of phase.

Can anyone help!  I'm about to pull my hair out and splurge on a XESp1
and x1.  God help me if I buy that gaudy blue; it clashes with the
green of the dash.

Anyone up for it.....                              Thanks in advance.

                                    Chad Thomas

PS.  Just kidding on the Sony.

Hola,

I've been considering installing and/or building a subwoofer, and I've been
wondering about the tube subs out there.

Has anyone installed one in the trunk of a car? (I have a Mazda MX6) I've heard
that their best use is in a hatchback or truck. I'd like to know if anyone has
had good results, since buying an amplified one seems to be a pretty cost-
effective way of adding a sub.

I would also consider building one, and I've noticed some discussion to that
length on this forum. My 2nd question is, how does one attach the speaker to the
tube, if say, you are constructing this out of a cardboard tube?  Maybe I'm
being an idiot, but it doesn't seem that you could effectivly use screws or 
bond metal to cardbord.

Anyhow, any help on this would be great. If there's a FAQ on this, maybe
someone could point me to it.

   Well, I'm using Pheonix Gold and have no interference problems, but
using a cheap home-made cable might work. Notice I wrote "might". You may
open yourself up to line noise using cheapo cable, but if it's cheap
enough to just give it a try in your system (i.e. you can handle tossing
it if it doesn't sound good) then give it a shot. If you do, you will
definitely need two conductor cable for each channel - preferably the
shielded type (don't know Radio Shack's part #) where the shield is the
ground conductor as in a normal patch cord:

     ----\_____________ground conductor_____/----  shield (-)

      ===|~~~~~~~~~~~~~signal conductor~~~~~|===   signal (+)
          __________________________________
     ----/                ^                 \----

                                               +--- RCA plug

   Both conductors are used to carry the signal, but I've usually heard the
center conductor called the "signal" conductor. Is this description clear?
Anyone who has better wording... feel free to make corrections/alterations.

well, it will only be as accurrate as the measurements which you
feed it. as it seems that many manufacturors do not have a high
quality control, as well as "fudging" the values....{ no names
will be mentioned } for a accurate calculation, one would have to
measure the individual speakers, and then use THOSE values. 

however, i have had some strange results out of perfbox. whether or 
not they were just some random error, a mis typed entry, or a actual
flaw in the program is undetermined. i usually use my own program
{ with help from other people } for my calculations. if one knows 
anything about pascal, C+ or even using a good spread sheet, one can 
develope a program to calculate dimensions, port lengths and the 
like.

**********************************
* Uneven left/right sound levels *
**********************************

Hello, this is my first post on this net.  I have a Sony D-2 walkman connected to my Blaupunkt 4x30W amp using the Blaupunkt 7pin Din connector.  The other end of the Din connector has 4 RCA jacks.  Also, the Din connector hooks to a preamp that then goes to the main amp.  This preamp also has my factory radio hooked to it through the other inputs: the high power ones.

It seems that two of the RCA jacks are for the left channel and two for the right.  In other words, plugging a source into one of the (say) left jacks ends out playing through both the front AND rear left channels.

So... I simply chose 1 left and 1 right jack to hook up the CD player.  But the problem is that one channel plays louder than the other - significantly.  When I reverse the wires (plug left CD out to right amp in), the louder side changes to the other side of the car.

HELP!  What's the problem?  Is it the CD player, or the amps, or maybe the preamp that the Din connector hooks to?

My present solution is to put an attenuating potentiometer in the louder input line to even out the channels.  What resistance should I try?  And is this is bad idea, or bad solution.

Any help is much appreciated!

Quicksilver!  (Andrew).

It's the Pioneer FH-M75, no I don't have one.  Nor would I spend the $$ 
for it, for the money they want for one of these you can get a Cassette/
CD Changer/AMP...

Features of the FH-M75 (from catalog)

	4-channel high powered double DIN Compact Disc with Multi-CD Controller
	Auto-reverse Cassette
	Supertuner IV 
	Built in 7-band EQ
	and remote control

	The unit has the "auditron" feature, which drops out the vocals of
	a song while leaving the instrumental parts in tact.  This Voice
	Canceller makes you the lead singer on all your favorite songs.

	The FH-M75 also includes an enlarged display, stopwatch, alarm clock
	functions, as well as automatic flip down face panel.  The FH-M75 is
	so advanced it even demos itself.

I must be one of those NOT having skipping problems. I have a UniLink

has about the stiffest suspension out there. It has skipped once in
4 months. DON't get the RF interface, tho, spend the money and get

I used the Radio Shack dual patch cable.  They have 3 ft (R/S #42-2354) @
$6.99, or 6 ft (R/S #42-2355) @ $8.89.  Splice them end-to-end with RCA bar-
rel connectors (R/S 274-1553) @ 2/ea.for $1.39.  Don't bother with their new 
dual connector #274-1548, they're not cost-effective.  Figure out the total 
run of cable and make up your own with the splicing connectors and 3 or 6
foot cables.  I've run video thru this stuff without noticeable bandwidth
loss so I figure if it's good enough for video, it's good enough for audio,
particularly if you're driving from a low-impedance source.  The connectors 
aren't gold-plated, but the electrons don't give a damn.  All-in-all, you 
get a nice cable, color-coded red, green, black, and yellow for your four 
channels.  The judges at a car audio "sound-off" may snicker, but I doubt
seriously if they can tell the difference between the Radio Shack stuff and
your $80 "top-end" supermonsterspecial wire.

BTW, neither myself nor HP endorse Radio Shack.  I just feel they're a
nice local source of parts on a Sunday afternoon.

	I would just get the cheapest radio you could get. Because you
want something in there when you sell the car.

	I would then get an after market radio and speakers. Try doing
it yourself if you want to otherwise get it done by an installer.

Keywords: subwoofer placement vs. sound and performance?
Date: 1 Sep 92 18:28:00 GMT
Organization: University at Buffalo
News-Software: VAX/VMS VNEWS 1.41

Questions:
How does the placement of a subwoofer affect its sound and performance?
Assuming that it is installed in the correct size enclosure, for ease
of argument, let's say an infinite baffle or a sealed box (second order)
enclosure, how will a subwoofer perform in two different cars, say for example,
we have two 10" subs mounted in an infinite baffle setup in the decks of two
different cars each with different interior volumes, one very big and one 
rather small. Will the sub perform differently?  Also, how much would the difference-
   volumes of the trunks of two cars affect the sound quality; how sensitive 
are free-air subs to trunk volume differences?  Will vibration from the drivers
affect my rear window and/or third brakelight at all?

Part Two:
What about when the drivers are mounted on a baffle against the back seat in
the trunk?  How does having the sub fire into the seatback affect its 
performance?  Does the resistance of the seat to air flow cause problems not
found if another scheme is used?  How do you keep the board from vibrating
against the metal behind the seat?

Part Three:
Seat or deck, which produces the best sound quality?

I hope these questions start some interesting conversation on the net. I also
hope some one has answers to all of these questions since they are typically 
unaddressed, especially by dealers in my area.
