The magazine _Audio_Visual_ did a comparison of separates which included
MBQuartz, JBL, Polk Audio and Boston Acusitcs.  It rated JBL the highest,
then Polk Audio with both BA and MBQ after them.

I have the clipping if anyone wants specifics.

I am trying to improve the sound quality in my standard
cab 1984 Toyota pickup.  
Space limitations and horrible stock speakers make me
wonder about a setup
with a 2-way crossover and a small 6" subwoofer behind the
passenger seat. A
small amp should be sufficient to drive the stock speakers
for anything above 120hz or so, while the bass may do well
with 20 to 40 watts.  I am currently using a pretty nice
tape deck with Dolby C (but no CD input), although i may
also want to add a 6-disk changer one day (do they skip
bad in a stiff 4x4 like mine?).  Is there anyone out there
who has messed with Toyota standard cab installations? 
also: my budget is quite
limited!

thanks for any input.

In considering separates for your car, I would like to recommend the
MB Quart 215Cx's.  I have had the Boston Pro-Series 5.2's in my car
and the Quart's are a much better speaker overall.  The speakers have an
overall better frequency response at both the lower and higher end.  In
most speaker comparisons that I have seen, the Polk Audio's are not
even rated in the same category as the 5.2s and 215CXs.  The Quarts
also present a much easier installation.  This is important if you are
working with limited installation area, since the Boston 5.2's are actually
6 inches in diameter, and have a deep magnet structure. This magnet
structure caused me to have to use a spacer which can be very incovenient
depending upon the location in your door.  I think that it would be worth
the
time and effort to look into the MB Quarts.  There are several local shops
which sell the Quarts including Absolute Autosound (Route 1).

 Yes, it's probably normal for your cd's to warm up and possibly get
hot.  All of the disc players I've noticed (Alpine, Kenwood, Sony, and
Pioneer) have a warming effect, so I wouldn't really be worried about
it.  It's just like a tape deck I guess, ever notice that the shell of
the casette is warm after leaving it in the head unit or playing it for
a while?  Also, if there is a built-in amp, the temperatures would be
slightly warmer naturally, since there is very little air circulation
behind the head unit.  But, always take out your disc's from your disc
player when you leave the car, you could screw up your disc player and
disc if it's left in there on a hot day (and with a hot cd player hehe).

I suspect that this is a problem with high power decks, as CD circutry
is pretty well intergrated and draws very low current.

Most of the decks we sell are passive (line level outs only, amps 
required) and they don't heat up at all.

Otherwise, it could be a grounding problem, giving a high resistance path 
to ground though the mounting bracket or components.

Could this overheating be due to the installer messing up the heater ducts
or something or is it due to overheating amplifiers in the head units?  I've
had NO problems with overheating, but then again I'm running an outboard
amp so the player doesn't have to push alot of current.

been used. I beleive they are the XTR series. I bought them at a
Highland superstores liquidation sale. They sound great and look
great except that one speaker is missing a dust cover. I paid $75
for the pair so I estimate that $60 is fair. BTW does anyone know

I think you might be right. I have a Sony 5180 and a

It would be nice if the detachable face units came with a "dummy" face

Thanks to all those who gave suggestions.  Most people recommended using some
type of wax to fill the scratch.  There also is a commercial product made
especially for this purpose.  I decided to do nothing, and suprisingly, it has
gotten a bit better!  It rarely skips on that particular track now.  I think
that the scratch has somehow gotten filled with particles in the air or from
sliding it in and out of the disk wallet I use.

Keywords: hi/low (preamp) inputs, lousy support

I recently purchased a  Sherwood XQ-1102 passive equalizer for my truck.
The reason I chose this product is because it is advertised as having the
following:

	Two sets of inputs.  Primary set will accept either high
	(speaker) or low (preamp) inputs as selected by a simple switch.
	The secondary will accept low (preamp) inputs only.

	Three set of outputs. Rear, front and sub-woofer.


The set up is a stock am/fm radio (Mitsubishi pickup) connected to
primary input of the EQ via the speaker outputs of the radio and the
primary EQ inputs with the switch set appropriately, a portable CD
player connected to the secondary input of the EQ, the EQ outputs are
connected to two Jensen amps that drive the front and rear speakers.
No sub-woofer yet.

My problem is that I can not get the primary (switchable hi/low) inputs
to work with my radio.  I have connected the speaker outputs from the
radio to the primary inputs and set the switch to high.  I can get the
cd player to work through these inputs but the switch does not seem to
have any affect.  I have gotten absolutely nowhere with the (psuedo)
techs at Sherwood.  I thought the switch was defective, returned the
unit and purchased a new one with the same results.  Questions:

What am I doing wrong?
Has anyone else ever attempted to deal with the techs at Sherwood?
Is there something else on the market that will do what I am trying to do?

I am totally frustrated.  If it weren't for the fact that I can not find
a similar product on the market I would shove this thing as far as I
could up Sherwood's 'dark side of the moon.'  They know not what customer
service is.  Any help would be appreciated.  Please email responses.  I
will be glad to respond to anyone else that is interested.

You are most like;y in the situation talking about a simple pin switch in
which case would not work for speaker configurations.  AS I know, most vans
have protected housings in which wires will follow thought and will not wear
out with the opening and closing of the doors.  Just like the housings found
in doors with loom tubing or rubber tubing surrounding them.

If there is none, the drilling a whole in a safe spot and putting loom tubing
around it will not hurt at all.

 Well, now that everyone is back from Christmas, it's time to back to
 some serious Car Audio discussions.  How about - IMAGING

 I think I may have a small imaging problem.

 I have components in the front doors with coaxials and small subs in 
 the rear doors, bi-amped, and all crossed actively.

 Alpine Australia has a new test CD that has a track for testing imaging
 with a voice that moves from LEFT CHANNEL to LEFT CENTRE (Aussie spelling)
 to CENTRE to RIGHT CENTRE and then to RIGHT CHANNEL.

 When I sit in the driver's seat, I hear:

   LEFT CHANNEL  - voice is low to the left on the driver's side window
   LEFT CENTRE   - voice is higher, about middle of the left roof pillar.
   CENTRE        - voice seems to be coming from everywhere, not just 
                   from the center of the windshield - problem area?
   RIGHT CENTER  - voice is about middle of the right roof pillar.
   RIGHT CHANNEL - voice is low to the right on the passenger's side window.

 If I sit in the middle of the front seat, the CENTRE voice seems to come
 from the entire windshield, not a tight localized spot like the other 
 voice positions.  The best image is from the middle of the back seat.
 There the voice moves from extreme left to right like it should with a
 tighter but still slightly broad centre.  The image also has alot more
 DEPTH to it from the rear seat.

 Is this normal or is this broad, omni-directional centre voice something
 that can be corrected by a center-channel speaker and/or image processor
 like the Audio Control ESP-3?  If so, what size speaker should it be?
 What brand?  type?  freq range?  power?  I have a small space in my dash
 that might take something as large as a 4"x6" plate.  Are there any 
 other image processors that support center channel?

 Or any other advice, something I may have missed?


 Thanks in advance.

The Dec 92 issue of Car Audio & Electronics rated 7 sets of separates, which
each consists of a 6.5" midwoofer and a tweeter.  The report included the
Boston Acoustice Pro Series 6.2 (probably very similar to the 5.2), as well
as some Polk speakers (don't recall the names).  The report also included
speakers made by Blaupunkt, Clif, AVI, and a few others (not Quarts, tho).

Anyway, the report's not in front of me (obviously), but I thought it had
rated the Polks very high on this list.
