   I recently started shopping around Denver area elctronics stores and
found lotsa caps quite cheap.  For instance, I ended up buying two
260,000uF @ 15v 18vmax for $4.25 including tax!  Of course to keep the
voltage at 15v it appears that I am going to have to find a couple more.
   The stores I looked in had tons of stuff (and I do mean stuff!)  things
like laser kits, 12v converters, and all the other neat stuff that would be
needed to do about anything in a car.  If anyone is interested in the
particular stores email me and I'll get back to you.  I found mine in the

You might consider selling the CDX-A30 and buying a whole new
changer+controller set.  Someone with an XR-series cassette deck with changer
controls but no changer yet would be well advised to buy it from you, since
Sony is no longer selling them.  The new U series (for "Unilink") changers
won't work with the head units.

This is good, but a far simpler thing to do is to just steal the car
(use any destructive means you like).  Park it on the sidewalk in
front of the nearest police station, or in a bus lane or other place
where it will be towed away right quick.  If any of the neighbors see
you, invite them to help-- after a few nights of false alarms, they'll
be glad to do it.

I've got a `90 Jetta GLI and i began with replacing the rear 4" speakers
with a set of 6.5" component speakers.  This required cutting, however, 
using a larger speaker in the rear makes a world of difference.  If you'd
rather not cut consider dropping in a pair of 5 1/4" in the existing
hole (chech the fit first though).



> I'm mainly looking for advice about a)should I only upgrade the speakers? 

This is where i began, only, decide how far you want to go, so that you don't
end up buying speakers that you'll eventually need to upgrade.

>All of them?

I replaced all of my speakers, although, not at one time. $$$


>Should I get an amp too?

Depends on how far you want to go.  I bought a four channel, and i am
about to buy another for my sub.

>How powerful?

Thats all up to the individual.  I bought an a/d/s/ 4x40.

>What brand (speakers and amps)? 

MB Quart makes a set designed especially for Jetta/Golf, major $$$$ though
IMO.  In terms of amplifier, just get a good one, PPI, ADS, Pheonix Gold etc.


>Is a subwoofer overkill for a car?

A subwoofer is never "overkill".  Do you want to be able to hear all of
the recorded information on a particular cut of a disk, or better yet what
would life be like without the color blue, particularly when everyone else
could see blue.

He forgot the best part...you then take the live wire, ground it, and

WHAT!?!  The cretinous offspring of leeches and palmetto bugs whose alarms
wake one in the middle of the night deserve to have their vision obstructed.
And by stronger means than a sticker, I might add.  Like a nice HIV infected
syringe (available at finer crack houses anywhere) could be used to slowly
extract the intra-ocular fluid from their eyeballs.  Then one could gently
rub the lens of the eye against the retina.  At first they would probably
see incredibly bright sparks.  Then, as the visual nerve endings die, the
sparks would get dimmer and dimmer.  To make them feel better about it,
you could then give then a nice stiff shot of their own EyeFluid (tm).

BTW Palmetto bugs are a cockroach like bug which inhabit Florida.  They 
are wonderul.  Well that's not completely accurate.  P-bugs are to cock-
roaches as Mack Trucks are to Honda Civics.  Wonderfully tasteless, and 
they make a great "CRRUNCH" when you step on them.  Smell pretty raunchy 
too.

Sorry. I thought we were talking about a 3-way system.
In any case, it's best if the driver ranges overlap. This is tough to
do in a 2-way system.

Well, having gotten some sleep, I have figured out what I was trying to say
in another post (regarding crossovers) and am going to have to
post a partial retraction.  Since it is related, I hope you read it.

As for high requency roll-off being more gentle, I assume you are
implying that the system response isn't flat, and you want to avoid
a sharp drop in treble response.  Do I have this right?  In this case, I
would agree, but I thought the point was to make a system with flat
response, so that the roll-off of one driver shouldn't make a big
difference.

Perhaps the idea is to reduce the rate of phase error change?
Since the woofer and tweeter will have markedly different phase
response at the crossover point, this is intended to smooth the mixing?

This problem with a cold unit skipping is often due to cold CD's, not
the actual unit.  I too have an older Pioneer (a 750) and find that it
only skips if I really push the car to its limits (sideways over speed
bumps does it), or play a cold CD.  So, make sure you have a CD inside
to bring with you to play for a few minutes until the interior gets up
to temperature.

I've seen this happen with other units as well so I'm not sure if it's
really any kind of model specific issue.
