Subject: Bose AM-5 or CSW Ensemble



   I'm looking for a good satalite/subwoofer system for my dorm room. 
I've listened to the Bose AM-5 and the Cambridge Soundworks Ensemble
(the orignal one with its two bass modules).  Unforetunately, I've never
been able to listen to them side by side and compare the two.  In my
humble opinion, they both, especially the CSW, sound good.  What do
others recommend?  What are the good and bad points of each?  I know
that the AM-5 cost about $200 more.  But I'm looking for the better
system, not the better value.  Thanks in advance.

Howdy-doody y'all. (Just kidding, we don't all talk like that
here in North Carolina.)

Hello all.

Recently, I had an Alpine 5952Z(I think, the entry 
level cd changer) installed in my `89 Accord SE-i(trim level
is important, I'll explain later). I chose the Alpine
because it could be plugged directly into the factory
system and hidden in the trunk (the controller is mounted
in the ashtray). It cost me a lot of money, but there
is a very small chance that it will be stolen (BTW I got
the cd player for $400, but got screwed on the cost of
the controller and all the interface stuff). It sounds
great with the current setup(This is where the trim level
comes into play). It is a Bose system with an amp hooked
up to 6x9's in the rear and, I think, 6 1/2's up front, 
which are powered by the head unit (the installer told 
me all this). 

I know the next course of action is to install new speakers
and amps, but I want to keep the same head unit, and I 
do not have the money to do it all at once. Any 
recommendations (I want separates up front) on what to do 
and in what order?

I also want subs, someday.

Thanks 
   Mike

   Try checking the wire that supplies the power to the memory,

IMHO, if you have an alarm, skip the led - it's very easy to see a little 
red LED flashing from across a dark parking lot, telling a thief that this 
is a car to inspect closer.  The element of surprise could scare a thief 
away.  If they expect the alarm, they are just going to move a lot faster 
and do more damage.

The same would go for ultra-sensitive shock sensors that will tell a thief 
if you have an alarm simply by tapping your fender.

	I am considering going into debt over a 1993 Acura Integra

	I have currently BA 5.2s, Fosgate 5 1/4 (possibly will sell

 Since everyone knows about the debate over tinted windows, I won't
quote it.  Here's my opinions:  I think tinted windows ARE useful, one
thing is they stop the fading in the interior and keep the car much
cooler (depends on how dark the tint is)
  On some cars, I think it looks much better with tint than no tint.
One example are white and burgandy 92' Accords, before my friends put
tint on it, it looked like crap, but now it look MUCH better.  Some
people would rather like the car looking "clean" so they leave the tint
off, which I like sometimes.
  Some people say that tinted windows attempt thieves.  I guess that
would be so, if I see a nice car with tinted windows, I think it must
have a nice little Alpine for me to thug! (-: hehe
  As with everything, there are those +'s and -'s about getting things,
but ever since I got my window tint, I've been happy.  It offers much
more privacy and keeps my interior from fading...

	I can't speak for the ZL speakers, but can tell you that biamping
a 6x9 can produce decent bass.  I have a pair of Phase Linear 6x9s that
I used to have biamped (30wpc mids/highs, 50wps woofer) which did a 
surprisingly good job.  I could legitimately bass with rap music, using
just a pair of 6x9s.  Of course, the first pair fried, and these now
are just about fried, but as long as I keep them crossed over operating
at 150Hz+ they still do OK.

  In several issues back, CSR or Car Audio had stuff on people who had
  taken cheapo K-Mart am/fm/cass decks, removed the face plate, glued 
  a half CD onto the back and stuck it in their CD Deck.

  They also said that no one would be fooled by a blank plastic plate.

I don't know the pinout but surely you can find an adapter for the thing. I 
found one at the local Fry's Elctronics. Radio shack also has such things but
they don't stock them so you'll probably have to order. Just take the unit into
the store and order what you need. Don't cut if you can help it.

Hello fellow car-audio fanatics =

All this talk of putting big hairy capacitors across your 12V DC power
inputs to your earthquake-inducing amps got me thinking...

High power automotive amplifiers use internal DC-DC converters that step 
up the automotive 12 volts to something around 35 volts or so.  This
high-frequency switching supply is in turn rectified by Schottky diodes
and filtered by ordinary size electrolytic capacitors.

My question: how do you know the internal filter capacitors in the amplifier 
are large enough to supply the audio peaks you need?  Perhaps you need to add 
some more capacitance here also.  Anyone ever look at Vcc vs audio flat-
topping on a dual-trace 'scope?

Other than that, I'd say to quit trying to draw multikilowatts @ battery
voltage out of a 20 foot run of #18 zipcord.

is capacitively loaded. Do the receivers anticipate and
