Fry's was about $200 more than JR.  The cheapest I could find it here
in the bay area was about $175 more than J&R.  They were the cheapest
of the reputable mailorder houses that I checked out.

Well, I have plenty of opposite experience:

My own 280 gx, still the best sounding bass amp (other than the 250 HCCA,
but that won't drive my 4 ohm load very well), over 4 years old, never
given any more problem than a blown fuse (OK, I turned up the bass too loud)

My friends 280 gx, over 6 years old, all original parts inside, puts out
over 400w before clipping, (measured), never even shut off.

The only things that will destroy an Orion amp are:

1) Low battery voltage. An Orion amp will produce the regulated power
supply voltage inside , even to the point that it self destructs.
IT WILL NOT SAG!!! Low battery voltage increases the load cycle
on the power supply transistors to the point that they fail, but
the output will not change until total destruction! THAT is the 
PRECISE reason that they have the best controlled bass of any
amp on the market IMHO (espscially the 280 gx and 250 HCCA).
PPI amps, on the other hand (the newer ones) will sag somewhat,
relieving the load to a certain extent (but compromising the
sound quality) Fosgate is guilty of this to an even greater extent.
However, the older PPI amps were even MORE failure prone than Orion
for the same reason- the older PPI designs actually INCREASED the 
supply voltage under heavy load!!! (I measured this myself to
verify this) 

2) insufficient cooling . Orion ampr run VERY hot!!! They do need
unrestricted access to air; fans do help somewhat. However,
overheating shut-downs are usually a symptom of (1).

3) bad speaker load. Speakers that bottom out send back low-impedance
transients to the amp. This is particularly bad to Orions due to the
tight power supply regulation! Bad x-overs with impedance dips and
improperly equalized ported boxes can also be responsible, as can
improper nominal impedance (too many speakers etc).

In summary: Orion amps are like race cars- everything must be right
or somethings gonna blow! But, get everything right, and abuse every
thing in sight!!!

My IMHO backed by my 8 years installing,

Regards,
Gordon.

	Reply didn't work.


	Hello,

	I have the Kenwood C600, The guy is right it doesn't skip, (even
when I did get into an accident). Which Sony changer? I don't think it
will skip. Test it out first. shake it around. If it doesn't skip then
it won't in the car. My changer is on a blanket, nothing else hold it.

	As far as other changers, I would only suggest Sony or Kenwood.

	What tuner do you have?

	If your tuner has CD changer controls go with that company
because you would have less connections.

					Hope this helps,

Subject: Advice on wiring
Date: 26 Aug 92 12:34:53 GMT
Organization: National Institute of Standards & Technology

Hello all,

Well i finally bought an amp yesterday.  It's the a/d/s/ PQ10.2.  About
a week ago i posted that i had ordered a PH15.2 from "Sound City".  Well,
they never had the amp in stock, and after waiting a week, i called them
only to find out that they "were on backorder".

Anyway, i went to a local dealer who gave me an excellet price on the PQ10.2
so i bought it.  Now i need advice on wiring it.

	- this amp requires a 10 guage power lead.  if i run a lead of this
	  guage from the battery (fused) to the trunk (with another fuse)
	  how can i add an additional amp & crossover later on with wire this
          thin as my existing lead?  Should i use a heavier guage then split
	  it somehow?  Can this be achived without selling the farm or buying
	  stock in "StreetWires"?

	- grounding.  can i ground the amp to a bolt in the trunk or do i need
	  to run a ground to the head unit? I am really concerned about not
	  having any signal noise.

	- is it me, or are the prices of line level leads (RCA type) crazy.
	  $60 for 5 meters (Monster Cable); i need two pair, that's $120.

	- any tips for routing cable to prevent noise?   


Thanks,

I'd prefer not to be shot down in flames for this but I would like to tell 
others of what I consider a good in-dash CD player for the money.

   I bought a Optimus (pn 12-1987) removable in dash CD player from Radio
Shack.  This unit has all the regular features that you would expect including
pre-outs, programming, and am fm.  

   I installed this in a 17' speed boat that rides really hard in rough water.
When I crash over a wake of another boat this player will not skip unless we hitreally hard. I am really impressed by the performance of the unit.  It cost me 
$277 before tax so I consider it one of the cheaper models on the market.  
Believe me that your car rides much softer than this boat.  Just my two cents.

  I don't work for RS or own stock in them or care if they ever make a dime.

I tried two 'PYLE, DRIVER I's today at a local car audio shop and was not real

There is a new shop in town that sells LANZAR stuff that I would like to get, 
but my budget does not allow it!  The DRIVER Is I tried were on sale buy one 
get one free for $99.95 (This is a nice price).

QUESTION:  Knowing my budget restrictions, am I better off sticking with what I

[questions about alarms deleted]

  Well, I once owned an Ungo Box and really liked it. My set up
was pretty basic and had door/trunk/hood entry detection and
motion detection. The thing I liked about the Ungo is its method
of detecting motion. They wrap a coil of wire around a glass vial
of mercury and run current through the coil. Any change in the
flux of the coil is then due to the mercury moving around inside
the vial. This method allows the motion sensitivity to be 
adjusted very precisely - unlike my current alarm which has two
sensitivities: touch with a feather to activate or run over with
a tank to activate. The Ungo also provides a dash switch that allows
you to choose between two levels of motion sensitivity whenever
you want. The two levels are based on how sensitive you adjusted
the main unit (one less sensitive, one the same).

my opinion (for what it's worth),

P.S. I have no affiliation with Ungo Box whatsoever - just liked
     the product %\)

The Best glue/adhesive to use is 3M 90 spray adhesive.  Don't use the 3M 77
that alot of stores will try to sell you.  As soon as it gets hot, it will
come off.  

PS:  It also works great for making your own speaker grills (To attach grill

There are three Solobaric drivers: S8, S10, and S12.  Here are their
published T/S parameters.

				S8	S10	S12
		
		Rs		3.66	3.58	3.58

		Xmax		8.73mm	8.73	8.73
		Sens.		86	86	86
		Lvc		.496	.479	.600
		

I use Perfect Box to compute alignments and find it very useful.  It
gets you very close to the actual performance but then you have to
tune a bit, especially with small fourth order (ported) boxes.  After
playing with it a bit, Perfect Box gives the following results (all
for sealed boxes):

		Model	Volume	F3	F10
			(ft3)	(Hz)	(Hz)
		
		S8	.33	64	37
			1.0	71	30
			2.0	77	29
		
		S10	.7	58	31
			1.5	66	26
			2.0	69	26
		
		S12	.88	40	28
			1.5	36	22
			2.0	36	21

If the numbers are right, the S12 in a 1.5 cubic foot is pretty darned
amazing.

Probably doesn't.  The lever effect is more drastic the longer the

It would be worth asking what their mounting points and methods were.
I wouldn't be surprised to find a few shockmounts in there somewhere..

No, I'll be avoiding RF connections like the plague.  What I meant was
an actual concealed FM broadcast reception antenna (anyone remember
the windshields with two VERY THIN wires buried in the plastic layer?)
that won't immediately tell the world I have a stereo in the car --
the combination of visible antenna and invisible radio being VERY BAD
for the car since they just go looking for the radio they know is in
there.   I don't care about gain; I live in a town full of 100kW
transmitters so I can live with the antenna completely missing even,
although maybe I could put a tap in to plug in an auxiliary
magnet-mount for road trips.  I also do not care the least about AM
and neither does anyone else in my family.

new cars over the past 10 years, I've never been satisfied with the
sound of the factory installed systems.

What I want in a third-party system is the ability to:

(1) Play single CDs (a changer is not necessary).
(2) Play cassettes.

Are there combo units that do both (and of course include the AM/FM
radio as well)?  If so, recommendations?  

Finally, what if any advice do netters have for dealing with the 
problem of factory-installed sound systems?  I don't want it but it
seems I still have to pay for it.  

Thanks in advance.
