Subject: Alternator whine help please?
Date: 13 Oct 92 17:50:27 GMT
Article-I.D.: iscsvax.1992Oct13.225027.7610
Organization: University of Northern Iowa

To anyone that can help, I need it.
I've got a 1986 S-10 and have had problems with my stereo system ever since I
installed it 6 months ago.  I have a Delco Cassette with a speaker level to
line level adapter to run my two Alpine 3522 amps.  I have Alpine tweeters in
the front dash, Boston Accoustics 4x6 in the rear and one 10" Boston sub in a
7th order bandpass box.  One 3522 runs the sub mono and the other runs the four
speakers.  (By the way, I love my Alpines!!!!!!)

The problem is:  Major alternator whine.
It is very annoying and I can't seem to get rid of it.  I have my amps grounded
directly to the cab floor and have my power wires on the right side of the
truck and my RCA's on the left.  The cables are not of great quality, but I
don't think that is the problem.  I have run new power and ground wires for
both the head unit and my amps with no improvement.  Is it from the speaker
level adaptor?  I have a Pioneer DEH-680 ordered and it should be here about
the second week of November, so I wont need the adapter after that.  However,
if that is not the problem I will hate it even more when I finally have my CD
PLayer.  I am also getting an electronic crossover and have heard that some
bring noise into a system.  What should I expect?  And what is the problem if
it's not the adaptor?

One other observation:  the alternator light stays on in the dash until I rev
the engine, and the noise is not present until AFTER I do this.  What is the
relation here?

Any help would be greatly appreciated.

HELLLP!
Ok heres my dialemas.

1)  I have a RockFord Fosgate Punch 45, have had it for a coupla years, and
for the past few months (or longer), The AMP ITSELF has made a VERY HIGH
pitched whine.  This is the amp itself and not the speakers, from inside the
amp!   It sometomes goes away if i remove the screws and shake it (so i think
its something loose or broke internally).  The pitch changes sometimes too,
sometimes it changes with the music sometimes it changes with the
alternator?!?!?!?!
		Anyone have this happen before or know a solution?  I asked
JC a while back, but that was a while ago and he couldnt figure it out (any
ideas now JC?)

2)  Call me clumsy, call me in a hurry call me drunk.  But I got out of my
car (Passenger side, wasnt driving) grabbed my Sony XR-7070 pullout, and
dropped it from about 3-4 feet onto the pavement.  I have dropped it before
but not from this height, usually onto my car floor from my seat.  
	2 things went wrong
	1) The lever to pull out the unit wouldnt stay down, but this was
		easily fixed, by removing and tightening screws.

PROBLEM HERE!!!!!!!!!
	2) The Locking Rewind does not lock, altho Fast forwad does.
		

Is this something I can fix, (with a little help from computer/tv/whatever
fixit man Dad), should I take it to a shop, should i just pop off the top and
take a look then decide????

My dad might be able to fix the amp and teach me how to do it as well, so i
suppose i could pop the top off anf look at it as well. 
OR SHOULD I NOT?????

With all the talk about Alpine on the net lately, I've been thinking.
I have the chance to pick up an alpine 3519 amp for $30-$40.  It DOES
still work but is rather old.  I would either run midbass/highs or just
highs off this amp.  

	Oppinions about the deal??  Worth it?  Waste of money??

I believe this amp is 30 or 35 watts per channel.  I have heard some alpine
systems that I was VERY impressed with.


Thanks,

Good God!  I never saw so many messages.

Thanks to Tim for planting the test to Dosgate!  Ditto to Boing, the
Infoman, Travis...et al.  I had honestly thought that the cold had
finally gotten to the server and had frozen some nodes.  Thanks to all
in the past and future...

Travis..I subscribe to CA&E and have been drooling for a month.  Funny,
but Blade is just 5 kms north of where I live, but I've only seen one
test car.  Can't find anyone.  Thanks for your response.

By the way...Many of you out there know a lot more about lobing than you
would care to admit.  The discussion on relative phasing of drivers (180
degree, 270, 90 et al.); you are looking at orders.  The directional
lobe is formed by convergent waves of air pressure between the two
drivers at or near similar frequencies.  That's partly the reason why
some home speaker systems sound better than others when the listener is
in the standing position.  You guys know it!  Regardless, I've dropped
the idea and decided that perhaps five years down the road when I can
afford an XES-P1/X1 combo, I'll tinker with it then.

Thanks anyways...

There is a way to fool the speakers...you can stuff polyfill into the 
enclosures.  The ideal amount is 1 pound of polyfill per 1 cubic foot.  
This will gain approximately 10% (I believe).  The only problem is that you 
will not gain enough with this technique...1.17 still isn't close to 
1.5ft^3.

You might, if you have the boxes built, try this and see what they sound 
like.  They won't play as low as they would in an optimally tuned 
enclosure, but they will have quite a bit of "kick", which some people 
find desirable...

Another solution, if you haven't built the boxes yet, is to build an 
isobarik enclosure, but then you will lose the advantage of having two 
speakers.  You would only need half the volume that one sub needs, but 
there is no sense in doing this because you have the room for one sub, and 
unless saving the space is VERY necessary, the cost doesn't justify the 
amount of space gained.

Good luck in finding a solution!!

   It could be that your line outs or some of your audio lines are being
run next to the brake light wires, probably along the threshold. If that's
not the problem, then it could have something to do with the same pop
you'd get indoors when you turn on an electric mixer or some other motor
like that. Sorry this isn't a solid answer, but I've been "out" of the
car audio scene for a while.

   While we're on the subject of weird pops... My stereo makes a weird
"pep-poop, pep-poop" noise that is noticable only when the motor is OFF,
even with the volume down all the way. Hmm, I can't remember if it happens 
when the radio is on, but I know it does with a tape running.
   The deck is a Yamaha. It runs to two amps which I'm too embarrassed
to mention here. Okay, okay. A Craig and a Sony which I bought from a friend.
Life sucks when one has to decide between home or car audio, computer stuff,
drums and electronics, girlfriend, etc...

You can gain about 25% in "virtual volume" by stuffing the enclosure 
tightly with insulation.  I usually use quilt batting, but all types of
fiberous materials can be used.  Make sure to NOT stuff the stuffing
too tightly near the driver.  The entire enclsure should be stuffed.
Just lining the walls will not give you the volume increase you are 
looking for.

Just got Perfect Box, and it is a very nice program!  I entered
the Kicker C-10's stats, as well as the Pioneer I am trying at
the moment (10" Maxxial).  Actually, the Pioneer even looks
better than the C-10 on the Amplitude v. Frequency plot!  
(for a vented enclosure of my box size, the Pioneer is -3db at
about 48Hz, and the Kicker at about 51Hz.  The Pioneer is -10db at
32 Hz, and the Kicker at about 34Hz)

Well, my first (quick) question is, how do you calculate Piston
Diameter?  I took a guess for both the above speakers, but don't
really know even what it is supposed to represent.

Anyway, Perfect Box gives you the 'best' vent frequency for a given
setup--but how do you convert this frequency into vent dimensions?

Thanks!

I picked up an Chrysler AM/FM digital stereo radio for next to nothing some time back,
and I've just now gotten around to playing with it. 

There are two cryptic connectors on the back of the radio: one has 8 pins, the other
has 6 (I think, this is from memory). The pins are in a inline, keyed connnector that
I've not seen before. 

Unlike Delco radios, there is no pinout diagram on the radio itself. I've managed to
get the dial lite to come on, but not much else. I really don't feel like randomly
hooking it up until it's either fried or works. 

Any suggestions where I might find the pinouts? Information this specific isn't found
in your usual car repair manuals.

     I am seeking opinions from experienced installers regarding
round vs. oval speakers.

     I am thinking of buying raw speakers from Madisound and either
making my own "plate" type speakers with a 6-1/2 inch woofer and some
kind of dome tweeter, or else just buying a pair of Madisound/Audax
coaxials, e.g. 6-1/2 inch model 6102/Audax. Total cost would be in
the $80 to $100 range for the pair.

     Has anyone compared the sound of this kind of setup to widely
sold 6x9's in this price range, e.g. Pioneers or Kenwoods?

     This will be a modest installation in a 1980 Le Mans: The head
unit will be a "high power" Kenwood or Sherwood, with an honest 12W
RMS into 4 ohms, per channel. Yes, TWELVE Watts or so. Assume no
outboard amp for now. I'm looking for clean bass and smooth frequency
response, NOT trying to get >100 dB at < 100 Hz. These speakers will
go into the rear deck, with a pair of 3-1/2 inchers in the stock location
up front, probably Pioneer TS-879 coaxials.

I own a 1990 Acura Integra, and the front doors's factory grills can be
fitted with 5.25" speakers;  the rear deck can be fitted with 6.5" speakers.
The bottom of the front seats have appro. 8"x11"x2" spaces, enough for a

Precisely.  I too, bought a unit based on the name ALPINE.  The unit is
exactly one year old and has been treated with great care (cleaning
heads, capstans, pinch rollers, etc.).  However, the tape deck is now
completely useless as it simply auto-reverses back and forth, back and
forth between tape sides.  The inside is completely clean; no hair, no
goop.  There's no reason for this to happen that I can see.

Y'know, it's funny, but I didn't want an auto-reverse deck for just this
reason (I had a similar problem, to much lesser degree, on a low-end
Blaupunkt unit, which I can excuse).  By the way, the tapes are not
warped, they are in some cases brand new, it dosen't seem to matter.

Now, I'm faced with sending it out for repair (and being without tunes
for a month or more, which for me is not an acceptable option), or
buying a new unit.  This time, I'm thinking about a CD unit.

More on that issue in a seperate post...

Now you tell me.  I just had my windows tinted Monday. :)  Actually, i 
don't think the fact that my windows are now tinted will make any difference
at all. I don't think that my tinted windows will draw any more attention
than my:

	- stock BBS wheels and low profile tires
	- hole in the dash because of my pullout

			or 

	- the fact that my car is a VW Jetta (with the infamous
	  triangle shaped rear window) which theives just love to
	  break into...sometimes just for practice :)

Anyway, i have a good alarm, i remove the head unit, i park in well traveled
areas, i use a club, and although i don't want the worse to happen, i refuse
to let scum sucking thieves prevent me from enjoying my car.

Besides tinted windows look cool. ;^)
