hiya net.  the accord is getting nearer to completion.  it's looking good,
stealth-wise, and sounding better all the time.  

i'd like to solicit comments from the net at large having to do with dsp.  i'm
considering a dsp box to give me a bit more 'spaciousness' inside the car.
the current sound is solid and tight, but lacking in presence.  

do you have/use a dsp in your car?  if so, i'd like to hear from you about
your experiences.  i've not had a chance to hear a dsp working in a vehicle.
and i'm not going to listen to the sales droids, even the one that i trust,
about dsp.  

if you have any dsp input, model, make, pricerange, performance, whatever,
please email me.  if there is sufficient interest, i'll post a summary.

the only dsp that i've seriously looked at was the clarion din-sized unit.

cheers,

Hiya, I have a 1240Q, and was wondering if it can be run 2 ohm.  It is
100 x 2 RMS in 4 ohm.  It has an internal cooling fan.  The manual and
box do not say that it is 2 ohm stable, so it probably isnt...
Thanks

I am looking for information on a _simple_, _relatively inexpensive_
remote-mountable head unit with built-in tuner that can be
blind-mounted.  I would like a removable control stalk that mounts on
the column and can be removed from the car when parking in high-theft
areas.

Please note:  I DO NOT require audiophile-quality equipment since I
cannot afford it by any means.  I don't particularly need to rattle
windows a block away since this system will be put into a car my wife
and I will be sharing, and I don't need 25Hz-40KHz response.
Something with a halfway-decent sound with inexpensive speakers will
be fine.  All I need is this certain head unit which I am not even
sure exists.

I can install anything you suggest, so don't worry about schematics.
I do need aux. inputs for a CD changer and maybe front-panel inputs,
and I will be installing headphone outlets as well as speakers.  I
have the rest of the system pretty much designed; I just need this one

        Hello netland,


        I want to add an amp and 2  12's. The amp I'm looking for should 
        put out 150x2 (4 ohm) up to 200x2 (4 ohm) RMS.

     Yes, I have heard about this about 3 years ago when the new style
GM pickups came out.  Apparently, the amp is built into the deck and can
be activated by 'pressing a few buttons'.  A friend of mine apparently
knows (or knew) how to do it, but it wouldn't say.  I don't have a GM
pickup, but it would be interesting to know.

Hi,

I just installed a Pioneer DEH-M980 in my car this weekend and everything
is working great except for the FM reception.  Reception is not terrible,
but it isn't great either.  (I'm getting static on some of the stations
that my stock unit picked up fine.)  What I can do to improve the reception
on my deck (ie: Clean the antenna, get a new antenna, tune the deck, ...)?
Any suggestions would be appreciated.

The head unit is installed in a '90 Integra GS 3-dr (stock unit taken out
is a Pioneer KEH-6231).  Only the deck was changed and everything else is
stock (antenna, coax, etc.).

Thanks,

Organization: Environmental Research Institute of Michigan, Ann Arbor, Michigan

Greetings!

I'm considering buying a Kenwood KRC940 or Alpine 7525, AM/FM Cassette
unit.  I've been out of the car audio market for a few years, and would
appreciate any comments on these units (or others I might have over-
looked).

Basically, I have $500 to $600 to spend, want Dolby C, some fancy cassette
features (play radio during tape winds, blank skip, etc), and CD controls
(no CD unit planned, but I want the option), and at least 12 presets.

For the Kenwood KRC940, I've got a quote for $549 installed (lists for $699).
For the Alpine 7525, the quote is $549 NOT installed (lists for $599).

These two units have almost identical features at the same price.  Each is
from a different store that does not sell the other, and of course each
salesman is telling me the other is no good.  Does anyone see anything major
that I'm overlooking?  Does it seem reasonable to choose between these two?

What about other units, such as the Pioneer KEX-M850?  It's in the same
category (features/price), but I rejected it because it would need an amp,
and also because I don't know anything about Pioneer.

Thanks for your time!

Are they overpriced and overrated?

Hello netlanders,

I have a question that may have been covered before (sorry) but am a
bit confused about. There are many types of subwoofer enclosures
out there with many different names. I understand the difference between
a sealed and ported enclosure but what about 6th-order, 5th-order, etc.

I am planning on building one of these boxes in the near future but space
is limited. I have access to wood working tools and I believe I have the
ability to build a good box but what type is best?

I plan to buy an Orion 10" XTRDVC sub. The dealer recommended a dual
reflex box (a ported box on the front and on the back of sub). What are the
advantages and disadvantages of this type of enclosure.

Please explain good and bad points of these enclosures. Also, I am still
up for ideas on other subs to consider (Must need small box, the dual
reflex can be built with only ~1.5 ft^3)

Any advice on speaker, box, or design preference is greatly appreciated.

Hello all,

I'm sorry if this has been covered recently but I have some questions
about speaker box fill (polyfill).

I've heard that it can be used to increase the apparent size of a sub
box. I have limited space and am wondering if polyfill would be useful.
I have a couple of questions:

1. How much does speaker fill increase the apparent size of the box? 10%? 20%?

2. Can it be used with ported enclosures or just sealed enclosures?

3. How much of it do you use? Do you fill the box completely?

If there is a great response I will summarize to the net.

Any help is greatly appreciated.

I've located some woofers that I'm interested in, but they have no specs,
so I was hoping somebody could look them up and give me some specs, or some
off the cuff general knowledge about them.

Here's what I know:

10" Subwoofer, dual voice coil
Poly cone/foam suspension
64oz magnet
200 Watts (peak?)

They are manufactured by Carbonneau Loudspeakers in West Michigan and 
the box is labeled: "Perfect Interface, 6-10in STS-108DVC"

The retailer claims that they were used in Rockford Fosgate boxes, but they
appear new.  An Ohmmeter measured 6.9 ohms and 7 ohms across each of the
coils.  Does this automatically mean that they are 8 ohm rated?  I found this
odd because I expected Rockford stuff to be 4 ohm for car.

I'm looking for Thiel-Small parameters, general reputation of Carbonneau, or
anything else on these woofers.  What is a normal price for these?

Thanks alot...

Turbulence basics say that you cannot have wistling without turbulent flow.
Sharp edges, discontinuities are just the thing to make a flow turbulent.
Any way to remove the edges in the flow will also do away with the whistling.

Pretty funny though, whenever I ever see a bad dealership, I think of Sound
of Market II (I would have hated to see the first one)

George,
        Could you please relay the following to your answer.  Also
please suggest technical papers on port tuning available from JBL.
Thanks in advance...


        Whistling port!  Air particle velocity must be well above 2% of
Mach!  Definetly bad - a good indication of detuning.  Your probably
running at a much higher Hemholtz than the port has been tuned.

I would suggest redesinging the port so that it is more efficient.  A
good base for determining port size would be to start at one third the
diameter of the driver and up.  It is not uncommon to see port sizes up
to one half and above the diameter of the driver.  The air friction that
is present in the port, the less the turbulence, the less the whistle.

When you are recalculating the box's Hemholtz and port, try to keep air
particle vvelocity in the port to 1% and under.

Good Luck....                  Chad Thomas

I need an amp for my lonely Kicker C-8. Amp should put out about 70 Watts in
bridged mono. Should be inexpencive.
I'd get a new one, but as you might have guessed can't afford it right now.
Anybody wants to part with their amp?
Any advice? What to avoid?

Please email to mns6569@ritvax.isc.rit.edu
or call 716-244-7914
Thanks. MIke.S
