[OT]:Need desperate stereo help! Long

[vince@performancecarstereo.com (Vince Royer)]

There could defenately be a problem with your speakers.  I'd say either one
of your speakers is shorting to ground (contact with metal)  or shorting out
period. A speaker can short out if the voice coil is partly melted.  If you
have a multimeter, use it to check the impedance across all of the speaker
leads. You should read about 4 ohms. The important thing is that the other
speaker of the same size and brand should read the same impedance.  To test
for shorting to ground, put your multimeter on continuity, put one wire to
ground, and touch ALL of the speaker wires with the other wire. None of them
should have continuity to ground.

Sometimes wires get cut into on their way into the door, which will
intermittently short it to ground.  If you've fried one of your tweeters, it
can intermittently short out. Either of these situations would cause your
deck to either shut down under a protection circuit, or melt because of the
lack of a protection circuit.

Good luck and let me know!

Im having a stereo issue that is driving me out of my mind. A few
weeks ago, I lost volume to all speakers in the car. I was still
getting power to the head unit and everything worked as normal,
just nothing was coming out of the speakers.

I originally thought it was a bad head unit, so I bought another
and it seemed to work, however a day later the same thing
happened, volume cutout but still had full power. So then I
determined that there was something wrong with the wiring and it
seemed to be located somewhere within the factory harness. so I
totally redid the wiring not using the factory harness at all. Ran
new power and speakers lines. Factory harness is now eliminated.
So I have a new head unit, new harness going in to the head unit,
all new speaker wiring, and new power wire going to a new power
source.

Everything has been working perfectly for the past few weeks now,
until last night when I turned on the car and once again, no
volume! It came back on but it turned off again on the way to work
today. I am so fed up, I dont know what else it can be. The only
thing I havent replaced are the speakers, can there be a problem
with them some how thats causing this. Any help would be greatly
appreciated.

P.S. This is a standard head unit, 4 speaker setup.
