Yep thats the sum of it. The original remote on lead was intergrated into an
RCA, I replaced it with the dedicated one that came with my amp wiring kit
and no more noise... needless to say I was pretty happy - a no cost complete
solution =)

This was fixed by replacing the remote turn on lead with a new one
right? I have a noise issue that different grounding schemes have not
resolved, and I am about to place a relay in the chain for the remote
turn on lead.

must admit I'd like to get rid of the noise by 'natural means' first...
worst comes to worst I may try a ground loop isolator but it'll probably
a
last resort. Thanks for the tip anyway. I must mention that radioshack
isn't
the most common of brands over here (they are distributed through
another
retail chain) so I may have trouble even finding one.

Try a RadioShack ground loop isolater ($15) between the head unit and
the
amp to see if things quiet down. Try to be sure none of the RCA outer
shells are touching ground anywhere.
Good luck

Hi all - I vowed I wouldn't join the masses and post a question to
help
with
a noise problem - but I've got one, and my reading and attempts so
far
haven't fixed it so...
I recently installed a new amp (Boss Audio), subs (Pioneer 10") and
head-unit (Panasonic CQ-DFX572 - I think its an international model
and
may
be called something different in other countries) in my Commodore
(for
you
aussies). Since the install my front speakers (Kenwood 6") have
exhibited
an
audiable buzzz. Its not particularly loud, its only noticable during
silent
parts of the music. It goes away if I remove the either both the
subwoofer
RCAs or both the front speaker RCAs from my amp (only subs and
fronts
are
running off the amp). It doesn't change when the car is on or off or
with
engine rpm. It does change when I adjust the gain to the front
speakers
on
the amp. It doesn't change much when the volume on the head unit is
changed.
Its on right from when the head unit switches on to when its turned
off.
As to my install, I've got my speaker wires running up under the
roof
trim,
my amp power wire running in the lower door foot trim and my RCAs
running
down the center hump. I've checked my ground point, cleaned it back
to
bright shiny metal, installed a washer to help apply pressure.
I'm pretty sure its not the speakers because they were fine before
the
install and are fine when the subwoofer RCAs are pulled. My only
ideas
how
to fix it now are to completely relocate the gound point. Its
currently
into
body metal on the front of the trunk - for those familiar with
commodores
its into the seat support metal in the sedan. I could probably move
it
lower
down so it was directly onto frame material but I'm not sure it
would
help
signifcantly - its already on a well integrated piece of steel.
Another
idea
would be to start moving cables around... but where? - everything it
as
far
away as I can see practical. Finally my last option I guess is to
check
the
ground on the head unit - its currently to the factory ground wire -
I
assumed this would be sufficient.
So any ideas people? - is it likely that it could be a problem with
the
head
unit? The head unit has 6 pre-outs - 2 front, 2 rear, 2 subs. I'm
using
the
2 front and the 2 subs with the rear speakers being driven off the
headunit
preamp. It it possible it could be the amp? I wouldn't have thought
so
since
it seems capable of making noise free music under some
circumstances.
Anyway, any help would be greatly appriciated - especially if it
would
save
me the hassle of ripping stuff out again. Any body interested in my
install
so far can check out
