try redoing the grounds for your system. also check all the switches
on your amp. and settings for your head unit. the buzzing sound you
hear is often a case of a bad ground.. the system tries to find a
ground through other avenues ie the speakers or rca cables an causes
buzzing etc.. it is possible that there was soem damage to the system
when she moved things around ... wires touching things they shouldn't
is often a bad thing.
also... the inner part of the rca cable carries the positive signal
from the head unit.. the outer part carries the ground.. since there
is a ground already there.. it doesn't need it to make sound.. not
the correct way to hook things up though.. and can cause damage to the
system if left that way for an extended period
since it does work with the ipod.. your most likely correct in
assuming the trouble is elsewhere.. ( but not always always! )
is this a "simple" system? only a head unit an amp with speakers? or
are there more toys in the loop? if the latter.. try removing them for
testing. hopefully this is in vain and you have already solved to
trouble!

Ok, actually post install troubles. After installation, everything work
fine. Over the next month, some humming/noise developed, and was
occassionally quite bad. Then my wife stuffed the trunk full of stuff and
shoved the amp and sub-box to the side resulting in some wiring problems. I
replaced the rca cable from the head-unit to the amp and now there is no
sound when configured the same way as originally installed. BUT
- if I only plug one channel of the rca into the amplifer, there is sound
- if I directly connect an ipod to both channels of the amp, there is sound.
(so probably not an amp issue)
- if I just touch the post on the rca cable to the inside of the jack on the
amp, there is sound. Even though the outer part of the cable is not yet in
contact with the jack!
- in all cases, there is either no sound, or clear sound with no apparent
noise/buzzing
ideas?
