Default beginner install troubles

Sorry, I wrote that in a haste. I will reread your original posting and see
if anyhting comes to mind I missed. Frankly, if you have already read our
FAQ, I probably won't have much to add as it has the most comprehensive
troubleshooting flow-chart.

Good luck,
MOSFET

Thanks - I did read the entirety of the faq before posting. Perhaps I'm
such a "newbie" that I couldn't even identify the appropriate trouble
shooting steps!

I appreciate your speedy response, however I wonder if perhaps I need to
re-word some of my message as it seems I was unable to appropriately
convey what I'd accomplished to this point.

For example, you suggest "start with taking your Mp3 player and using a
short set of RCA's, take it to the trunk and connect it directly to your
sub-amp." And in my original posting, I stated "if I directly connect an
ipod to both channels of the amp ..."

I'm having trouble figuring out what steps to take next in determining the
problem. Just one more clue ...

please?

OK, problems like this can seem overwhelming so you want to have a
troubleshooting "plan" so you can first identify the source of the
problem. Before I give you any advice, PLEASE go to:

http://www.mobileaudio.com/rac-faq/

This is the FAQ for this group that has been added to and mended for over
20 years. It is FILLED with usefull troubleshooting advice from
engineers and pioneers in the car audio industry. There is a TREMENDOUS
amount of knowledge that can be gained from that site.

Like I said, you first need to find the source of the problem so break it
down into small tests. For instance, start with taking your Mp3 player
and using a short set of RCA's, take it to the trunk and connect it
directly to your sub-amp. This will tell you a lot. Like if there is a
problem with the connection going from the dash to the back of the car
(bad cables).

If it still works poorly try using a different set of speakers coonected
directly to the sub amp using a short cable, like a small set of test
speakers YOU KNOW work. If the speakers seem to work fine then there is
a problem with your subwoofer connections.

Again, break this up into small tests you KNOW should work. Hopefully,
it is not a problem with your sub amp but I suspect it is a wiring issue
(these kind of problems usually are).

Again, use the website I gave you as there is a comprehensive
step-by-step troubleshooting guide for problems just such as yours. Good
luck. Let us know how it's going.

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?
