help...i am in the middle of swapping my stereo from one car to another. i have put the original h/u back into my commodore but it has been modified for RCA leads so i can run my amps. my original pioneer h/u never had any problems but as soon as i swapped h/u i get buzzing thru my rear speakers with the car running.....any hints would be appreciated

First you need to locate exactly where the noise is entering the system.

Then you can try and fix the specific problem, ie if it is a headunit grounding problem, then you need to fix the grounds etc

If in doubt, do a search and then ask questions!

i have checked all connections and they are all ok...the speakers i am using are holden caprice speakers which are custom made to fit on the parcel shelf. it incorporates a subby and tweeters. the buzzing is coming through the tweeters as when i disconnect them the buzzing stops but the subby works fine....

This is just a hunch, but its possible the head unit is getting a earth loop thru the antenea earth. Its a problem I have encountered once on another car where all speakers where run from amps except for the rears which where run from the head unit.
its pretty easy to test, either disconnect the antenea lead from the back of the head unit, or remove the antenea from the out side of the car, which ever is easier, but if its a holden caprice which I suspect, I think niether way is going to be easy so I suggest you pull the head unit and also try re earthing the head unit to a different location. Pick up a new earth point under the dash. don't use the same point as your amps.
