i no this sounds odd but does it sound like a supercharger whine becuase that means you power cable is interfeering(sp) with your rcs\speaker cables.

Dan

ever experienced this?

Its an urban myth, i.e, it never happens.

yes i had this in my mk3, i move the cables around and seemed to cure it

Dan

moving the cables may very well have solved it, but it is not because they were separated ;)

anything with power going through it ie power cables immit an energy field and can be picked up by rca`s depending on the sheilding on the rca`s. i used to find it was the cheapy rca`s that it happened on mostly and if it was to speakers like the rears or fronts. i never found it to do it with subs but thats not to say it wasnt happening  it just means it wasnt heard because of the different sounds that subs give compared to rear or front speakers. so i would run power and rca down seperate sides of the car make sure your earths are solid if all that fails change the rcas.

Power and RCA do sometimes interfere with each other, its always best practice to run them down seperate sides.

However i;ve done plenty of installs for people where cables have all gone down the same side and theres been no interference - depends on equipment and installation.

Best bet is to check that the grounds are nice and solid, make sure the surface you are grounding to is good and clean - no rust, corrosion or paint on there and then tighten the wires up.  If you have a multimeter i would also check the grounding to ensure that the resistance is low from amp to ground.

You can buy suppression kits that are supposed to elimate the noise, i've always found these totally useless, at best cutting the noise down but not eliminating it.

wampablo - got your pm, unfortunately i dont think i've made enough posts yet to be able to reply.

I dont work in the trade any more unfortunately so not sure if i'll be much use in getting you a job - ironically i'm now in recruitment.

Have you built a portfolio of previous projects up?  i would suggest this is your first step, if you can demonstrate to an installer that you have a good technical knowledge and a proven ability to install then im sure someone will give you a chance.
