hmm weird electrical noise..

[KyleBechtold 5,000+ posts]

So I will start by saying the noise is engine whine.. yaya rca grounding w.e w.e...

Ok so I have three amps.. front speakers amp rear speakers amp sub amp..

the sub amp has its own remote directly to the h/u.. the rear speakers amp has a remote going to a switch which goes to the fronts remote..

now then.. if I have the rears switched off I get noise in the front speakers.. but when I switch the rears on I get the noise to them and no longer the front speakers.. I have tried rca grounding, moving/switching rcas, noise filters on the power line, noise filter on the rcas, the ground is directly to one of the rear batt.. none of this worked.. the only way to COMPLETELY get rid of the noise is to have the rear amp on with no speakers on it.. thats how it was for a while cause I didn't want the rears on all the time so I removed them.. Its a pod. easier than amp removal..

my thoughts.. there is noise some where on the remote line on the two speaker amps.. but why is it only in one of the two amps at a time.. do they make filters for remote lines?? any one have this issue..?

I don't think it sends noise to the sub amp but I don't think I could hear it if it could.. Its a HIGH pitch noise..

help.. please.. its decently loud.. and annoying

do you have any old videogame controllers? they have those little round bumps before it hits the console, pop one off and put it around your REM wires. its a ferrite magnet that will absorb emi. that should help, put it closer to the source. Im not sure if this will help 100% but its worth a try and it works for networking when we make long runs.

do you guys have a source for the magnets besides old controllers?
