I just noticed some engind noise today that was not there before. Last night I re-positioned my amps, so that now they are right next to each other, side by side. They are close, so that they are nearly touching, can this be a cause of the engine noise?
The RCA's and power/ground wires are not next to eachother, and this engine noise only started today after I simply re-positioned the amps... any clues?

I didnt change any ground points they in the same location, the 2 amps are grounded at the same location. All I did was move them. Posts: 278 | From: USA | Registered: Dec 2002

you might wanna make sure your ground points are clean from all paint surfaces and tight.

if there's one thing in the world I hate about installing car stereos it's tracing down an engine noise if you have one cause there's millions of things that can cause them. But if you didn't have it before I can only think of 3 that would be a problem.
1 just a ground wire getting shifted and not making good contact anymore. Wierder things have happened.
2 that when moving your amps you ended up moving wires as well and put an RCA or even a speaker wire next to a power or ground wire which can induce voltages. Try to avoid running RCA and power wires parallel. If they are Perpendicular you really don't have to worry about induced voltages.
3 this one is kind of a long shot. But it could be when you put your amps side by side that now your power supply side of one amp is next to the output side of the other amp and the power supply of one amp is causing the noise in the other. Also with this senario the power and rca imputs are usually on opposite sides of the amp. So when putting the amps next to each other you run back into problem #2.
And finally if nothing else they have rectifiers for RCA's that go in line and take the noise out. Or if the problem is further up sometimes you can run the ground of your head unit all the way back to the same place as the amps. It's a bit of work but it sometimes pays off in the end.
Hope you get it figured out
