Okay I just installed a pioneer avh 4300dvd in my new 09 Honda Civic Si.Everything powers up fine and works even the video bypass.My problem is when the key is turned one click all speakers are fine, but when I turn the car over I have a noise coming from the right side speakers.Its only the right side like it has something to do with the rca outputs.Is this a pico fuse problem? Please help guys annoying as hell.

piico fuse problem yields nearly no .. or zero output.

the key isn't the issue, it's probably vibration as a result of your engine revolutions.

if it was in both sides, I'd look into other things but since it's not, it's probably you RCAs.

When I say turn the key over Im not talking about turning the car on just the last click you have ! !! !!! clicks.With the car sitting I turn the key to ! it plays fine But when I actually turn it over to where it would be on it has the noise.

when you go to that position either the fuel pump, blower motor or some electrical motor is running and sending noise through the ground circuit. Either move your amp ground or try grounding your RCA's...

guys, near as I can tell. he has cut RCAs off and connected them to his speaker leads which go to his factory amp.


The fuel pump/heater fan noise is probably induced and will not go away until he either gets rid of the factory amp or finds another way to connect it.

dude.
cutting RCAs and connecting them to speaker wire is not cool.

move the ground from the headunit is only ground I can move.The amp ground is under driver seat.I understand grounding the rcas but why does it only bother the right side channels

im not totally sure, i'd suggest getting a line output converter and switching the RCA ends to hi level speaker... like other people have said it makes a lot of sense to think that the RCA's are picking up some electrical signal from the car, and because the RCA's are just bare and not insulated, im sure that'd make it much more likely to pick up EMF, or even current through contact..
