engine noise through speakers, any advice? Options

[NickJames]

I just recently upgraded my system to Kappa components and 2 ways in the rear. It is all powered through an 08 model infinity 4 channel amp. I get engine whine through my speakers with the volume low. when the music is up I dont reall hear. any way to get rid of it??

ground loop reducer/isolator.

But that dont always work, (not very well atleast)

Find a new ground. If nothing else, run a line off your batt. That'll delete all that unwanted noise.

ground loop

Yup, it is a ground loop problem. They can be rather tricky to resolve but search these forums for "ground loop" and you'll find a couple of threads with suggested approaches to resolving the problem.

it could be wat type of spark plugs you are using,does it change when u accelerate?

Ground loop is a condition where an unintended connection to ground is made through an interfering electrical conductor. Generally ground loop connection exists when an electrical system is connected through more than one way to the electrical ground.

When two or more devices are connected to a common ground through different paths, a ground loop occurs. Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment. To prevent ground loops, all signal grounds need to go to one common point and when two grounding points cannot be avoided, one side must isolate the signal and grounds from the other.

run you power wire and rca wires on opposite sides of the car.
also find a better ground.
