Trouble from ground distribution block

I have alot of engine noise coming from my speakers.  I accidentaly orderd a fused distribution block for my ground  and I have been using that could that be the cause of my trouble.

possibly, did you run your power wires close to your rca's.? how long is your ground?blah blah blah blah

my ground is only about 12-15 inches long

do you have alot of engine noise from subs? from internal speakers? both?    are thier amps on both internals and subs?    2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

I just have alot of engine noise from the internal speakers the subs sound great.  There is a sound from the subs when i trun my head lights on and off but just for that split secound and thats it.  The internals are noisy constantly

I am running four gauge to the dist box and 8 out and I ran the power on the opposite side of the car

I jsut read this from http://www.bcae1.com/ thought it might apply: "When making any connections in your audio system, remove all power from the system. One reason (there are others) is that the shield of the RCA connectors is connected to chassis ground in at least one audio component (almost always grounded in the head unit). If, at any time, the shield is allowed to come in contact with any power source, the component with the grounded shield connection will be instantly (INSTANTLY) INSTANTLY damaged (Oh, did I say instantly damaged?). This is one of the most common causes of loud engine noise and it is VERY common."

Try a capacitor. It need not be something huge meant to help with power problems. Even a few mF should help somewhat. Just make sure the voltage rating is at least 16V, preferrably 20+.2009 Pontiac G8 in planning stage

The fused distro block has nothing to do with this. List the equipment and the vehicle year,make, model. What you have is more than likely a difference in ground potentials. Any chance that you have a Pioneer head unit?Top Secret, I can tell you but then my wife will kill me.
