I have had some speaker interferance ever since I hooked up my main speakers to an amp. The noise gets high pitched when the rpms are higher. What can I do to fix this?? could this be caused my my MSD??

 

It could... my brother has interference in his truck that we've pretty much narrowed down to that. he's going to install that little noise filter they sell in Summit that speciffically for it, unless I con him out of it and just have him put a .5 Farad cap in the primary power wire, that should filter the noise out as well.

 

I have a 1 farad cap, and still noise.

 

did u run the power wire and the rca's down the opposite side of the car?

 

i briefly mounted a crossover over the gas tank on the driver side under the plastic pannel, i got alt whine, moved it and it cleared up.

 

I have suffered from the same problem.

I recently re-wired my whole system and ran the rca's(with twisted pair technology) down the center of the car, power on the passenger side and the speaker wires(which are highly unlikely to pick up noise due to the frequency level) on their respective sieds of the car. At this time I had my amp just sitting in the bottom of the t-top well, now it is mounted on my amp rack against the wall in the trunk and it began picking up interference again!!!

So I went down to wal-mart and grabbed some ground-loop isolators (made by schosche) for $12 ea and now my problem is gone again. I would suggest looking into using a ground loop isolator is re-routing the wires doesn't solve anything. Good Luck
