Since i changed my header, i got problem with my sub. When the motor is running, i hear some parasites that increase whit the rpm. I checked every whire and every ground that i found on the car. But i found nothing ! Is there supposed to be a ground on the header ? I have tried everthing, change the rca, reroute them , install a noise filter and nothing has changed !

look right below the header, there should be a small silver cylinder bolted to the block right below the head. make sure you didnt break the wire going into it. that is there for noise supression as well.

otherwise I cant see how changing the header created noise in your stereo.

thats a very intersting one. do u have a diagram of all ur wiring and equipment names? you shouldnt have electrical noise from chaning a header, maybe its just regular vibrations that resonate in ur trunk?

I just wish my car was as fast as it was loud. people tell me i should use my sub to push it, it might go faster.

maybe your alternater is going

I have changed the little condensor on the motor, but i still have a problem. I Think that my amp is the problem. Because i put my home theater amp in the car to do some test and i had no more noise comming from the sub. I'll return the amp frist thing in the morning tomorow! I realy pissed about this , for the past two weeks i've been driving whitout music in the car.
I have a clarion dxz845mc head unit, a clarion pro audio 320w amp,a condenser and an aluminium 12inch eclipse sub.Just ennuf to get deaf and turn my seats in massage chair

just came to say that finally, after 3 weeks driving around in a strip car a redoing all the wirering, that my amp was the problem!
I went to the store today and came back whit a brand new amp and everthing works well !
Tanks for the help anyway!
