buzzing from speakers

[customnova]

if the car is turned on then the speakers do a buzzing noise and the pitch of the noise rises when i put some gas on, also the subs kind of punch when i use the electric windows or change the song, to me this doesnt seem right and its doin my head in now as its quite loud, does anyone have any ideas about what is happening?

Are the sepakers connect from ur head unit or a seperate amp?

my suba are connected to one amp and 4 speakers are connected to the other

if u got the power cable running along sode the RCA cable (left and right audio) this can sometimes cause interference apperently. i got mine right next to eachother though and have got no problems at all..

the buzzing noise is from the altanator (spelling!!!) to fix this you need a niose suppersor, there cheap and aviable from any car audio place, are both of ur amps earthed to the same place??
