Problems with sound system

[Winn]

1) its pissing me off like. before starting my car the sound is fine but as soon as i start my car the buzzing noise starts. i have to turn my music up so i cant here it. the buzzing goes higher pitched the higher the revs are too!! whats going on like!!!

2) Just for advise what would you do if you have sub amp n 6*9's.

At the mo ive got the sub and 6*9's to my amp. but would it be better just have to the sub on the amp n leave the 6*9's as connected without the amp.

HOW DO I GET RID OF THE BUZZING NOISE!!
thanks

not a sparkie, but could be a bad earth, and i dunno if altenators have suppressors on them these days?

also, running signal cables too close to power cables ive heard is bad,

im sure someone has some better ideas

try running a new power cable to it direct from the battery and if it goes away with that then you know you have a problem with the live wire. like wise with the negative and try and fault find like that!

IT will be a bad earth or interferance from a power cable, also make sure you have a decent gauge cable for your earth.

With regards to your amp n'sub it really does depend on the rating of the amp.

yeah as above it will be a bad earth,

as boss said you can try running the cables down different sides of the car, i.e. the power down one side and the audio down the other I have heard various rumours on this as in yes it works and no its just a mith.

Run the power +ve direct to the battery, Use an earth (chassis) as close to the source as you can (do not run direct to the battery).
Power cables can cause interference into speaker wire- so do not run them close together.
This is not a myth - I had this problem on a MR2 where the battery is in the front & the engine in ther rear- meaning all power cables went down the sides - this did cause whining, so I had to run the speaker wires down the centre.

also as i found out, try not to have too much speaker cable,, only run what you need so you havent got a load coiled up in the boot etc etc the more cable laying around the more ther is to pick up the interferance
