Sub goes with beat of motor????Please Help

Hi all, I have intalled my sound system into my VR and i have just been listening to it when the car is turned off. Anyway i turned the car on and went to listen to some music then when my sub came on and before i put a song on the sub was making bass with the beat of my motor lol. Do i need to get some beefier RCA cables to stop interferance or do i have another problem?

Cheers!

are your RCA's running down the same side as your power

 

[bpottz]

yeah rca's are most likely picking up engine noise, if they are running down the same side as the power, run it on the other side

Well the RCA's are running down the middle and the power is running down the drivers side. But they meet at the back seat

What brand head unit? Are the speakers running from the head unit or an amp? Do they do it too?

Its a pioneer head unit basic model only about a year old. The speakers are connected to the head unit and no they don't do it they work fine its just the sub. When i rev the car the bass gets louder so it is in sinc with the motor.
