engine sounds thru the sub

[tim-mania 10+ year member]

I have heard of this problem before, you can hear a high pitched whine through the sub that seems to be the sound of the engine, and it gets higher as you rev the engine higher, but with music on its not noticeable. People have told me that its from the amp. It's not a huge problem, its just annoying. Can it be fixed?

make sure your rca's are not by/running along any power source. also check your ground. make sure it tight and its a secure connection. (bare metal no rust/paint/fabric...) hope this helps!

THis could be the problem... Just run the rca's down one side of the car and the battery and remote downb the other side if it's not already and in the trunk make sure they are seperated

another possibility is that your power wire from your battery to your amp could be running to close to the alternator. you want to try and keep that at least 8-12 inches away from the alternator

guys forget about the RCAs & power wire voodoo-------- just start debugging by muting the amp

this solved my problem. how long is your ground wire? it should be 2-3ft. max

hey tim-mania any updates?

Hi,

It' could be your amp itself, tap all around the amp especially in the middle. Start lightly and work your way to a firm tap.......if you hear distinct changes in the noise (steady after the tap) then it probably is your circuit board inside the amp.

Or if you brought the amp to a lower impedence than it was designed for ( running two 4ohm subs on each channel bringing the total to 2ohms) than you probably damaged the power supply.........//content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif

But what the hell do I know........I'm just a thread writer......//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Well ignition noise we all have some. no simple way to shut it off completly but heres some things. make sure you have higher quality RCAs people are right, just any will work but not just any will sound good. see how high of a preamp you have on the head unit the lower the Voltage on it the more gain you turn it up the more noise you pick up. another thing is keeping the power and RCAs away from each othere. so i hope this helps good luck

lower voltage doesn't give you alternator whine
define "higher quality" RCAs ------- and why change them without knowing where the noise is coming from

why keep the RCAs away from the power wire?------don't say noise induction---- there isn't enough current to induct a noise that can be heard
