Engine noise thru speakers

Just recently my lude has developed an issue where you can hear a high pitched whine out of the speakers which goes up and down with the revs, but it only does it sometimes. Some people have told me that it could be a dodgey earth, and some people have told me it might be a faulty engine noise suppressor. Do our cars have them standard? Where would i find such a thing? I looked everywhere under the hood and couldn't find one. I'm nearly confident that its not an earth either because i did the install myself and surely i'd be having other problems apart from an annoying squeal. Any insight anyone??

I would say that it is a bad Ground, do you have an amp and subs or just an aftermarket head unit.

Do you have an aftermarket head unit installed? there is some sort of interference from bad wiring. Pull your head unit out and check it...

what type of head unit are you running? where is your ground placed? what gauge wire you running from the battery to amp, and check the fuses.. most of the time.. it's the ground between the head unit..or the battery to the aftermarket sub-amp.

I have an aftermarket headunit and 4ch amp driving all the speakers. No sub at the moment. The headunit is brand new and there was no problem with it for at least a couple of months after the install. It seems strange that it started all of a sudden without any of the system being changed. Oh yeah, we call ground earth down here.

Oh yeah, Its all kenwood equipment. I cant exactly remember but i think i'm running 4 guage to a power distribution block in the back, then 8 guage to the amp. The ground to the amp is 8 guage too but the headunit is run off the original ground under the dash.

Check to see if any of your sparkplug wires have a break in them. The actual wire for the spark to run through is about the size of a hair. The reason that plug wires are so much thicker is because that tiny wire is surrounded by insulation. Not only does that insulation provide protection for that tiny wire, but it actually prevents us hearing our engines through our speakers. Its caused by RFI and EMI. Radio frequency interference, and electromagnetic interference. EMI can also send errounous signals to some other aftermarket engine management systems and other on board electronic devices. Its rare, but it can happen. If it werent for the insulation on plug wires, we wouldnt be able to listen to music. check that, if your wires are fine, idk what it coule be

I didn't know that, thanks. I'll check my plug wires. But in that case couldn't i be getting interference from any part of the ignition system?? ie coil, distributor, alternator etc?? They'd all be producing this 2k to 7.5k (at times) Hz frequency thats so troublesome wouldn't they??

Thats exactly right... make sure the power cable and the RCA cables dont run together.. Thats the main reason why ur having this problem.
