Engine noise coming through speakers
I have had my components installed for a little while and I am getting engine noise interference into the speakers. It is a whine that gets higher frequency as I rev the engine. It is most apparent when in bluetooth mode and not talking to anyone on the phone. The head unit has been extensively grounded and the RCA cables are not near the power supply wire are there any suggestions you guys have for getting rid of it?

check ALL of your grounds, make sure they are making contact to bare metal, sand any paint off of the area around the ground connection, and make sure you have a tight snug connection in the ground. if the problem persists, you may have to invest in a ground loop isolater.
also, this is the fs section

why did you not use the factory ground wire? that would have been a known good ground. and like stated above, check the ground on your amp. if the noise isnt coming from the HU ground, then that is the next most likely source.
if all else fails, and it does happen in some cases that you cant get rid of a ground loop issue, a ground loop isolator is a device that can remove or minimize the ground looping issue that you are experiencing.

this was happening to me w/ my system about 10yrs ago in my gran prix, did everything possible including taking stereo out of car and hooking it all up, still engine noise, after filters and everything, long story short it was the hu messing it up the whole time, new hu worked perfectly

hmmm i have a premier p980bt could it be the HU I had the hu with the stock speakers before i had the components and never had any issues with this type of noise. Could it be because I now have better quality speakers it is becoming more apparent?

and doeskies, it would have nothing to do with the speakers. you would be experiencing this problem regaurdless of how good or bad the speakers are . it is an inductance issue because of bad grounding. with the ground being bad(probably too much resistance in the line), and remember again that power comes from ground in this case, it is not getting sufficient power, and is getting an interference inducted into the system. this interference is reproduced throughout the system, and comes out in the end through the signal being sent to your speakers.
did you get around to checking your amplifier ground? or fixing your HU ground?

Also if stock speaker didn't pick it up and the new one did, that would tell me that the new ones are better and more sensitive to sound. If that not the case, then there would be no way in hell that people would buy better speakers.
Not everything comes out one hundred percent from a company.
I am not saying to not do what other have suggested, by all means they are right. I would check the deck out also.

that would tell me that there was an install issue, not an issue with the speakers... speakers are (for lack of a better term) very dumb, they get a signal, they turn that electrical signal into an audible signal. if there is interference in the line, it is going to produce that audibly no matter how good or bad the speaker is. if you installed speakers and picked up a ground loop, it sounds to me like a poor connection was made somewhere that allowed the interference to be picked up.

Keep us posted on what happens. It would be interesting to see what fixed it.
