I have infinity speakers, pretty new. I realized a few weeks ago that my rear left speaker went out, so I took it back to best buy for them to fix it. They did. Then a few days later, I noticed this weird noise coming from the speakers (cant tell what one)

It sounds like a mini supercharger, a whine noise. When I press the gas, it gets louder.


Any idea whats wrong?

 

Someone else just had the same problem.

 

not grounded propely by the sounds of it

 

^ link?

 

I have the same prob. I installed a new headunit and had to install a inerface module because of the onstar and all the safty features go thru. the stock radio and when I put in the new head unit you lose all those features but now I get alot of fuzzy and that noise thru. the speakers like a mini supercharger and same thing when i press on gas its louder. Have you installed a interface module? I think thats why my speakers make that odd noise now because it never sounded like that until I had to put in the module for the new head unit.

 

I got everything done at best buy, so its all covered.
I have the stock head unit.

 

I have to find it

 

called engine noise... do you have an amplifier on your highs?

engine noise. upgrade your ground

 

not necessarily... most of the time it an rca

 

Got a amp on the speakers, and the amp that powers my sub.

 

ive got the same problem, ground loop isolators are suppose to help but ive got 2, one for each rca connected to my 4 channel amp and my rear speakers still whine loud as hell...


im thinking i might just have to order some super nice shielded rca cables to fix the problem

its because of all the power wires running through the car, the rca cables pick up this noise and send it to your amp

 

its a ground loop as everyone is saying. could be a number of things

 

Well, they better fix it, becouse its under warrenty from them.

I'll be going to best buy this week.

 

let me know if they just reroute the wires or throw in a ground loop isolator...

although i think they will try to reroute it because GLI's are about 20 a piece

 

^ allright. Prob be going tommorrow, if it doesnt rain.

 

make sure your rcas arent near the power wires... that will fix it

 

Take your door apart, its not hard to do.
Check and make sure your speakers are not getting wet

 

i have the same problem with my car, could it be because i have a iff H/U with the stock amp still, and it doesnt create enough of a load and dumps the excess power to ground making the loop?
