Hey all,

I've just had a noise start from the left rear sub speaker on my 2012 Conti GT. On any music, no matter the volume (even if turned to the very minimum) there is a noticeable distortion or rattle from the back corner of the car. It sounds almost as if its loose or some trim has come ajar or something. It cant be a blown speaker, as the distortion is there no matter the volume. It sounds more like an amplifier distortion or something. The only way to stop it is to completely hipass the bass using the tone EQ (its a Naim system).

Anyone come across this before?

 

Either an amp issue, or as you suggested, something simple has become loose. If you can access the wiring to the speaker, then disconnect and reconnect to a known good one, that will narrow things down.

 

Hello all.
So even at minimum volume it still has the distortion? There are a few symptoms of a blown speaker. Voice coils are tricky. Some take higher volume then others to hear. Balance it left to right, and try to get in the back seat and put your ear as close as you can to pin point it. My bet would be the speaker, seeing that it’s 8 yrs old. Try unplugging it like AJ advised. Might be a little less bass but you won’t have that rattle.

Heck if you have the Ross Tech software it should tell you. When I ran it on mines it told me my left front mid had a short in it. I recently changed all my speakers out and my left front mid wasn’t even hooked up. The previous owner had a lot of custom work done (In all honesty it was a freaking hack job) and they basically messed a lot of things up that I had to go in and repair.
