Hi everyone, im new to this forum but I have a slight issue. I have recently installed my amp and sub into my 07 tls, and i am getting engine feedback through the sub. But here is the weird thing it only gets feedback when the engine rpms are at idle till about 1800 rpms, then it is gone. Also at idle while it still is getting feedback, if i open any of the doors on the car it goes away??? I have tried to relocate my ground and line level converter and still the same problem. I also have tried to search the forum to see if there was any post about this same problem but could not find anything. I am just trying to eliminate feedback, please help???

 

I'm subscribing to this thread, I've got a very similar problem, but the feed back I hear is coming from the speakers. Sometimes goes away once the car warms up, but man its annoying as hell.

 

sounds like you did not disconnect the noise canceling mic/system when you did the new sub amp.

 

You are correct sir.

 

x3...this is the problem for sure!

 

thanks, but how do u disconnect the noise canceling system???

 

so you know, there are multiple threads dealing with this exact issue...maybe take a look in the garage section...here is one example

but if i remember correctly i believe you have to disconnect something in or around the rear seat ceiling light.

 

hey thanks guys!!!! i just disconnected the mic in the rear of the car and the noise is gone!! i appreciate all the info!

 

hey guys, i have a 2006 and i was all happy to take off my rear dome light only to find that i have no rear mic. so do i have to get ground loop filters installed? i have been having to deal with this whining noise for over two weeks.

 

Bout to do an install in mine didnt know there was a noise canceling mic, good to know now!

 

there are 2 actually, on in the rear headliner and one in the sunroof switch assembly

 

no noise cancellation in the 06, only the TL-S not sure about your question though...sorry

 

well after sifting through everything like a hungry hobo. toasters seems to have said it best when he said he just installed ground loop filters and the annoying noise is gone. i guess thats the only answer
