so i installed the amp and sub just like i did in the old tl into my new 08 tls and when i turn the car on the sub just starts blairing for no reason and as soon as i push in the clutch and rev the car it goes away once the engine settles the base comes blaring back

 

there is a connection that you have to remove in the headliner light area . some green clip . read about it here. it sounds like that

 

so where am i suppose to be clicking to see it?

 

i had the same problem i took it to 3 professional shop and still cant get it please let me know what needs to b done

 

disconnect the noise cancellation microphones?

 

thats it take the rear light down and 3rd brake light cover down.....theres a green plug right next to it and ur in the clear the noise cancellation is gone.

 

thanks as i will try this saturday

 

r u sure that works for 08

 

^yeah, it should be the active noise cancellation interferring

 

that was definitely the problem appreciate the answer!

 

glad we can help

 

I also am putting in my system soon, So this active noise cancellation is it similar to that bose technology where it plays the opposite of the noise coming in?

The guys at the local stereo shops sound like the ones you went to, they heard of a technology that adjusts sound output with speed, but not the noise cancellation.

 

my car is a automatic and wen i rev it like pearlite tl said it goes away ..but it will come back and then wen i open up my door it goes away again ..i drove with my door just cracked open b4 and it doesnt do it......now do i need to buy anything or can u guys break it down nice n easy to me on how its done and wat i need cuz i was a test dummy at stereo shops and i dont wanna b the test dummy ...i can do it all my self if u guys can explain how its done please

 

its been posted 4 times......read it 400 times over because if u cant understand whats written.... print it and bring it to the shop for them to do...... someone close this up please.
