Hello all, I have a 04 tl with navi that i just bought and i was wondering what the sub control does.. I really dont hear much of a difference when its up??? Does this TL have a sub some where or is it a bass setting for the mids?

 

The TL does have a sub, and there are seperate controls for bass volume and subwoofer volume.

 

i assume the sub is above the panel in the trunk?? The bass has its own volume.. The setting on the navi isnt the volume for it???

 

Yes- the setting on the navi screen is the volume for the sub on the top of the trunk shelf. I think the problem you might be having is the type of music and the quality of the input. Sometimes I can't hear the difference at all when I adjust the sub volume but other times it's really obvious.

 

ok... i need to look at this "sub" Has anyone replaced it with an after market sub sych as jl or soemthing like that?? Was there a diff???

 

they have added them, but not totaly replaced them because it would be pretty hard to get it in there

 

Others have covered the bottom of the sub with dynamat or something similar and reported better sound.

 

yes...i agree, sometimes the sub just don't stand out much...
there was once i thought the sub was broken
