if you up grade the speaker in the tl and add a amp will that disconnet the voice to the navy.will it still mute the speaker and talk.if there anyone out there that know what to do please let me know and what would you recomend

 

no, yes, do it.

 

do i hve to have the factory aMP DISCONNETED or the navi mutes throught the headunit.trying to figure out the best way to do this 1amp or 2amp

 

I think you need to keep the OEM amp.........unless you wire up the new amp to do all the OEM functions.

 

All functions happen at the HU. The amp is just an amp nothing more. Keep the oem amp, add LOCs between the OEM amp and new amp(s).

 

Kyle,
I like your answers, short sweet and to the point.
