i search and could not find the exact answer that i wanted but this is my question

i have a good sound music in my other which is for sale (mitsubishi eclipse 01), i want to install the sound system in my tl. i haven't done it yet cause i'm scare that i might loose the voice comand, the navi voice command, or bluetooth when someone call. usually you press the BT button to make a call, the music stop and only the bluetooth calling works. also when using the nav and playing sound, when is time to announce a street turn etc the navi turns off the front speakers and leave the back speaker with the music i was listening.

will i loose all that installing aftermark amp with speakers and a sub.

if that so i'll rather sell my equipments

 

tap after the factory amp and you won't loose anything. You will need a high-low converter to reduce the voltage of the signal unless your amp has high level inputs.

 

do you have to remove the passenger sit to remove the stock amp, or leave the stock amp and only run the audio cable to the rear aftermark amp?

 

If you use a high-low converter, you'll leave the factory amp alone. I tapped in to the factory subwoofer, those + and - cables will go into the converter; from the converter, they'll go into the aftermarket amp as RCA's. The best part is, you'll still have factory controls of your aftermarket sub.

 

leave the front center channel on the factory amp to retain the voice prompts if you don't have enough channels with your replacement amp(s).

 

if i were to use a 5-channel amp for the fronts/rears/and center, will i still retain the hfl and nav if i tap before the amp?
