2003 TL, stock system

I have a 4 chl amp which I want to hookup. keep all existing components.

Will this be possible? will I be able to keep the stock sub working ( but not hooked up to the amp?

 

If you aren't replacing the deck, then no it will work still (assuming you are tapping the wiring instead of outright removing it.

The sub works on its own amp (in the back), signal is given to it via the pre-amp wires in the harness.

 

there should be a way this could be done, someone i know is running an aftermarket speaker amp with the stock navi head unit in his 3G TL, don't know how he had it done, but it is done

 

I am also very interested in adding an JL audio 4 channel amp and component speakers. I would rather leave the factory radio in place. Can this be done with good sound output? Do I need to use a sound processor the JL audio cleansweep unit? Is the amp behind the rear seat only powering the factory sub?

Also want to plug in a parrot blue tooth kit and adding an amp will save me from purchasing a specific wiring harness. any advice?

thanks

 

yea i want to know how do you run an amp after market amp with the factory hu? 99 tl with navi:-)

 

I would suggest replacing the head unit and speakers. The bose speakers are at best, 'ok', but it leave a lot to be desired. The car is very well insulated as is, but you may also think about dynamats.

 

ok i would replace the speakers cause i dont get the sound i want from them, but i want to keep in the factory hu cause of the factory navi. i want it to talk thru my speaker.

 

Holliewood you could go to your local car audio spot and get an adapter to hook up to your factory speakers that you can just jump the RCA's up to your amp from it. if you plan on changing out your speakers your still gonna be in the same situation, i believe the only way around it would be to change out the hu. from reading on here otha members are sayin you can keep the factory navi and swap out the hu and keep the voice dont quote me on which type of hu tho you would have to look into it
