I need to know if there is any way of putting my system i had removed from my 2nd gen TL into my 3rd gen 05 TL non navi, i have an alpine IVA-W505 double din and clairion head rest units plus alpine type R door speakers and alpine type X sub with amp ?

 

yes... with some custom work done at the headunit area...

Plus you'll lose the Bluetooth , HFL...

 

is there pre amp out on the factory deck?

 

not really, there is a signal, but you will need a line driver to bring it back up so the amps can actually do something. the 5.1 signal from the TL's HU is pretty good, I would avoid swaping HU's as much as possible becuase:
1. You loose your HFL
2. The center stack will look horrible
3. Half the upper screen will never turn on
4. It won't flow with the car
5. No real advantages over stock

You can get some LOC's, hook them up after the factory amp, connect them to your amp and then speakers.

 

thanks i was thinking to do that instead of changing the deck i'll probably just sell the other stuff n keep the speakers
