I have an 05 TL and a system that's been sitting in my basement for months because I'm too lazy to install it myself (and a bit nervous to mess something up).. and don't feel like paying $1k in labor. I have 2 6.5" Focal front speakers and a JL 10W6 with a Kenwood amp for the sub and a 4/1 Audison for the front pair. I want to use the factory deck and keep the navi speaking and voice command/bluetooth etc abilities.

I live in on Seacoast in NH near the ME border, but would be willing to travel for a professional install.

 

Try posting in the Regions forum, under New England. I'm not far from you but I am not very skilled with audio installs. Good luck.
