hey guys, i just bought my first car ever today which is an 08 tl with the navi system and i need some help/ideas on how to install
my new sound system. ill start out by saying that i know how to install head units speakers subs amps and caps and that i already
have all of the components to start the build. my only problem is that ive never dealth with an installation while keeping the stock
head-unit. the equipment i have is a 1500 peak watt amp for my 2 12inch mtx's, 4 6.5 speakers, and a 500 watt rms 4channel amplifier
for my speakers, aswell as all of the wiring. the main thing i need help with is how to get the signal from my head unit to my sub amp, same goes for my speaker amp

I'm using the AudioControl LCQ-1 in my 08 TL with navigation. You run one side into your factory amp that is in the front right kick panel and your amps into the other side. This is what I did. https://acurazine.com/forums/3g-tl-audio-bluetooth-electronics-navigation-94/new-jl-audio-system-pics-865893/

 

so my understanding is that ill take the line out converter and connect the negative and positive to my speakers neg and posi leads, then connect the remote wire to a fuse or something and i should be good to go once i connect the rcas to the amp?

 

You say...
But your asking...

People are not going to hold your hand for this. Did you even do your own research? You just got "your first car ever" and you probably need to spend some time learning it before you come back posting your problems
