Hey guys. I recently added a couple of subs and a amp. I tapped into the factory sub wires for my line out, but was thinking I may get a better signal before the factory amp. I am just not sure where it is? I have a 2001 gs430 with navi nonML. Thanks for any input.

 

behind glove compartment on the right side. get a wiring diagram online to figure out which wires will be the sub wires. I believe they were brown in my year (2005)

 

Thank you ! I actually got a offer on the car I couldn't pass up so never even got a chance to finish the wiring. Oh well. Thanks for the reply though !
