I want to add a subwoofer to the exisitng JBL Premium Sound system that came factory installed in my vehicle,and was wondering if anyone knew of a site with wiring diagrams of the JBL system that is installed in a 2002 Toyota Sequoia, so that i can hook up an aftermarket amp to the additional aftermarket sub.

ANY help will be greatly appreciated on this subject.

You can always use a line level converter that converts speaker sugnal into RCA and you won't have to tap into any other wires in the Toyota other than the rear speakers and an ignition turn on wire. These units are very inexpensive ..... about $ 25 - $ 40 depending where you live.
