hey guys i am trying to install a parrot ck3100 in my 03 ls430 with nav and mark lev, i have the quick connect harness for the parrot but i still have to tap into the speaker wires by bypassing the amp i believe, the problem is i cannot find the amplifier, or any speaker wire behind the radio, did anyone do this install that can help me? does anyone know where the amplifier is? does any one know what the wiring colors from the amp to the speaker? can anyone help?
