el mounting points. It can be helpful to tuck the tweeter wiring
into the adhesive of the foam door liner.
64. MOUNT MIDRANGE/TWEETER CROSSOVER (STEP 1)
Route the midrange/tweeter harness to the lower rear of the door
panel. Connect to the midrange/tweeter crossover and do a test
t of the crossover (1). The crossover should t completely within
