Front dash tweeter is 4ohm and 2" , replaced with Alpine 4ohm speaker with custom mounting bracket ( use old tweeter as template ).
Front door speaker is 2ohm 6x9 , replaced with 2ohm jbl tri axle , easy fit , direct swap
Front dash tweeter and front door 6x9 are in parallel for total ohm of 1.33 ohms
Rear door is 2ohm 6 1/2 speaker , replaced with Kappa infinity ( cut old speaker out of factory bracket and fabricate to fit) works great or order an adapter
SOUNDS AWESOME! however I did add a 500 watt sub , tapping the signal off the rear door speaker wires behind the kick panel just before they go threw the rubber boot to the door
I used a speaker signal to low level converter with amp trigger for this and a 3 fared cap for the amp, next is a mediabridge 1502 for bluetooth and iphone connection
