My 2010 Camry has a blown rear truck (not in the door) speaker and I am looking to replace the set with an aftermarket pair (GTO939 6"x9"). The stock JBL coax speakers are soldered to a 4 pin lead which snaps into a factory connector. My question is do I need to solder all 4 wires?
It appears that the factory speaker has separate connections for the the tweeter and woofer. The thing to determine is if the woofer output is full range, or if it has a low pass filter. hopefully, it is full range as that is what you'll need to use.
