So I bought new Pioneer speakers that Crutchfield recommended for the lower drivers door on my 2012 Explorer XLT. Through crutchfield, I bought the wiring harness and mounting bracket. Tonight I pulled the old speaker and plugged in the wiring harness and attached it to the new speaker. The speaker works, but it is extremely quiet at 75-90% full volume. I plugged the old speaker back in to double check the factory wiring and it worked fine. So I plugged back in my Crutchfield harness and new speaker and same thing, very very quiet. All the other speakers still work fine. Has anyone had this experience? I have no idea what to try next to figure this out. Thanks in advance.
