i tried searching but didn't come up with much. we thought my wife's front door speakers were shot because no high tones would come out of them. we replaced them only to have the same outcome. i figured out that there must be a low-pass filter in line somewhere, but i need to know how to bypass it. it has an aftermarket pioneer head unit with one of the oem adapter kits that wires in to the pioneer wiring. anyone know the easiest way to bypass this? i was thinking of just running new wires from the door to the head unit, but it doesn't look like a fun chore

 

The amp for the door speakers is located up behind the passenger side dash speaker and you can cut and grab the door wires there.

left door + light green/red
left door - light green/white
right door + light green
right door - light green/yellow

Double check the colors but I'm pretty sure these are it. Good luck

 

the easiest way will be to run new wires, or replace the amp, if you run new wires, you should run them to all the speakers, and keep in mind if you have dash speakers and door speakers you will have to make sure your radio can handle the new load if you want to do that, well just PM me and ask no point in explaining if you are not going to do it ...

 

thanks a ton for the diagram! i just ran some short wires from the head unit to the green wires that were the outputs from the factory amp. pretty easy once i had the diagram.
