Just wondering about the door speakers. I bought a set of speakers for my doors and plugged them into the rear just to test them out and they sounded good and loud. then i plug them into the door and they are much more quiet, are they wired like that or is it a coincidence?
The front speakers share a circuit between the door and the dash.
So you've got current going to two speakers instead of one from the same size amp channel. So yes, the individual speaker output in the front will be less. The door position also fires directly into carpet instead of up against a piece of glass like the dash and rear deck. That has an effect.
