My SB17MFC woofers are mounted in my Civics stock location: Low in my front doors. So when I'm in my car my left leg is in front of the woofer.
So I'm guessing tuning while seated will give me the best results.
But how can I mount the mic where my head is?
Another question. I usually drive with my window slightly open. I'm guessing this affects the cabin gain. Anyone ever tested how a slightly open (about 5 cm) window affects the sound?
