ok, i had the avic d3 installed for about 2 weeks now... i love it.
it's installed in my scion tc, all stock speakers.
the front sound is amazing, but the rear speakers are very low, even if i bump the fade all the way to 8 to the rear.
how would i go about to fix this problem, with the old scion stock pioneer unit, the rear sounds were loud and crisp, but now ive gotten to the point(i thoguht i could get used to it, guess not), where i need to have a balance in front/rear.
