So i have a few questions, since i have never owned a car until now, i have always had trucks, and suv's. What is the best placement, subs back port back, or subs up port back? if i do subs back port back, im more limited to space, i would have W-37" H-13" D-14". If i go subs up port back i have W-45" H-16" D-20" which leaves me roughly 6.75^3 before displacement. Any suggestions are greatly appreciated. I have more questions as soon as these are answered.
