Much effort is expended by us to find the correct placement for our subs in our home stereo and theater setups. Most people just stick subs where it's convenient, I want to find the best place to put my sub yet still have trunk space. I plan on using 2 subs, either in 1 or 2 enclosures, I just do not know which way the subs should face. Should they face toward the cabin, out toward the back of the car, or toward each other (naturally not directly facing each other). Also, I will need to vent the cabin to the trunk, correct?
