Re: New system for my 1999 Toyota 4runner
2 15's in a 4th order will not fit just behind the back seats, you have about 8 Cubes total and that will completely fill up the cargo area.
This is the back of my 97, the battery takes about 6" out of the space the box could use, my box is 7.3 Cubes, you may be able to squeeze a little more space out of it with Aero ports.
