i am new on this site so some of these questions may seem a little stupid as I am not a genius when it comes to my car audio. i have an older DB12 which i used to run in my jimmy and became very fond of. i am now planning on installing it under the seat of my 02 wrangler and am working to make it fit as it is going to be very close. the sub will be firing down towards the floor and i am trying to figure out how far the sub should be from the floor for optimum sound. i believe the rule is half the diameter of the voice coil. am i to assume that that is 6"? i no longer have all the specs for this sub and they seem to be hard to find. thanks to a diagram from jeepforum i think i should have about 3" from the floor. hope thats enough as i don't want to use any other sub. i also need to know how much space the sub needs to be from the back of the box. please help me with these questions. thanks.
