Ok before you all jump on me for not searching this, i have been researching this for a couple weeks now. I cannot find the answers to all of my questions and i am still confused.
So i have an 09 double cab and i want to take out the plastic behind the back seat to build a sub box which will hold 2 JL Audio 10W0v3-4's. I have measured multiple times and am still not sure if i will need to make 2 boxes, one on each side, or if i can make one large box. i want sealed boxes, not ported. I have read that i should use 3/4" or 1" MFD board but i am not sure which one is better. Also i have been using http://www.bcae1.com/spboxnew2.htm to help me figure out my volume. i know that i need .65 for each sub so how much bigger should i make the box to overcome for the space which will be taken up by the sub once i put it in? Also does anyone have some dimensions which i could use to build a good box?
