marine87 Posted December 26, 2009 Report Share Posted December 26, 2009 Merry Christmas to all! I know I'm a few days late, but it's the thought that counts, right? Lol anyway, I've finally measured the back of my truck! Alright, so the width of my truck is 48". I want the box to be 24" tall, so I can still see out of the back window. And from the backseat to the rear hatch minus 6" is 36"( I was told that you want at least 6" of clearance for the port so there isn't interference.) so, the math- 4 feet x 2 feet x 3 feet: 24 cubes! I was surprised at that number. I didn't know I had this much room! Now, I don't know how to calculate the box displacement. So, I went to Rockfordfosgate.com and used their box wizard. Turns out I have 20.89 cubic feet internal volume. The website mentioned driver displacement. I don't know where to find this. Is there a symbol for it? Ex. RMS- root mean square. I'm trying to see if I have enough room for 4 AQ hdc318's. Any help will be greatly appreciated. Corporal, USMC Link to comment Share on other sites More sharing options...

marine87 Posted December 27, 2009 Author Report Share Posted December 27, 2009 iirc the HDC3 18 displaces somethiing like .2 cubes ill see if i can find it on their site Thanks so much man. I looked at the website myself, and I didn't understand the terminology. Do you think I have the correct space for 4 of them? 5 cubes per 18, I think they'll do well. But I don't have any experience with them. Anyone got .02 they wouldn't mind sharing? Corporal, USMC Link to comment Share on other sites More sharing options...
