I have a question about sub woofers and sealed enclosures. I am looking at purchasing a prebuilt box for under the rear seats of my 2011 dodge ram crew cab. The box says the air volume is 1.5 cubic feet. The subs I am looking at, have a working range of 1.0 - 4 something. My first question is what imipact will it have on the sound or performance it the box air vloume is near the lower end of the subs range? Second, the box says it has 1.5 cubic feet, but it is also built for two subs. So, what is the impact if there are two subs, each needing 1.0 cubic feet, or does it matter that there are 2 and it does not make a difference? Does this make sense? The subs I am going with are Kicker CompVR 07CVR124. I would appreciate any help. I tried searching everywhere for this answer, but could not find the right keywords to bring up any previous disucssions on it. Thanks again!
If total box volume is 1.5 cubic feet, and you install 2 drivers in it, each driver will see .75 cubic feet. (actually a little less due to driver volume). The net result will yield in a sound that is lacking any serious bottom octaves, and a very large peak in sound at the upper end of the subs frequency range. you would not like the results. In this situation you would be far better off using one sub instead of two.
