Ok, So I found a box that will fit under my seat and will hold my 12" sub. Only problem is it only has .653 Cubic Feet and my sub says it needs 1.2 Cubic feet at 150 Watts. So If I turn the Watts down will this box work. I used to have a chart when I got the subs and it told me how many watts for Cubic feet but I can't find it and don't know if it went down that low in volume.
That airspace is a guideline many people use the smaller boxes and dont have issues It may not hit the deep bass as well as before
I have 2 12 MTX subs in my boat and due to space issues I went smaller ~ 1 cube and the subs are rated to have 1.5 for best sound everyone compliments me on how good my boat sounds
I made a custom box for a friend of mine 2 12's tucked under the seat on a 98 silverado fiberglassed bottom full width and got 1.5 cube per sub out of it too took us about 8 hours total looked amazing when done
If you are worried about space and want to make your own feel free to hit me up with questions Ive made alot of fiberglass boxes/wood custom boxes
