Posted February 24, 200916 yr Will four eD nine.1s amps be enough power to push 4 BL 18s.Btw what is the minimum air space required ported per sub?
February 24, 200916 yr Those amps will work fine.I personally would not do an 18 in less than 6 cuft. You can get away with 5 cuft. . .

February 25, 200916 yr Author Can someone please give me specs on a box for a BL18 please include measuremets and port displacement, ideal airspace 6cf. tuning 33hz or lower. Edited February 25, 200916 yr by BassMan808
February 25, 200916 yr fi recommends 5-10ft^3. go somewhere in there. tuning will depend on what you want out of it. port displacement cant be figured out w/o tuning, box size, or port area...so go figure those out first. how much space do you have/are willing to give up?
